Turkey Tangle Fogfruit Community

Certain plants seem to create large communities of insects and other wildlife within my garden.  I thought I'd do a series on a couple of these species, starting with Turkey Tangle Fogfruit (Phyla nodiflora).  As I've gone through my photos from last year, I realized I've got pictures from at least 23 different species of animals using this species in 2018 alone - and that's just the number I captured with my camera.  I know there were animals using it that I wasn't able to capture on film (like swallowtail butterflies).  I'm equally certain there were animals using it that I simply didn't see.

Fogfruit is not a showy species to my eye.  Although some people really like its dainty flowers, to be honest, I find this plant rather blah visually.  It is, however, a powerhouse for supporting pollinators and other insects and, as such, has earned a place in my yard whenever possible.

Essentially a groundcover, fogfruit grows around 8" tall.  About 3 years ago, I started out with 2 plants in gallon containers, planted 2' apart.  The fogfruit now covers an area that is about 6' X 8' - and it would be happy to be out in the driveway and into the street, too, if we didn't keep it trimmed back.  On the plus side, fogfruit manages to hold its space fairly well, once established, and doesn't need much of any care.

The first photos I have of the animals it harbored last year are from mid-May.

Here is a small spider that I saw on May 15th, then didn't see again all year.  It's a pretty little thing which the great folks at Antman's Hill on Facebook helped me to identify as an orbweaver, Gea heptagon.

On the same day, I captured a photo of this little syrphid fly (Toxomerus sp.) nectaring at one of the fogfruit blossoms.

Like others in this genus, the larvae of this fly feed on aphids, thrips, and small caterpillars throughout the garden, so it's nice to see the adult visiting.

By June 10th, the action was heating up.  There was this cute little orange "teddy bear" nectaring, a bee fly (Chrysanthrax cypris).

Cute as this guy is, its life cycle is less cuddly.  Flies in the Chrysanthrax genus are external parasitoids on the cocoons of some solitary bees and on the cocoons of tiphiid wasps, which are themselves predators of beetle larvae.  The "balance of nature" is sometimes hard for me to feel comfortable with and gracefully accept, but I do my best.

Throughout June and again in August, I have photos of another bee fly (Exoprosopa fascipennis) nectaring at the fogfruit.

Again, I find this an attractive little creature, but again its life cycle is rather fearsome.  The bee flies in Exoprosopa feed on the cocoons of many different kinds of wasps, including the tiphiid wasps mentioned above, spider wasps, and a group of solitary wasps known as sphecid wasps.

Speaking of wasps, in mid June, this scoliid wasp (Scolia nobilitata) was enjoying the fogfruit nectar, too.

Scoliid wasps are parasitoids of beetle grubs, especially the grubs of May beetles.  The females dig down to the grub, sting it to paralyze it, and deposit on egg. When the egg hatches, the wasp larva eats the perfectly preserved beetle grub.  I like my grub control to be natural (even if it is rather gruesome that way)!

Since both the bee flies and the scoliid wasp were nectaring at the same time on the same plant, it is possible that one or the other of the bee fly species parasitizes this scoliid wasp species, following females as they leave their feeding ground and search for beetle grubs to parasitize.  There is so much about these little guys that we simply don't know, even things as basic as which bee fly species parasitizes which wasp species.  Often these predator/prey relationships with parasitoids are very specific, confined to just one or two species, or perhaps between two particular genuses.

Moving back to less gory lifecycles, a couple days after photographing the pretty wasp above, I started capturing images of butterflies and skippers.  First was this Fiery Skipper (Hylephila phyleus) on June 16th.

 Since the larvae of fiery skippers dine on grasses such as St. Augustine, this species is relatively common.

On June 22nd, I photographed the first Phaon Crescent (Phyciodes phaon) of the year, although these photos are from later in the summer.



