Hairy Elephant's Foot, A Surprising Pollinator Magnet

At least until you get to know them well, there are some plants that are hard to get excited about.  Often that's because they don't have fascinating foliage or stunning flowers.  Just because a plant isn't classically beautiful, though, that doesn't mean it isn't greatly loved by pollinators and other insects.


Frankly, Hairy Elephant's Foot (Elephantopus tomentosus) is just such a plant.  It is a hard plant to photograph well.  For the first few months of spring and summer, it consists of a few large, hairy leaves lying flat on the ground, all coming from a central point.  Not glamorous, but definitely easy to photograph.

It's in July that the trouble begins.  The plants start to put up their flowering stalks, which rise for 12-15" above the basal leaves.  There is hardly any foliage on these stems at all.  At the top of each stalk, sudden branches stick out awkwardly, each crowned with a trio of small, bright green, hairy, pointy "leaves".  Nestled within those bracts, the small, lavender flowers open, dainty and subtle.  They open in the morning and close in mid afternoon.


These delicate little blooms wash out readily in a photo, especially in any bright light.   Their dainty airiness just looks sparse on "film", even though it looks charming en masse in real life.

A great plant for shade, Hairy Elephant's Foot grows well there, although it tends to be rather widely scattered.  Unexpectedly last year, I had an experiment in our yard when a neighbor cut down several large trees right near our joint property line and turned what had been almost complete shade into full sun, for 5-6 hours each day.

I expected the shade-loving understory plants that grew in that area to frazzle and die, which many of them did.  The Hairy Elephant's Foot, however, had a banner year, blooming prolifically and attracting an amazing number of pollinators and other insects - 21 different species that I was able to photograph!

So how do I best share the amazing number and diversity of insects that I observed?  A simple list, even illustrated with photos and spiced with bits of (hopefully) interesting information, seems overwhelming and ultimately boring.  So I thought I would talk about a few of the "categories" of insects that I observed:  1) Butterflies and Skippers, 2) Pest Control Squad - Solitary Wasps and Syrphid Flies, 3) A Predator and Prey Duo, 4) Native Bees - Pollinators Extraordinaire, 5) Flies, and 6) Passersby.

Two of the species I photographed using Hairy Elephant's Foot last summer are considered somewhat rare or threatened:  the American Bumble Bee and the Yellow-thighed Thick-leg Fly, a form of syrphid fly.  Both are shown below in their appropriate categories.


BUTTERFLIES AND SKIPPERS:

It's always fun to start with "the pretties" - and I've come to think of butterflies and skippers as "flying flowers", the prettiest group of insects overall.

Butterflies and skippers (and moths) are more than just pretty, though.  Their caterpillars are, according to Dr. Doug Tallamy, one of the primary ways that energy, captured by plants from the sun, moves up the food chain.  EVERYTHING seems to eat caterpillars.  For those of us who are birders, that's especially true of most of the songbirds, 95% of whom raise their young on insects, especially caterpillars.  

So in feeding adult butterflies and skippers, Hairy Elephant's Foot is also helping to keep those adults in our yard, thus supporting the production of caterpillars to feed the upcoming generation of birds and other animals here.



Eastern Tiger Swallowtail (Papilio glaucus), 8/19/23.   With a variety of host plants in the Magnolia and the Rose families, Eastern Tiger Swallowtails are fairly common across a wide range in North America.  In our yard, I'm guessing that they usually spend their larval time on Tulip Poplars, since we have several extremely large specimens of that majestic tree.  It's often easy to overlook the fact that trees can serve as important host and pollinator plants.



Zebra Swallowtail (Eurytides marcellus), 8/19/23).  If you don't have pawpaws, you won't have Zebra Swallowtails.  Our neighborhood has a plethora of pawpaws, in great part because deer don't like it and so it spreads with little competition in our deer-challenged yards.  Consequently, we have a plethora of zebra swallowtails.  Most of the time, these ethereal beauties are just floating through, but Hairy Elephant's Foot got them to stick around for a bit.



Common Buckeye (Junonia coenia), 8/20/23.  This was the first time I had seen a Common Buckeye in our yard.  I've started planting Carolina Petunias (Ruellia caroliniensis) as a "matrix plant" and it turns out that they, along with plantains, are host plants for Common Buckeye caterpillars, along with several other species.  So, was it a coincidence to see this one last summer, a year or two after I started adding Carolina Petunias to the yard?  Or the result of adding yet another native plant species to the local plantscape?


