Another Worry for Cicadas: Cedar Beetles

Kermit the Frog always said, "It's not easy being green."  Well, I've decided that it's not easy being a cicada either.

My dogs absolutely love to munch cicadas and have been known to catch them in mid-air.  If they find one on the ground, they'll often hold it in their mouth for a little bit to get it to buzz before they chomp down and eat it.  A canine "Fizzy", I guess.

Then there are more "normal" predators like birds and, especially, the huge wasps known as cicada killers.  Female cicada killers hunt down a cicada, sting it to paralyze it (but keep it alive), drag it back to their nest in the ground, carry it below ground, lay an egg on it and seal the brood cell off.  When the egg hatches, the larval wasp eats out the paralyzed, living cicada, pupates, and emerges the next year to repeat the cycle.  An effective population control mechanism for cicadas, although it's extremely unsettling to think about.

I suspect that moles eat a fair number of cicada nymphs, too, as the nymphs feed and mature underground.

Now, I've learned about another animal that feasts on cicadas, specifically on the nymphs while they are still underground - the cedar beetle, Sandalus niger, also descriptively known as the cicada parasite beetle.  I've been observing these large beetles all around the yard over the last few days.  Most often, I'm seeing them on honeylocust trees.


These are fairly large beetles - many are close to an inch in length.  I first noticed one when I saw a big brown beetle being eating by 2 wheelbugs.  I've never seen TWO wheelbugs eating the same beetle before!  I took photos and tried to identify the beetle, but I couldn't quite make it out.  It looked somewhat like a longhorn beetle, but I didn't see long "horns" (antennae) on it.

While I was photographing this interesting vignette, Greg called me over to a nearby lacebark elm, saying that he'd just seen a big black beetle fly into it.  He showed me where she had landed and I took several photos of her;  she appeared to be laying eggs on the underside of a dead limb.

I started to go back to taking photos of pollinators on asters, when I felt something on my shoulder.  Looking down, it was a large black beetle with one of the elytra (thickened wing covers) missing.  I brushed her to the ground, where I photographed her, wondering how she had lost her elytra.  Then I picked her up and put her in the elm tree, thinking she probably got interrupted during egg laying.

Only when I edited the photographs this evening did I notice that all the white "innards" showing were actually larvae(?) or pupae(?) of some other insect that were massed inside her.  I have no idea what they are...but I'm submitting the photo to BugGuide to see if anyone there can help identify what was going on with her.  (Parasites eating parasites.  Sometimes the natural world is really complex in its creepiness.)  Did the larvae have anything to do with how she lost her wing cover?  I have no idea.

Next, I noticed another, similar looking beetle being eaten by a wheelbug on a nearby honeylocust trunk.  As I stood and took photos, I heard and felt yet another big beetle - the 5th one - fly by my head.  It was a male, judging by its smaller size and more slender body, and it landed on the tree trunk right in front of me and starting searching all around.  Its antennae were really interesting, especially when the beetle fanned them all the way out.

While all of these beetles were grabbing my attention, I was also hearing a clicking noise that sounded very much like the rhythmic pattern of a field sparrow, which is often likened to the sound of a bouncing ball.  This noise, however, was more "insect-like" than a bird call, if there is such a thing.  I never did find out what was creating the sound, but I don't recall having heard it before and I wonder if it was some sort of mating call between the cedar beetles.

Before I went in for the evening, I took several more photos of each of the different beetles I'd observed, and  I also found a 6th beetle on the underside of a honeylocust branch. This was another female, based on the size and shape, but I didn't get any clear photos of her.

Looking through Insects in Kansas, by Glenn A. Salsbury and Stephan C. White, I found the tentative identification of my beetles, which I confirmed on BugGuide.net.   They were all the same species, Sandalus nigerInsects in Kansas had noted that males often had blackish-brown wing-covers, rather than black, and on BugGuide, I saw the difference in antennae between the males and females.  There wasn't a lot of information given about the species on its information page at BugGuide, but it was noted that the adult beetles are very short-lived.