These cute little orange butterflies utilize fogfruit as their larval plant, as well as obviously nectaring on it.  Since I see quite a few of them, I'm pretty sure that my little patch of fogfruit is producing phaon crescents, but I've never actutally found one of the caterpillars.

Something sure likes to eat the fogfruit leaves, though!

I spotted this dainty damselfly hanging out around the fogfruit several times last summer. It's the only damselfly or dragonfly species that I photographed on the fogfruit last year, and the folks at Antman's Hill identified it for me as a male Rambur's Forktail (Ischnura ramburii).  That makes sense, as I've seen the (orange) female Rambur's Forktail in the yard multiple times, although I've never photographed one on the fogfruit.

There were several more wasps and bees over the course of the summer, including this potter or mason wasp on July 20th, .....

...and this paper wasp (Polistes metricus) on August 10th.

I actually don't see many paper wasps in the yard - which is fine with me.  Instead, I see lots of solitary wasps, who are generally much easier to share space with. 

One of my favorite finds was this cute little black leafcutter bee, the Carpenter Mimic Leafcutter Bee (Megachile xylocopoides).  As the name suggests, this stunning black bee with the fluorescent blue shimmer is considered a mimic of larger carpenter bees, specifically the Southern Carpenter Bee, which I also saw in my yard last summer.

Note the long hairs on the underside of the abdomen?  That's how you can tell it's a leafcutter bee - at least if it's a female.  Female leafcutter bees carry pollen in those hairs, often giving them a potbellied appearance.  This gal was apparently feeding herself, not gathering pollen for future offspring.

On August 8th, I was able to capture photos of a Barred Sulfur (Eurema daira) visiting...


...and if you look closely at the stem a few inches below the blossom, you'll see the wad of spittle that signifies a spittlebug nymph feeding - yet another insect species utilizing the fogfruit.

A few days later, I photographed this crisp Checkered Skipper (Pyrgus sp.).


Apparently, most skipper larvae fold and sew leaves together to make tent shelters for themselves, so don't be too quick to destroy any such structures you might come across in your garden.

Of the 23 species I photographed on my Turkey Tangle Fogfruit in 2018, the above photos were the most interesting and/or the insects were the most photogenic.  Rounding out my 23 species were 4 more species of flies, 2-3 species of small beetles, a honeybee, and two other bees I haven't been able to identify yet.

Like the plant they were visiting, most of these animals aren't large or particularly beautiful.  They are the everyday denizens of our gardens, busily living their lives and often feeding other animals in the process.  To me, each of these species has the right to exist, the right to its place on this Earth, just as much as any other species has that same right.  I hope that, someday soon, we humans can learn to coexist with the other plants and animals on this planet, instead of needlessly and carelessly destroying them.

Learning My Garden Through Weeding

Anybody else out there enjoy weeding?

While I don't like to be outside for any length of time if the weather is abysmal - which is how I define most of the hot, humid summer down here in the panhandle of Florida - once the weather starts cooling off, I actually find that I like to weed.  It's meditative...and I learn A LOT about the nuts and bolts of daily life going on at ground level in my garden.

My latest weeding project is/was a large, new bed that I halfheartedly started last spring, before I got chased inside by heat and humidity.  The photo above shows about half of the area, which continues on to the right another 10 feet or so.  Taken fairly early in the weeding process, this shows the approximate height and thickness of the weeds I was removing. 

I chose to hand weed this new bed for two basic reasons, one of them related to poor planning.  First of all, I knew there were several small seedling plants located in the area that I wanted to save and, probably, relocate.  Secondly, when I started to make the bed last spring, I put in a few plants that I didn't want to lose.  There were 3 clumps of pink rain lilies (Zephyranthes grandiflora) and, more problematically, several wild strawberry plants (Fragaria virginiana) that had spent the summer putting out runners and baby plants.  If I smothered the area with newspaper and mulch, it would be relatively easy, but I'd lose ALL of the plants in the area, including the ones I wanted to keep.