Silver-spotted Skipper (Epargyreus clarus), 8/23/23.  If you look very closely, you can also see a little crab spider under the flowers to the right of the skipper.  The caterpillars of Silver-spotted Skippers feed on many plants in the pea family, from Wisteria to Tick-trefoils, where they build a shelter with silk.  According to iNaturalist, it's unusual to see this species visiting yellow flowers;  they prefer blue, pink, red, purple and even white blooms.


Wavy-lined Emerald Moth caterpillar (Synchlora aerata), 8/23/23.  This is the only species of butterfly or skipper (or moth) that I have seen using Hairy Elephant's Foot as a host plant.  These little guys camouflage themselves by sticking pieces of the flower they are eating to their bodies, so this one has purple bits pasted to it, but the same species will have bright yellow bits on one of the Rudbeckias, white bits on Mountain Mint, etc.  Many times, it's hard to see the caterpillar body at all!  The adult moth is a very pretty light emerald green with wavy lines, as suggested by its name.

Other butterflies that I've observed nectarting on Hairy Elephant's Foot include the Sleepy Orange (Abaeis nicippe) and the Cabbage White (Pieris rapae).  Other skippers that I've observed include Horace's Duskywing (Erynnis horatius), Common Checkered Skipper (Burnsius communis), and Zabulon Skipper (Lon zabulon).


PEST CONTROL SQUAD - SOLITARY WASPS:

Wasps seem scary to many of us, but it's literally a few "bad apples" that have spoiled the barrel of public opinion.  Social wasps (paper wasps and yellowjackets) live in colonies, which they defend vigorously.  Solitary wasps, on the other hand, build nests by themselves and are not at all aggressive.  They will only sting if you attempt to catch them in your bare hands.  I have not observed any social wasps using Hairy Elephant's Foot, but I've observed several solitary wasp species doing so.

All wasps raise their larvae (their "babies") on meat, usually on paralyzed insects, sometimes on paralyzed spiders, and (for social wasps) on chewed up insects.  Because they raise their young on other insects and on spiders, wasps are important predators in our yards and gardens, helping to keep the populations of other species in balance and under control.

Solitary wasps paralyze various species of insect or spider and then lay an egg on the paralyzed prey.   Each different species of wasp preys on a different species of insect or spider.  After being paralyzed, the prey animal lives and provides fresh food for the larva when the wasp egg hatches.  Gruesome, to my mind, but very effective.


Double-banded Scoliid Wasp (Scolia bicincta), 8/20/23.  Scoliid wasps are scarab beetle predators, digging for beetle larvae (a.k.a. grubs) in the soil, paralyzing them, and laying an egg on each.  When the egg hatches, the wasp larva eats the beetle larva, then pupates in the host body.   These wasps are excellent grub control!  About 10 years ago, when we lived in south-central Kansas, I did an entire blog post on this species:  http://gaiagarden.blogspot.com/2014/08/double-banded-scoliid-wasp.html



Blue-winged Scoliid Wasp (Scolia dubia), 8/20/23.  Isn't this a cool looking wasp?!  I had never seen this interesting looking species before last summer.  As a scoliid wasp, it is another species that preys on scarab beetle larvae (white grubs), like the Double-banded Scoliid Wasp above.  It is thought that these species may also parasitize Japanese beetle larvae!  


Gold-marked Thread-waisted Wasp (Eremnophila aureonotata), 8/21-3/23.  I've always wondered how anything - food, blood, etc. - gets through that narrow waist!  Anyway, this interesting looking solitary wasp preys on larger moth larvae, like those of the sphinx moths and owlet & cutworm moths, for food for its larvae.


Fraternal Potter Wasp (Eumenes fraternus), 8/20/23.  There's a reason this little wasp is called a "potter wasp" - the female builds a gorgeous little mud pot in which she stashes the caterpillars that she paralyzes for her young to eat.  She then lays an egg and closes the pot, also with mud, making a perfect little nursery.



Weevil Wasp (Cerceris halone), 8/23/23.  Another solitary wasp, this wasp provisions the cells in her nursery burrows with paralyzed weevils from the genus Curculio.