I've gone back and picked up the "empty" beetles discarded by the wheelbugs after they were through eating them so that I could examine them more closely, plus I've been able to find a couple more dead specimens.  Sunday, October 19th, was the only day that I saw so many living individuals, although I've seen one or two more each day since then.  I have not heard the clicking noise again.

I have seen one more instance where two wheelbugs were eating the same cedar beetle.  Do wheelbugs do this with any large insect, or is it only with cedar beetles?  I'll be keeping my eyes open to see what I observe in the future.

Isn't the complexity of life fascinating?!

Surprise! - A Gray Treefrog in the Garden

We've been away in Boston and Vermont for the past 10 days, so a lot has happened in the garden while we've been gone.  The aromatic asters were just beginning to open as we left and I was afraid that I would miss them, but I didn't need to worry.  They are still in full and glorious bloom!

Greg and I did a walkabout yesterday and I took a huge number of photos, most of which still need to be sorted and studied, edited and identified before I can think about sharing any of them - but I have a couple photos showing one surprise visitor that were easy to quickly focus on and that I thought you might enjoy....

After our walkabout, Greg decided to add some old straw to one of the vegetable garden beds for the winter.  As he picked up the decomposing bale to redistribute it, an amphibian jumped out.  Greg's first impulse was that it was a toad, based on location, general size, and general lack of shine to its skin.  It looked different than most of our toads, though, so he called me over to take a look.

The animal was rather small and it wasn't warty enough for a toad, in my mind,  plus the shape was wrong, so I started thinking about the various kinds of frogs that it might be.  Meanwhile, of course, I took as many photos as I could without disturbing the animal or trying to pick it up.  When it hopped, it flashed the most vivid bright yellow on the lining of its hind legs...but that yellow was very hard to see when it was sitting still.  That HAD to be diagnostic.

Over dinner, I opened my copy of Amphibians, Reptiles, and Turtles in Kansas, by Joseph T. Collins, et al., and turned almost immediately to the page talking about Cope's Gray Treefrog (Hyla chrysoscelis) and Eastern Gray Treefrog (Hyla versicolor).  The two species are apparently only distinguishable from each other based on their chromosome number or the size of their blood cells, so I am simply calling this a Gray Treefrog (Hyla sp.).  Even based on the general natural history given, I'm perplexed - Cope's is said to be more arboreal than the Eastern, but to need less humidity in its environment.  Since we are at the absolute western end of this pair of species' range (and thus in the driest part of their range), but the individual was found under an old hay bale in the garden, I'm still split between the 2 options.

As of the writing of Amphibians, Reptiles, and Turtles in Kansas, which was copyrighted in 2010, the Gray Treefrog species complex was apparently expanding its range westward "along riparian corridors".  The species occurrence map shown in the book does not show any occurrences documented in Sedgwick County, but there are a few in the counties generally south and east of us.  It would seem that our individual may be one of the "pioneer" Gray Treefrogs, expanding their range west. So we may have a new county record!

This is the sort of find that brightens my week and makes me feel that we're on the right track in our land management decisions.

Fabulous Blooms and Friendly Brains: Kansas Native Plant Society Wildflower Weekend

Last weekend at this time (2 p.m., Sunday afternoon), I was just arriving home after a great weekend getaway.

For seven years I've been thinking about going to this annual event, but something always got in the way.  One year we were heading over to Winfield to go to the Walnut River Valley Music Festival.  Another year we were on a trip to England and Norway.  Yet another year we were getting ready to leave for a trip to Germany.  The year before last, I was getting ready to take an adopted dog down to our daughter in Florida. 

"Where did you go last weekend?  Why did it take you so long to make it?" you ask.  "It sounds like you were doing LOTS of traveling already, so that can't have been the problem."