So I sat down on my rear and I weeded.  The weeds were primarily a mix of an 18" tall, rather airy plant with wiry stems that I haven't identified, doveweed (Murdannia nudiflora), chamberbitters (Phyllanthus urinaria, a.k.a. gripeweed, for my Mobile friends), Asiatic hawksbeard (Youngia japonica), mock strawberry (Duchesnea  indica), Florida pusley (Richardia scabra), and Virginia buttonweed (Diodia virginiana).  For seasoning, there was a little bit of dollarweed (Hydrocotyle umbellata), the dainty Carolina ponysfoot (Dichondra carolinensis), and a variety of sedges (Carex spp.) thrown in.

The photo above is a single stem of Virginia buttonweed, surrounded by lots of doveweed.  Lovely, isn't it?  (Yes, that's sarcasm.)  At least it was mostly green.  Anyway, of all the weeds, only about half the species were native:  Virginia buttonweed, Florida pusley, dollarweed, Carolina ponysfoot, and probably most of the sedges.  I don't know about the unidentified, 18" "wiry" weed.  Most of the biomass was doveweed, the wiry unknown, and Virginia buttonweed.

Anyway, as I sat there on the ground, hour after hour, I not only got to know the plants quite well, but I also got to see some of the "denizens of the dirt", those little creatures who live their entire lives in our gardens but that we rarely see or notice.  A few of these little creatures sat still long enough for me to photograph, so I thought I'd share them with you....

First off, I am going to cheat just a little.  I saw one skink in this area as I was working, but I didn't get a photograph of that particular individual.  I did get a photo of another one of the same species a few days earlier, so I'll share the photo that I have.

This is a ground skink (Scincella lateralis) and it was probably about 5" long, which is about as large as ground skinks get.  Apparently they are the commonest skink in Florida gardens, but they are rather hard to see, as they move very rapidly through the undergrowth and leaf litter.  When I am working in an established bed, I often catch a glimpse of a little brown lizard skittering away.  I assume those are other ground skinks, exhibiting their getaway skills.

A toad was the only other vertebrate that I flushed out as I weeded, although certainly birds and other vertebrates must have foraged in the area from time to time.  This little guy...





...seemed to be missing his right rear leg.  An injury?  Some sort of genetic defect?  Hard to tell.  Surprisingly to me, there are only 4 species of toads in Florida.  I think this is a southern toad (Bufo terrestris), the most common species, but I am not completely certain.


Rather unexpectedly, there were two large caterpillars amidst this unprepossessing mass of vegetation.  The first one was an odd looking "woolly bear" type, with coal black hair and bright red segments that showed when it curled up in its defensive position.  I've seen lots of woolly bears before, but never one colored like this.

According to BugGuide, this is the caterpillar for the giant leopard moth (Hypercompe scribonia).  I've never seen an adult, but the BugGuide photos look stunning and I will certainly be looking for one now that I know it obviously occurs in our yard.

The second large caterpillar fell out of a handful of weeds that I had pulled, but by observing it for a couple minutes as it got back to eating, I believe it was munching determinedly on Virginia buttonwood.

Despite this guy's 3-4 inch long size and distinctive markings, he was a little hard to identify.  Nothing seemed to fit when I scanned the hornworm photos at BugGuide, so I eventually turned to Caterpillars of Eastern North America, by David L. Wagner, where I was able to figure out what I was seeing.  This is the caterpillar of the Tersa Sphinx (Xylophanes tersa), another striking moth species that I've never seen before.  The link is to the node at BugGuide, where you can see photos of both the caterpillars and the adults.

I photographed two other caterpillars, both much smaller.  One was a hairy individual that I haven't tried to identify yet....

while the other was an early instar of yet another sphinx moth, about an inch long, also currently unidentified.

There were lots of little, round snails, maybe 1/4" in diameter...

...and one large, conical snail whose shell was at least an inch in length.





While I saw many green stinkbug nymphs, I only saw this one adult stinkbug.