A PREDATOR AND PREY DUO:

There are bees known as "cuckoo bees" that parasitize the nests of other bees.  Often this happens by the cuckoo bee following the female of its host species back to her nest.  When the host female departs for another load of pollen and nectar to provision her latest brood cell, the female cuckoo bee quickly ducks in and lays an egg.  Generally, when the egg of the cuckoo bee hatches, it either attacks and kills the larva of the host bee, or it hatches first and eats the egg of the host bee before it hatches.  Either way, the cuckoo bee larva then eats the provisions that the mother host bee stored for her own offspring, pupates, and emerges the following year in place of the young of the host bee.

The relationship between the host bee and the cuckoo bee is often very specific, with each cuckoo bee parasitizing only a single species.

How does the cuckoo bee find the host bee?  Well, she hangs out at the same "bar", so to speak.  The life cycles of the host bee and the cuckoo bee are perfectly timed to overlap, and both will be found nectaring at the same flowers.  I found such a pair using the blooms of Hairy Elephant's Foot in our yard:  the Two-spotted Longhorn Bee (host) and the Lunate Longhorn-cuckoo Bee (parasite).



Two-spotted Longhorn Bee (Melissodes bimaculatus), 8/20/23 - host bee.  This almost pure black bee gets its name from the two squarish white spots on either side of its abdomen.  Unfortunately, you can't see those field marks in this photo.



Lunate Longhorn-cuckoo Bee (Triepeolus lunatus), 8/20/23 - cuckoo bee (parasite).


NATIVE BEES - POLLINATORS EXTRAORDINAIRE:

More people are understanding the importance of our native bees for pollination.  The beloved Honey Bee is actually a European import, brought here by colonists who unsurprisingly wanted the honey it produced, as well as its pollination services.  But, for all we hear about honey bees pollinating plants, they are not as efficient at the job as many of our native bees are.

Before the European colonists arrived, there was no problem with pollination in North America.  This continent has almost 4000 species of native bees, often with life cycles exquisitely timed to coincide with those of the plant they evolved to partner with.  Some of these native bees are generalist pollinators, others are specialists who only pollinate one single species, still others pollinate the flowers of just a few plants.

I have not seen honey bees use Hairy Elephant's Foot, although that certainly doesn't mean they don't.  The bees I've seen pollinating this plant all fall under the heading of generalist native bees.  I'll start with two different bumble bee species.....



American Bumble Bee (Bombus pensylvanicus), 8/23/23.  According to iNaturalist, this species used to be one of the most common types of bumble bee, especially in the south, but 90% of its population has been lost in the last 20 years.  It is now considered threatened throughout much of its range.



Common Eastern Bumble Bee (Bombus impatiens), 8/20/23.  As its name implies, this is the bumble bee that I see most commonly in our yard.



Eastern Carpenter Bee (Xylocopa virginica), 8/20/23.  What looks like a bumble bee but has a smooth abdomen?  A carpenter bee.  Great pollinators, they do NOT eat wood...although they do tunnel into it to make their solitary nests.  The females will reuse existing nest tunnels, only taking the time and energy to excavate new tunnels when absolutely necessary.



Pure Green Sweat Bee (Augochlora pura), 8/20/23.  This beautiful little bee nests in rotting logs, a habitat that we have been restoring on our property.  The fertilized females also overwinter underneath rotting logs, waiting until it's time for them to emerge in the spring.


FLIES:

Many flies act as pollinators, although they are not as well known in that role as bees are.  The first species I share here is one of the relatively rare species I've seen on Hairy Elephant's Foot.



Yellow-thighed Thick-leg Fly (Tropidia albistylum), 8/23/23.  This is a relatively rare species of syrphid fly with a very unattractive common name.  As of this writing, there are only 212 observations of this species in iNaturalist, as opposed to 25,000-50,000 observations of two more common syrphid fly species that I've seen in our yard.



Greenbottle Fly (Lucilia sp.), 8/20/23.  This genus of flies (I can't identify this photo below that level) are scavengers, generally speaking.

There were at least 2 other species of flies that I photographed on Hairy Elephant's Foot, but I was unable to identify either of them further.


PASSERSBY:

Of course, in watching any plant or area, there will be some insects that just happen to perch for a while.  Rounding out this line-up of Hairy Elephant's Foot insect fans are a couple of those more incidental visitors....



Blue Dasher (Pachydiplax longipennis), 8/22/23.  This is a dimorphic species, meaning that the male and female look dissimilar.  This individual is a female;  it is the male that has the blue coloration for which the species is named.  Dragonflies are fierce predators of smaller insects.  I'm always hoping the ones I see are living up to their colloquial name of "mosquito hawks".