"To the Annual Wildflower Weekend of the Kansas Native Plant Society," I answer.  The AWW, as many people seem to call it.  As to why it took me so long to make it a priority to attend, I can't give you a rational answer.  All I can say is that I'm glad I went this year.

Each year KNPS's Annual Wildflower Weekend is held in a different location within Kansas, but it's always on the same weekend, the 3rd weekend in September.  No matter where the AWW is held, the weekend seems to hold lots of tromping around through impressive prairie sites full of not-so-common native wildflowers and grasses, as well as a lot of camaraderie with other souls who value the chance to spend time out tromping around and looking at plants too.

This year Greg told me to go.  I politely scuffled my feet a little, feeling quite guilty at leaving him home alone to take care of the homestead for 2 days while I went out to "play"...then I shoved the guilt down, made my reservations, and skedaddled.

I'm so glad I did.  I had a great time and I had a chance to see some beautiful sights and sites.  Most exciting of all, I reconnected with a couple friends from many years ago, had a chance to meet two friends I've previously known only through blogging, and became acquainted with several other folks who are new friends in the making.  The most hopeful part is that all of us share a passion for plants and animals and wild spaces...and learning about the web of which they are all a part.


In the photo above, Theresa and Melanie (with Melanie's daughter Cami) are two friends I've met entirely through garden blogging.  It was so much fun to share time with them in person while poking around and looking at plants.  Cami seemed to have a great time exploring, too, and she and I explored our common interests in taking photos and looking at insects and rocks.

This year's AWW was based in Pratt, Kansas, home of the Kansas Department of Wildlife and Parks.  Not surprisingly, our first field trip was to the KDWP museum and to the pollinator garden right beside it, in the southeast corner of town.  The Pratt Master Gardeners have done a superb job of putting together a beautiful and interesting pollinator and native wildflower display garden, complete with a gorgeous pool, for which they received a well deserved award from KNPS.

Whispered on the wind were comments about possible expansions of the native plant display gardens, as well. Wouldn't that be awesome?!

During the course of the weekend, we got to explore 5 different prairie sites - 3 in the Red Hills south of Pratt and 2 sand prairies east of Pratt.  The last site also included a section of the Ninnescah River, so we were able to do a little riparian scouting as well.  Almost all of the sites were on privates land that had been graciously opened up to us to explore, so I don't want to be too specific about the locations.  The photo above show the group moving away from our cars, beginning to explore a site in the rugged landscape near Sun City.

I have no idea what the official plant list (i.e. total species count) for the weekend was because I was doing some landscape gazing, some insect hunting, some photography teaching, and a lot of chatting...besides looking for flowers and grasses, of course.


This delicate white beauty is the flower of the Sand Lily (Mentzelia nuda) in the Red Hills of Kansas.  Such a beautiful, soft looking flower on such a thorny, spiky plant!

Broad-leaf milkweed (Asclepias latifolia) doesn't look all that interesting in this photo, but it really captured my attention in the field...maybe because it was SO green and lush looking in an otherwise scorched looking landscape.  The leaves almost looked like cabbage!  The remnants of the pods were actually rather small and cute;  they were found under and between the leaves, rather than at the top of the plant.  This is one that I want to try to find for our garden.  USDA Plant Profiles does show Sedgwick County as part of this plant's range.

Isn't this guy gorgeous?  This is the rainbow grasshopper (Dactylotum bicolor), also commonly called the pictured grasshopper.  It's posing on dotted gayfeather (Liatris punctata), which was in bloom in all of the prairies we visited.



I was lucky enough to get a glimpse of this insect accidentally.  Do you see it?  It's a walking stick, colored perfectly to blend in with the grass.  The only reason I saw it was that it moved as I knelt down to look at a nearby flower.  Sad to say, I don't have a good enough photo of it to risk trying to get it down to the genus level, let alone the species level.  (I would welcome anyone's help on this matter, though.)

