What appears to be a flower here is actually a group of caterpillars working their way down a sapling trunk.
They look like they could do a decent job sharpening a pencil, about the same width as this tree(?) trunk.
Despite the black background, this was taken a few hours before sunset. At the time there was probably a few feet of the trunk left. I marked the location and returned after dark. I found no trace of the trunk or the caterpillars. They apparently ate the whole tree.
I know there are defoliating caterpillars. I know there are wood boring caterpillars. I never imagined there are caterpillars that consume an entire tree though. That’s assuming they eat leaves, which I didn’t observe.
Being National Moth Week, I have every excuse to post about one of my favorite subjects. Admittedly, I get more excited about caterpillars, but I enjoy seeing the moths that most of them become.
Back at the end of April, I was distracted by something while going to check the mailbox. Actually, I’m often distracted any time I venture into my yard, but that’s kind of the point of having one for me. Anyway, some large hollies form a hedge along part of my driveway. I spotted a caterpillar dropping from from the holly to the ivy beneath it. I grabbed it for a closer look and started scanning the holly for others. I quickly found another one and brought them inside for rearing. Less than a month later, I was rewarded with a Black-Dotted Ruddy, Ilecta intractata.
This was one of the last caterpillars I collected last year for rearing. I generally stop looking around the end of October.
This particular caterpillar is fairly distinct and easily recognized as Schizura ipomoeae. The stripes on the head capsule are diagnostic.
The adult on the other hand is more difficult to recognize, I think. I’d have probably given up identifying it if I didn’t already know what it was based on the caterpillar. This particular one emerged in early May.
You might have noticed I haven’t posted anything in awhile. I get a lot of enjoyment from posting here, and I remain committed to doing so whenever possible. Lately it just hasn’t been a priority for many reasons. Hopefully, I’ll now be able to get back to posting more regularly.
For many years I’ve noticed colorful little caterpillars that live individually in silken retreats on the surface of leaves of poison ivy. At a recent BugGuide gathering, a photo of one of these caterpillars was shown and I realized we still didn’t know what these were. I resolved then to rear a few to try and arrive at an identification. There’s plenty of poison ivy near my home, so I didn’t anticipate much trouble finding a few.
Here’s the first one I found. The white area just behind the head is atypical. The caterpillar is smaller than usual, so it might be an early instar. It could also represent some sort of injury.
Even though I can’t identify it, it’s pretty enough that I had to post it.
Earlier this month I was checking for anything interesting in my backyard when I came across this caterpillar in a rolled up leaf on viburnum. I decided to try and rear it to get an identification.
It turns out it was a final instar because it pupated beneath its leaf within a week, sometime around the 9th.
I removed the pupa from its webbing for some cleaner shots.
I checked daily for the adult, but sadly it eclosed while I was away on vacation, sometime around the 20th give or take a few days. When I got back I found a dead and beat up adult. I prefer live images of a fresh adult that I can release later, but I’ll take what I can get here I guess.
This colorful moth in the family Arctiidae looks a little worse for wear. Nonetheless, it’s quite striking and I’m sure a fresh specimen must be even more so. I later saw another one of these near a porch light so it might be a common species.
While searching for a possible identification, I came across this blog posting. It describes how hundreds of caterpillars were invading people’s home in Piracicaba, São Paulo. With the help of a biologist, they found both the host plant and some pupae for rearing. What emerged looks very much like the moth above, identified as Cosmosoma teuthras, a common moth throughout Brazil. Check the site for photos of the caterpillars, pupae, and an adult. I have no idea if there are similar looking species, but it seems like a good possibility for what I found.
No one commented on the latest identification challenge. Despite showing just the tip of the forewing, the image provided showed the distinctive feature of a subfamily of moths commonly called hooktip moths. If you got that far, it’s a pretty simple process of elimination since there are only a handful of North American species, each one easily distinguished from the other. This species is the Arched Hooktip, Drepana arcuata.
This individual appears to be a male, based on the widely bipectinate antennae.
Today I found my first moth in the overwintering container I keep outside. Can you identify it from this wing fragment? I’ll keep the comments hidden for awhile, but this should be an easy one.
This cryptically colored little caterpillar reminds me of lichen moth larvae I’ve seen closer to home (Family Arctiidae, subfamily Lithosiinae). If so, it’s in the right place!