Eastern Tailed Blue butterflies (Cupido comyntas)  - and a Midge (7/30/23).   Hairy Elephant's Foot can even be used for a bit of canoodling, with or without a voyeuristic midge looking on.

In conclusion, Hairy Elephant's Foot is not a classically "beautiful" plant, but it sure packs a powerful punch for wildlife.  Including insects I've seen but not photographed, I've noticed over 30 different species using this plant - and the deer don't bother it at all.  If you can find a corner somewhere, I highly recommend it.  I've never seen Hairy Elephant's Foot "in the trade", but personal experience tells me that it transplants well.  Mine just showed up on their own.  Keep your eyes peeled or ask if anyone you know has some they'd be willing to share.  You'll be glad you did.

A Recent Cast of Characters in My Gardens: Pollinators and Predators

With the initiation of several days of rain, it seems like a good time to share a few garden photos from the plethora I've taken over the last few weeks.  Since I'm obsessed with pollinators and other wildlife, that's what I'll generally be showing you!

Gaillardia (Gaillardia pulchella) brings in a lot of insect activity.  I have several pots of gaillardia on our back patio, as well as a few plants along the street by our mailbox.  Not surprisingly, most of my photos are from the plants I see most often - the ones near my back door.

This is a lousy photo, but I wanted to share the single bumble bee (Bombus sp.) I've seen in my gardens so far this summer.  Gaillardia is the ONLY flower I've seen her on so far.

A female monarch (Danaus plexippus) finally visited the yard for several days last week and she left several eggs behind.  Here's she's ovipositing on a swamp milkweed (Asclepias incarnata) I planted a couple months ago.  I'm a "survival of the fittest" biologist, so I don't collect the eggs and raise the caterpillars inside;  I'm waiting to see if I see any caterpillars - this photo was taken on the 28th, so there should be a couple tiny babies out there munching away, but I haven't gone looking yet.  (Update:  my grandson and I went out in the rain this afternoon and found at least 3 tiny new monarch caterpillars!  Yeah!)

Ms. Blue Dasher (Pachydiplax longipennis) here isn't a pollinator, but I love welcoming her and her relatives into the yard.  Every mosquito this mosquito hawk eats is a mosquito that doesn't bite me! Aren't her eyes particularly gorgeous?  The body of the male blue dasher is a beautiful powdery blue, but I've been seeing almost exclusively females lately.

This green treefrog (Hyla cinerea) seems to have decided that the outside corner of our gutter near the bright lights of the kitchen window makes a perfect home.  Over the past week, I've been seeing her (him?) frequently within just a few inches of this location.   Note:  nothing like a closeup photo to let you know the house badly needs a power washing!

Out front, the newly planted sweet pepperbush (Clethra alnifolia) has excited a lot of pollinator interest.  I shared the potter wasp and the 4 spotted scarab hunter wasp I've seen nectaring here in my recent post;  this is a carpenter-mimic leaf-cutter bee (Megachile xylocopoides) who also has seemed to enjoy the blooms. 

The deep velvet black of this bee's body and the iridescent blue-black of its wings are just stunning.  I wonder if this is the species that has been harvesting circles of dogwood leaves to make their nest cells waterproof?

Another little green treefrog was tucked away inside a Flyr's nemesis (Brickellia cordifolia), hoping against hope that I didn't actually see him as I looked around.  I let him pretend that I hadn't noticed him.....

With the spotted beebalm (Monarda punctata) beginning to bloom, I'm starting to see a little more activity in that section of the garden, including this small green anole (Anolis carolinensis).  I'm still not seeing many insects attracted to the spotted beebalm blossoms, but I did see a hummingbird feeding - even though I didn't have my camera with me so I could visually share with you.

Back to the anole for a moment, I've been seeing many tiny little green anoles for the last several weeks, which just makes me smile.  Obviously it's been a good year for anole love!

Another recent dragonfly visitor was the great blue skimmer (Libellula vibrans), who perched on top of the poles in our tomato pots for a while - and was lucky enough (and good enough) to capture a passing moth shortly after I took the top photo.  Those big, black-spotted blue eyes aren't just for show!

Out front, enjoying the turkey tangle fogfruit (Phyla nodiflora), there's been the phaon crescent (Phyciodes phaon), nectaring - and possibly laying eggs, since fogfruit is their larval plant.  Note:  I don't know if this individual is a male or female.

