Poison Ivy Caterpillar / Dimorphic Macalla Moth
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.

Wild Goat
April 23, 2012 | Arikok National Park, Aruba
I took a short trip to Aruba recently. Late in the trip, I spent a half day in Arikok National Park. I saw plenty of wild goats. There are reportedly wild donkeys as well, but I didn’t see any of those.

Another Unidentified Caterpillar
~30mm | January 7, 2012 | Tupaciguara, Minas Gerais, Brazil
Even though I can’t identify it, it’s pretty enough that I had to post it.

Leafrolling Mystery Caterpillar
20mm | April 5, 2012 | Twelvestones, Roswell, GA, USA
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.

Membracis Treehoppers and Nymphs
~10mm | January 7, 2012 | Tupaciguara, Minas Gerais, Brazil
When I spotted a group of treehoppers like the one above, I settled in for a while. With such a beautiful subject, I was determined to get some good photos. The shot above is probably my favorite out of around 300 or so shots. I struggled to get something in the background to avoid the usual black background that usually happens with macro flash photos. A black background wasn’t going to serve very well for these mostly black treehoppers.
Not only are the adults pretty, but the nymphs are also attractive in their own way. I prefer the black background here.

Clearwing Moth
~20mm wide | December 31, 2011 | Quirinópolis, Goiás, Brazil
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.

Identification Challenge #14 Reveal: Arched Hooktip
27mm wide | March 24, 2012 | Twelvestones, Roswell, GA, USA
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.

Identification Challenge #14
March 24, 2012 | Twelvestones, Roswell, GA, USA
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.

More Ants and Scales
5mm long | July 8, 2011 | Victorio Siqueroli Park, Uberlandia, Minas Gerais, Brazil
Besides the turtle ants, there was one other type of ant crawling around in the same area. They were quite aggressive, often taking a threatening stance with their gaster turned down and under their body. The one above seems to be saying, “Back! This scale is mine”. The scale above, by the way, differs from the ones I posted about earlier.
Forager?
The ants above were fairly active. The one below, however, never moved from the spot I found it. While I assume it’s the same species, it has a slightly different body build. Note, for example, how much wider the head is. Maybe it’s a soldier?