A last extra punch for the weekend was getting to hear Iralee Barnard speak about grass identification (an area in which I am sadly lacking) and then being able to purchase her new book, Field Guide to the Common Grasses of Oklahoma, Kansas, and Nebraska.  It's a great help and, after reading it, I already feel more confident in my ability to tackle a few of the more obscure grasslike plants that I'm seeing around our prairie at home, Patchwork Prairie.

Will I return for another AWW?  Absolutely!  It was an AWWsome chance to become active in a human community of interesting and fun plant nerds!  It was also an AWWsome chance to roam around and learn about plants in natural areas that are normally unavailable for "regular folks" to explore.  What wasn't to like?!

Diversity!

Greg gave me a gift for Christmas last year - Access (the software program, which unfortunately doesn't automatically come with the home version of Office) so that I could begin to keep a coherent database of all the plants and animals that I've found on our 10 acres.

I have been slowly working on this project in the intervening months, and I'm far from done.  For the most part, I've been utilizing the photos I've taken over the years to remind me of what I've found and where I've found it.


For example, I saw this flower beetle (Batyle suturalis) on Black-Eyed Susan (Rudbeckia hirta) in the Back Five early in July this year; both species are now in my database.



The wonderful folks at BugGuide.net are probably quite sick of me, as I've been submitting quite a few photos for their help with identification - which has been wonderful and greatly appreciated.  I can usually get an unknown insect down to order and often to family, using my experience and (if necessary) Borror and DeLong's Introduction to the Study of Insects for its excellent keys .  Then I try, utilizing BugGuide's online guides, to get the insect down to genus and species, but without actual keys specifying what I'm looking for, it can be hard.  It's at this point that I will submit an image for help.


Other species are often easier.  For example, I've been birding for years, so I have a reasonable familiarity with bird species and I can trust my identifications and the species lists I've been keeping since we moved in.  (Besides, it is much easier to figure out which of 450+ possible species a bird is compared to figuring out which of thousands of possible species an insect is.)  Below, for example, is a red-winged blackbird watching a little blue heron, who hung out in our lagoon for several days in 2009.

There are a variety of books and online resources I go to for plant identifications:  Michael Haddock's book and website on Wildflowers and Grassses of Kansas.  Janet Bare's book, Wildflowers and Weeds of Kansas.  Stephen's book, Trees, Shrubs and Woody Vines in Kansas.  And many, many more.

I've recently purchased Bradley's book, Common Spiders of North America, to improve my ability to identify the spiders that I'm seeing.  BugGuide is also useful with spiders, and I have a few other guidebooks (although most are much less comprehensive than Bradley's).  Below is a male jumping spider (Phidippus clarus) which I photographed last summer hanging out on giant ragweed (Ambrosia trifida).

There are, obviously, many more references that I use to compile my species lists, but that isn't the point of this post.  Right now, according to my Access database, I have 201 plant species that I've found (or planted) on our 10 acres, 157 species of insects, 3 species of amphibians, 8 species of mammals, 1 species of snake, and 5 species of turtles.  (I have found quite a few more species of amphibians, mammals, snakes and turtles than that, but I haven't put them into my Access database yet.)  My yard list has 121 bird species so far.  That includes birds seen ON our property, as well as FROM our property (i.e. flying overhead during migration or seen from our property but physically on our neighbors' land).  I haven't started a list of spider species yet, but in looking in my photo organizer, I easily have at least a dozen different species.  Then there are the assorted invertebrates not covered by "insect" and "spider" catergories, species like prairie crayfish, roly-polies, and daddy longlegs.


Here is a boreal chorus frog (Pseudacris maculata) in the buffalo grass (Bouteloua dactyloides) of our front lawn last August.



So, in the 7 1/2 years we've lived here, I have documented (so far) 310 animal species and 201 plant species sharing our 10 acres with us.


Why am I posting about this right now?  Because in yesterday's Wichita Eagle, there was an article about Chisholm Creek Park in northeast Wichita.  The article was actually about algae in the lake there, but there was a brief aside saying that "[t]he park is home to 163 species of plants and 214 species of animals...."  Chisholm Creek Park is large - 282 acres, according to the website of the Great Plains Nature Center, which is located there.