The fogfruit has also attracted many other insects, including a female blue dasher dragonfly, a carpenter-mimic leaf-cutter bee, several  different species of wasps, bees, and flies.  In fact, the fogfruit is active enough that it's probably worth a post just by itself.  I just wish it looked a little more "gardeny"....

Anoles have been out in the front gardens as well as in the back.  Here was one haunting a summer phlox (Phlox paniculata) blossom.  Sometimes I wonder if I don't see huge numbers of pollinators because I DO see lots and lots of predators around the blooms - and I'm sure it's not a coincidence that they are hanging out there!

Speaking of predators, whether nymphs (like this one) or adults, I'm seeing quite a few milkweed assassin bugs (Zelus longipes) this summer.  I thought they were so-named because they were part of the milkweed community, but recent reading suggests their name comes from their coloration.  I've certainly seen them on many, many plants, not just on milkweed.

The clustered mountain mint (Pycnanthemum muticum) in the back yard has brought in quite a few unusual (for my garden) pollinators.  Besides several wasp species, there is this grapeleaf skeletonizer moth (Harrisina americana) which has both a common name and a color pattern that make it a perfect Halloween animal.

Believe it or not, this small, colorful, Halloween themed moth, also nectaring on the mountain mint, is from the a group of moths known as bird dropping moths.  Yes, that's an actual common name for moths in the subfamily Acontiinae .  This moth goes by the hard-to-remember name of black-dotted spragueia moth (Spragueia onagrus)  and is an animal I've never seen before in my life.  Kudos to the helpful folks at BugGuide.net for helping me identify this one!

Lacewing larvae, looking for all the world like prehistoric monsters or like some less glittery version of Tamatoa, the Crab, on Moana, are hard to see unless you look closely, but they are great allies in garden pest control.  This photo is blurry (the entire "mound" is barely 1/4" across and I wasn't using a tripod) but, if you look carefully, you can see the huge jaws under the front edge as well as a wing from one of its dinners right above the jaws.

In all, this lineup of characters from my garden highlights 6 garden predators (green anole, green treefrog, milkweed assassin bug, lacewing larva, blue dasher dragonfly, great blue skimmer dragonfly) and 6 pollinators (monarch, bumblebee, carpenter-mimic  leaf-cutter bee, phaon crescent butterfly, grapevine skeletonizer moth, and black-spotted spragueia moth).  During the 10 days that I photographed these animals, I saw many other animals, too.  Some, like the 5 species of wasps that I talked about in my last post, I've shared with you.  Others, like bluebirds, cardinals, bluejays, gray squirrels, chickadees, tufted titmice, house finch, mockingbirds, red-shouldered hawk, brown skinks, southern toads, and Eastern box turtle, I haven't shared.

How can anyone be happy with a statically "pretty" landscape, when a garden filled with wildlife changes minute by minute?!  I love the surprise of going out into my yard and meeting a new insect neighbor.  I love the pleasure of looking at a flower cluster and realizing that I'm looking into the eyes of a little lizard or camouflaged frog.  Each new animal I see adds a layer of richness to the world around me that delights and soothes me.  What an honor to be sharing my yard and gardens with all these other forms of life here on Earth.

A Trickle of Native Insects Begins to Appear....

FINALLY!  We've lived here for about 16 months now and at last I am beginning to see a greater variety of  insects attracted to and living in our yard.  It's so exciting to go outside and see native pollinators nectaring at the few little blooms we have scattered around, or predatory insects patrolling the foliage and flowers.  It sure goes to show that changes don't have to be big or dramatic to have an impact.  Every little bit counts.

So here are some of my recent finds....






Gulf fritillaries (Agraulis vanillae) are gorgeous butterflies, with silver patterns on the undersides of their wings and an almost fluorescent orange coloration on the top side.  The fresh individual in the top photo was nectaring at garden phlox (Phlox paniculata), while the tattered one in the lower photo is nectarying at Flyr's Nemesis (Brickellia cordifolia), a rare wildflower in Florida that has recently become available at some native plant nurseries, including 7 Pines Native Plant Nursery in DeFuniak Springs.


