Fruit Fly

Posted on September 2, 2011 by Troy Bartlett

8mm | July 9, 2011 | Tupaciguara, Minas Gerais, Brazil

I start with low expectations whenever I try to identify a fly. I’m happy if I get to family, but I think I got as far as genus on this one. This female fruit fly in the family Tephritidae might be an Anastrepha species.

Crooked Jaw Termites

Posted on August 28, 2011 by Troy Bartlett

5-10mm | July 3, 2011 | Tupaciguara, Minas Gerais, Brazil

As promised in my last post, here are some termites where the soldiers are much larger than the workers. Large is relative though, since although they are twice the size of the workers, these soldiers still only measure one centimeter.

Soldiers are twice the size of workers

Based on Hogue’s Latin American Insects and subsequent web searches, I believe these are termites in the genus Neocapritermes, which he refers to in an illustration as crooked jaw termites. The name certainly fits. My first thoughts after seeing one of these soldiers was that it was deformed. read more

Chrysalis Surprise

Posted on July 14, 2011 by Troy Bartlett

10mm | July 4, 2011 | Tupaciguara, Minas Gerais, Brazil

I collected this little chrysalis while I was in the field the day before I took this photo. I didn’t think I’d be able to get a good photo at the time, and I was curious to see what might emerge. Strangely, looking at this with my own eye, it appears opaque with a silvery and gold surface. With the camera and flash, it appears as above, somewhat transparent and showing what looks like a wing inside. I figured it would only be a short time to see the butterfly that might emerge. Well, I was half right. read more

Velvet Ant

Velvet ants are challenging to photograph. They always seem to know when you’re after them. They are either running so fast you can’t keep them in the frame (much less focus) or they find cover to hide under. I always just shoot like crazy and hope for the best.

Bee Mimicking Assassin Bug

For me, those wings are what really give this assassin bug in the family Reduviidae the appearance of a bee.

Beetle with Red and Black Elytra

25mm body | July 2, 2011 | Monte Alegre, Minas Gerais, Brazil

I spotted two of these beetles, both on tree bark at the base of trees. I don’t have any of my references with me, so I can only speculate about the family. Tenebrionidae, perhaps?

Cockroaches

Posted on July 7, 2011 by Troy Bartlett

30mm | July 2, 2011 | Monte Alegre, Minas Gerais, Brazil

I saw quite a variety of cockroaches in my relatively short outing to Monte Alegre. The first one, above, was the largest and was not altogether unattractive. It blended in well with the leaf litter.

The second one was a bit smaller, and was spotted in some low foliage.

This last one was the smallest, but the most robust.

It was moving slowly about until it encountered something tasty (rodent dropping?).

Ants Tending Leafhoppers

Posted on July 6, 2011 by Troy Bartlett

July 2, 2011 | Monte Alegre, Minas Gerais, Brazil

These ants are tending to some treehopper nymphs. Most of the ants are busy collecting honeydew, but the one on the bottom has noticed me and is on alert. I accidentally bumped the branch after this shot and all of the ants started running around looking for something to attack. I held up a leaf for a background here so that the ants would stand out.

In this next shot, I’m assuming the white areas are either treehopper eggs or a protective covering for the eggs. One of the adult treehoppers is also visible here, a darker shade of red than the nymphs. read more

Crypsis Challenge #11 Reveal: Moth

Posted on July 6, 2011 by Troy Bartlett

Did you find the moth in the image above? If not, don’t feel bad. I might not have seen it either, except I originally spotted the moth in a more conspicuous location. After a few shots (below), I deliberately spooked it in hopes that it would land in a location suitable for a crypsis challenge. Here’s an outline if you still need a little help finding it.

Moth revealed

Here’s where I originally spotted it. Not blending in so well, is it?

Camouflage fail

This moth’s shape suggests it might be in the family Tortricidae. It’s small, only about 15mm measured lengthwise in the photo below. read more