I have documented about 25% more species of plant species and almost 50% more species of animals on our 10 acres than have been documented in the 282 acres of Chisholm Creek Park in the same county.

Does this mean that there really ARE that many more species on our little 10 acres than in Chisholm Creek Park?  No.  Absolutely not.  The species summary list on the Great Plains Nature Center site above does not give any number of species at all for invertebrates or grasses, for example, and their numbers for birds, mammals, reptiles and amphibians are all greater than the number I've observed on our property.  Chisholm Creek Park also has fish species, while we have no year-round water habitat except our lagoon.

I've just been more meticulous about recording (and identifying) the variety of species I've found here, particularly the species of insects and other invertebrates, than the folks in charge of that park have had the time or the inclination to do.  Still, it was definitely a psychological boost to realize just how diverse a piece of property we actually have!

Do you keep any sort of species list of what you've identified on your property?   If so, what sorts of insights or discoveries has that process given you?

Serendipity...Or Lives That Want To Be Shared?

Okay, this is a warning.  I am going to sound a little "Woo-woo" in this post.  I can't help that because sometimes that's just how I am.

So, with the appropriate warning out of the way, I have to confess that sometimes it seems as if certain animals consent to show themselves to me so that I can photograph them.  How else to explain the chance to photograph the fly attacking the hornworm last week? 

Or the funnel spider that sat at the entrance to its hole and just looked at me one morning last summer?   That's very unusual behavior for a funnel spider.

How about last week, when the scissor grinder cicada (Tibicen pruinosus) flew to the stem of a sunflower, about 5 feet from where I was weeding in the vegetable garden, and started to loudly sing away, making sure I had the chance to put his song and his appearance together. 

He even sat there singing while I stood up and photographed him!

Then there was the hanging thief robber fly (Diogmites sp.) that landed right in front of me to munch away on her wasp victim, while she dangled nonchalently from a single foot hanging onto the dry tip of an aster leaf.

Look how gently she seems to be cradling her prey.

I shouldn't forget the beautiful (and BIG) garter snake that posed prettily on the back path earlier this summer, obviously replete from a satisfying meal of (probably) cotton rat or baby rabbit. 

I walk the paths with 2 large German shepherds and I make little or no attempt to be quiet or to keep the dogs on heel.  That snake HAD to know we were coming!

Don't get me wrong - I am definitely not complaining.  I absolutely love getting glimpses into the lives of the animals that share our "little bit of Earth" with us.  It's a privilege and an honor to share their stories with a wider audience, too.

I'll leave you with one last animal story I was privileged to witness recently and with the related thought that it sparked in me.

I saw this David and Goliath story in my front garden just last week.  How in the world did that little crab spider manage to catch - and especially hold onto - that huge swallowtail butterfly?  The butterfly was obviously old - it's tattered wings hint of multiple adventures survived.  Was the butterfly just too old to have the energy to get away this time?  Or did it, somehow, know that its time was done and "consent" to become a meal for the little spider, passing along its energy to help the wheel of life spin just a little bit further around?

Do animals "consent" to be eaten and to become part of the food chain?  I've read that the Native Americans always used to say thanks to the animals they hunted for giving their lives to them for sustenance.  Was that a willing choice on the part of the animals?  Or was that simply an acknowledgement, on the part of the Native Americans, that they were taking the lives of other animals to support their own?

Of course I have no answers to my questions and I know that I'm being fanciful, especially in imagining the animals' desire to have their stories shared on the internet, but thanks for reading this and letting me indulge in whimsy from time to time.  I hope you'll always share the chance encounters you have with wildlife in your gardens - and the stories behind those encounters, too!

Double-banded Scoliid Wasp

Double-banded Scoliid Wasp.  Scolia bincincta.  What the heck is that?  Won't it sting me?  It looks menacing!