While I'm not completely sure, I think this is Euschistus crenator, a species that feeds on sedges.  Probably the green nymphs were of a different species.

There were several small, longhorned grasshoppers, ....

but no shorthorned grasshoppers of any size, which is a major change from gardening in Kansas.

There were also a lot of small spiders.  I only took the time to photograph this one, which was slightly larger than most.  I think it is a wolf spider, but I don't know the species yet.

Last, but hardly least, there were a lot of roaches running around.  I didn't try to photograph any of them, assuming they were wood roaches which help to decompose organic matter.  I saw this one, though, that was different and obviously an adult.  It was trying to get away through the grass and "posing", so I did take a couple minutes to get a few photos.  Imagine my dismay just now as I worked to identify it and realized it is probably a non-native, Surinam Cockroach (Pycnoscelus surinamensis) .  If so, according to BugGuide, it has the interesting characteristic of reproducing entirely by parthenogenesis in the U.S. - no males have ever been found.

As I worked and noted all of the small creatures living among the weeds I was pulling out, I found myself feeling guilty for destroying the habitat that was obviously providing food and shelter for such a large variety of little animals.  I'm trying to placate myself by remembering that I will be planting a variety of native perennials and shrubs in the area this fall, all tucked in with a nice layer of leaf and wood chip mulch...but the dismay is still there, simmering in the background.  Forgive me, little ones.  I really AM trying to create a healthy habitat for all in our yard and gardens.

Pollinators and Other Creatures in the Garden

For the first time in quite a while, I was able to slip outside and take a few photos in the yard and gardens yesterday.  I didn't get great shots and I haven't had time to identify the animals, mainly insects, that I found, but I thought you might enjoy seeing them anyway.

I thought I was off to a great start when I found this black-winged damselfly as soon as I stepped off the back patio.  He was resting on a leaf of blue-eyed grass.

While I was taking the damselfly's photo, I noticed movement on the ground, in the verbena, about 2' away.  Doing some minor poking around, I was able to get a quick shot of this good-sized wolf spider lurking in the vegetation.

Next I walked around to the mailbox area, with its gay skirt of blooming gaillardia and butterfly milkweed.  Over the last month, I've seen more pollinators in this little 6 square foot area than in the rest of the yard combined, I think.  This little bee was busily gathering pollen from the gaillardia.

After the bee flew off, at first I didn't see any other action, then I noticed a colorful wasp hanging around.  This photo is rather blurry, but I wanted to show the overall markings of this gal...

...before I shared my favorite shot, which shows how her big, compound eye curves around the base of the antenna on her face.


Isn't that an amazing detail?!



Last of all, I found several insects on the aquatic milkweed (Asclepias perennis), despite its diminutive size and somewhat anemic appearance so far in my garden.  Truthfully, I only really noticed ONE insect at first - this small, dark bee....


...but note the ants that were also on the flowers.  I didn't see them until I downloaded the photo and magnified it. There was also a tiny fly hanging around, but I didn't get a clear enough photo of that one to share.

So that, fellow gardeners, completes the portfolio of "Pollinators & Others" that I found during my 25 minute walkabout yesterday afternoon.  I was a little disappointed not to find more insect life, but it's early days/months/years in my gardens here, so I guess it's not too surprising that the diversity is minimal.  I'm hearing, too, that insect life is on a major decline throughout the country, so maybe my quiet yard is just indicative of a larger problem.

Time will tell.  Meanwhile, I'm doing what I can, where I can - and enjoying the rewards that I am given.  I'll just hope to see more on another day.

Learning the Local Native Plants

Ashamedly, I have to admit that it took me living here for over 10 months to get off my duff and go back out to the nearby wild area for a walk-about to look for native plants.  Even then, my friend Anna had to initiate the outing.  I can't believe I waited this long - and I'm kicking myself about all the interesting sights I have been missing.