Out and about, I'm seeing more gulf fritillaries flying everywhere these days, presumably due to the time of year.  However, I'm starting to count on seeing them regularly in our yard since we finally have some caterpillars eating the maypop vines (Passiflora incarnata) that we planted on the lower terraces last spring.  Just as monarch caterpillars only eat milkweeds, plants in the genus Asclepias, so gulf fritillary caterpillars only eat maypops and passionflowers, plants in the genus Passiflora.

Predators are pretty rare in the yard still.  It took me around 5 years to start noticing them regularly in my Kansas gardens, so I'm trusting that they'll increase in number as I garden naturally here.

With a lake right out the back door, however, we do have several dragonfly and damselfly species.  One of the species I've just started to see is the eastern amberwing (Perithemis tenera).  A male and a female have staked out the small patch of powderpuff (Mimosa strigillosa) in the front yard and I can count on finding them there essentially every day.



Although this species is quite small for a dragonfly, the male eastern amberwing, shown above, is easy to spot since he's dramatically colored, with shining amber-colored wings and a darker amber body.  Up close, the camera captures yellow markings on the thorax and abdomen that the eye generally misses.  The female, however, is much different....

...and much drabber.  Her darkly blotched wings and more sober colors don't attract the eye as her mate's colors do, but that's probably the point.  She, too, has yellow markings on her thorax and abdomen. 

These small dragonflies are said to eat "tiny, flying insects", which I interpret to mean mosquitoes.  Hopefully my male and female eastern amberwings will produce lots and lots of baby eastern amberwings to patrol my yard even more thoroughly!

Another colorful species that I've observed, photographed, and been able to identify is the metallic green bee, Agapostemon splendens.  I've always loved the metallic green bees, especially the ones that are entirely green, because of their vibrant coloring.

Shown above, the females of Agapostemon splendens are especially beautiful to my eye and earn their "splendid" moniker based on the beautiful shadings of blue and green on their abdomen.  Note:  I have no real idea why this species was labeled the splendid green metallic bee, but I think the abdomenal color IS splendid.

Here's another, closer look at that gorgeous color.  Look, too, at the pollen load that this little bee is carrying - the pollen from this species of flower is white, not yellow, and that's a LOT of pollen clustered on her hind legs!  She still has to finish her load and, most importantly, fly back to her nest with her carefully gathered provisions.  Like many other native bees, the Agapostemon bees nest in the ground, usually in a tunnel dug by the female.  After digging the tunnel, the female gathers together a ball of pollen and nectar, lays an egg on it, seals off the cell, and repeats the process several times.

Interestingly, like the eastern amberwing dragonfly above, Agapostemon splendens is another dimorphic insect species, with the male looking significantly different from the female.  The photo above is a male of the same species.  While the thorax is similar to the female's, the abdomen is completely different - males sporting a natty black and yellow stripe pattern that is vibrant, but not as pleasing to my eye.  This little guy was fun to watch.  He seemed to perform head stands as he fed, diving deeply into the flower to get his prize.

Unlike the colorful green metallic bees, the next bees I want to share with you are somber black with a few white markings.

Another native bee, this is a carpenter-mimic cuckoo-leaf-cutter (Coelioxys dolichos) - a name that seems more interesting than the bee looks, at least on first appraisal.  That's the bloom of a wild lettuce (Lactuca sp.) that she's feeding on.

What drew my attention to this bee was the pointed abdomen, which is very distinctive.  Cuckoo bees are parasites on other bees.  The females of this genus of cuckoo bee, Coelioxys, use that sharp abdomen to break into the nests of their host species and lay eggs on the pollen and nectar stored there for the host's eggs.  Because female cuckoo bees don't have to provision their own nests, they don't have pollen baskets and they aren't seen carrying pollen;  they do, however, still have to feed themselves.

This particular species, the carpenter-mimic cuckoo-leaf-cutter, is a parasite on a single bee species called the carpenter-mimic leaf-cutter bee (Megachile xylocopoides). Ironically, when I went to look up M. xylocopoides, I recognized the pictures as showing the same species as another, unidentified bee species in my recent photos!  I even took the photos of the two different species within a few feet of each other, just 1 day apart!

Here is the male carpenter-mimic leaf-cutter bee (Megachile xylocopoides), also feeding on wild lettuce blooms.  Did the two bees, the predator and the prey, hatch out of the same nest?  There's probably a good chance of it.  At the very least, it would appear that the nests were nearby.

There are many more sightings I'd love to share, but this post is long enough for now.  Hope you're seeing lots of interesting insects in your gardens, too!