Well, it may look menacing because it's a big, black wasp, but the main animals that scoliid wasps menace are beetle larvae, especially beetle larvae in the ground.  You know, those things in your lawn called grubs?!

Every summer, Double-banded Scoliid Wasps are frequent visitors in my yard, especially to goldenrod and brown-eyed Susan blooms.  I doubt it's a coincidence that I rarely see June bugs any more, no matter what time of year it is.  Apparently, the female scoliid wasps dig down into the soil, sometimes following a grub's own tunnel, find the beetle grub, and then sting the grub to paralyze it.  The female often lays an egg on the grub then - but not always.  Even if the female doesn't lay an egg,  the grub will never recover from being paralyzed and therefore will never mature to reproduce.

Scoliid wasps, it naturally follows, are important predators on June bugs, May beetles, green June bugs, and even Japanese beetles! 

Meanwhile, the adult scoliid wasps feed on nectar and pollen, so they are frequently seen at flowers, which is where I almost always notice them.  Looking at the photo above, you can see the amount of pollen on this wasp.  Not surprisingly, scoliid wasps also act as pollinators, although they are not as efficient at that process as many of the native bees are.

According to BugGuide.net, there are 20 species of scoliid wasps in the U.S., spread among 5 genera, so there's a good chance you, too, can have scoliid wasps in your yard and garden.  Insects in Kansas shows 3 different species, in 2 genera, but there are probably more in our state.

By the way, if this wasp still looks dangerous to you, this is another of the myriad of solitary bees and wasps that won't sting you unless you physically try to hold them in your hand or accidentally step or fall on them.  Scoliid wasps are not aggressive towards humans.

Scoliid wasps are wonderful natural predators.  I hope you discover a species or two of these beautiful animals sharing your garden too!

The Fly and the Caterpillar: Not a Love Story

As I was doing a quick look-see in the vegetable garden yesterday, I heard a fly buzzing.  Why a buzzing fly caught my attention, I really can't tell you, but it did.  Perhaps it was because the noise was coming from the top of a tomato plant, which isn't normally fly country.  Anyway, I stopped to see what was going on.

At first I didn't see anything, then a movement attracted my attention.  Was that a smallish horn worm? 

I kept looking, finally able to see the outline of the caterpillar against the underside of one of the tomato leaves tucked in a ways.  Suddenly I saw a quick, dark movement and the caterpillar thrashed wildly.  What was going on???

As I watched, it became obvious that a fly was attacking the hornworm.  Every time the fly circled around and came near, the hornworm would move.... Trying to defend itself?  Trying to attack the fly?  Trying to keep the fly from landing?  I couldn't really see what was going on, but I took a series of photos, hoping to capture something with my lens that my eyes couldn't see.

Here are the best shots from the encounter...

The hornworm when I first saw it.

The first view of the fly.

Another "fly by" by the fly.  (Look carefully - you can see the fly's legs above the caterpillar;  the body of the fly is mostly hidden by the tomato stem.)

The fly comes back for another go-around.

And another attack - Fly attack #4...

This one lasted a little longer and the fly seemed to land on the caterpillar's body, despite the hornworm's thrashing and attempts to defend itself.

Fly attack #5.....  (You can just see the eyes of the fly coming into focus to the left of and slightly below the caterpillar.)

Fly attack #6...

Now there's fluid on the back of the caterpillar;  the fly has definitely made contact.

Still the fly comes back again....

But this seems to be the end of the attack.  A drop of "blood" on the back of the caterpillar remains, but the buzzing fly is gone.

According to my camera's time stamp, all of these photos were taken within a 2 minute window.  I don't know how long the attack had been going on when I chanced upon it.  Still, overall, the action didn't last that long.

I am assuming that the fly was a female and that she laid at least one egg in the caterpillar.  Judging from the fly's hairy abdomen that I could see in the photos, this was probably a tachinid fly.  If that's the case, the hornworm will go back to eating as if nothing has happened, but when it goes to pupate, the fly larva that has grown inside it will take over and kill the developing moth.  The hornworm pupa will actually only produce one or more fly pupae, which will, in their turn, produce more tachinid flies to carry on the cycle.