On Monday morning, Anna and I sallied forth to the same road/trail that my family and I visited 18 months ago.  I blogged about our finds in "We're Not in Kansas Any More!" as well as two subsequent posts about specific plants.  Walking on Monday, I actually recognized the American holly tree that I talked about in that original post, but otherwise my attention was generally drawn to very different plants this time.

We were scouting for lupine, which Anna had seen along this sand road just a week or two earlier.  Unfortunately, in the intervening time, some "maintenance" had been done on the trail by a bulldozer, carelessly and messily widening it, and we found no trace of the lupine.  We did, however, discover some other treasures.

One of the first plants we noticed was Pinewoods Milkweed, Asclepias humistrata.

This plant is also known by the common names of sandhill milkweed, for its preferred habitat, and pink-veined milkweed or purple milkweed for rather obvious reasons.  This is a plant that I would love to grow in my yard, as I find the leaves gorgeous just by themselves. 

Add in the attractive pinkish flowers and its function as food for monarch caterpillars and this plant becomes almost irresistible.

Another attractive plant that we noticed was this little white-flowered beauty with its beautifully shaped, dark green leaves.

As I researched to figure out what we were seeing, I was very glad that we didn't try to pick any of the flowers we saw, just to save us from picking this one.  This plant is called Tread-Softly, Cnidoscolus stimulosus, and all of the green, above-ground parts of the plant are covered with stinging hairs.  While this isn't not a true nettle, it is sometimes called bull nettle or spurge nettle.  Another name for it is finger rot, which makes my imagination run wild in all sorts of nasty ways.  Needless to say, this is NOT a plant that I plan on trying to import into our yard!   Ironically, at least one source said that the tuberous roots are edible...but getting to those roots might take some serious caution.

Silphium is a genus that I became somewhat familiar with on the prairie, where one of its most famous members is Compass Plant, Silphium laciniatum.  As soon as I saw the leaves of this basal rosette, my mind yelled, "Silphium!", and I think that instinctive reaction is probably correct.

While I won't know for sure until later in the year when I see it bloom, I think this beautiful little clump of big, bright green leaves belongs to Kidneyleaf Rosinweed, Silphium compositum.   I'm not sure you could dream up a much uglier name for a plant.  Despite its ugly name, I hope to find a source for this species, since I think the leaves would look really nice in a native flower bed, adding some dramatic size and visual texture to the overall mix.

There were two flowers that we found that I haven't been able to identify yet.  First was this pinky-purple little beauty.

That's reindeer moss nestled beside it, to give you a sense of scale.  We saw several of these plants blooming and they were all less than 12" tall.

Second was this yellow-green, almost abstract bloomer that I suspect is in the Euphorbiaceae family. We saw several;  they seemed to run about 15-18" tall.

If anyone knows the identity of either of these plants, I would love to know what they are.

Another plant we noticed was this silvery, quiet-looking plant.

A little research gave me the identity, Healing Croton, Croton argyranthemus

What I haven't been able to determine is why it's been given the common name of Healing Croton.  It is the larval food for a pretty little butterfly known as a goatweed leafwing.   I haven't seen a goatweed leafwing since moving here to Florida, although they do occur here, but here are photos of one in Kansas, taken in September 2013.

Speaking of butterflies, at one point we found this large chrysalis hanging from a bare branch.  I don't know enough about such things to begin to guess what species made this chrysalis, but I think it's cool.

Another insect sighting was this black and white wasp, working busily to deal with a caterpillar, presumably extracted from this stitched together clump of leaves.

At the time, I was concerned that it might be a bald-faced hornet, so I didn't get too close. 

When I got home and downloaded the photos, I realized that this little beauty is actually a potter or mason wasp, a solitary wasp, presumably collecting caterpillars to paralyze and store for its young to eat as it grows.

Reindeer moss, sparkleberry, blooming yaupon, black cherry, beach rosemary.....  We saw a lot of other things that entranced us.  I'll leave you with a photo of the sky through the pine trees - a slice of heaven.