I knew that tachinid flies were parasitoids of caterpillars, but this is the first time I've actually witnessed the interaction between the caterpillar and the fly.  I see many, many tachinid flies in the garden, especially in the fall when they are feeding at my asters, so I knew this sort of event had to be occurring.  Adult tachinid flies are pollen and nectar feeders...and good pollinators.  Hornworms, while I think they are cool and interesting, are pests on tomato plants.  This is natural predator control at its most basic.

Life is not particularly gentle, but it tends to balance itself when allowed to do so.  Sometimes the variety of feeding strategies truly boggles my mind.   What predatory insects have you seen in YOUR garden lately?

Insect Music: Cicada Songs

When I posted my cicada photo on Bug Guide, for help with identification, I was also given links to pages that have recordings of cicada songs.  For example, there is the page called "Cicadas of the United States and Canada East of the 100th Meridian".  (Note:  I can't get links to work properly in this part of the post, for some unknown reason, but you can type the title into a Google search and the site will show up at the top of the list.) 

Like birds, each different species of cicada has a different song to help it locate a mate of the proper species.  Apparently it is sometimes easier to identify a cicada from its song than from its appearance...for humans, if not for cicadas. 

It's amazing!  When I go outside now, I feel like I'm experiencing an entirely new layer of awareness.  Suddenly, my mind tunes into the specific rhythm and tone of the cicada songs I'm hearing, on top of the familiar bird songs, the visual beauty of the leaves and flowers, and the feel of the wind on my skin.  I'm astounded at how much richer my outdoor experience has suddenly become!

Here are some of the various cicadas that I have identified in our yard.  If you go to the above page with its cicada songs, you can hear the different song for each of these species.  (Sorry, I tried to link each song below the photo, but a couple links worked and the rest didn't.  It seemed less confusing to just send you directly to the page itself, which is very easy to navigate, than to have some functional links and some dysfunctional ones.)  

Shown above, the bush cicada, Tibicen dorsatus, that I talked about in my last post, has a long, loud monotonous drone.

On the other hand, another cicada that I see fairly frequently, the superb prairie cicada, Tibicen superbus, has a song that is generally quieter, interspersed with louder rattles that almost give a wave-like feeling to the sound. I find that the song of this cicada is one of those iconic sounds that transports me outside to a hot summer day, no matter what time of year it is!

I don't have a photo of the next species, but when I went out early yesterday morning to take the trash out to the curb, the scissor grinder, Tibicen pruinosus, was calling from the honey locust hedge.  Here is what it sounded like (and probably looked like, if I had been able to see it!)  Note:  this is not my recording.
A fourth cicada species that I've found in the yard is the Plains Dog-Day Cicada, Tibicen auriferus, (shown above in a somewhat unusual color pattern).  The Plains Dog-Day Cicada's song has the pitch of a metallic buzz saw to my ear.

The fifth species that I've identified, so far, is the Whitened Dog-Day Cicada, Tibicen dealbatus. To me, it's song sounds like 2 insects combined into one body:  a droning cicada and a cricket, fighting it out inside the cicada's abdomen.

As a side note, in cicadas, only the males sing.  Unlike grasshoppers or crickets, male cicadas do not stridulate, or rub various parts of their body together to produce their song.  Instead, male cicadas have paired membranous structures in their abdomens called tymbals, which vibrate rapidly, the sound resonating within the body of the cicada.  Some cicadas sing so loudly that their song could cause damage to the human ear if the insect were singing right beside it. 

It's going to be an interesting challenge now to see how many different cicadas I can learn to identify from their calls!  It'll be fun to match up photos with calls as well, helping me to determine just exactly which different species I'm sharing our land with.  The more I learn, the more I realize I don't know.
