Striped Anole, Displaying

Posted on July 14, 2012 by Troy Bartlett

April 23, 2012 | Arikok National Park, Aruba

The Striped Anole, Anolis lineatus, was probably the species of lizard I most encountered in Aruba. I assume the common and scientific names refer to those dark broken lateral stripes, but it’s known locally as Waltaka.

Here’s another one, a female perhaps.

Female? Or a young male?

My earlier post of the lizard on a tree is also one.

After a good bit of googling, I came across a good free resource on the reptiles and amphibians of Aruba, link below.

Yellow/Black Treehoppers with Ants

Posted on July 14, 2012 by Troy Bartlett

~5mm | January 7, 2012 | Tupaciguara, Minas Gerais, Brazil

Here’s yet a different species of colorful treehopper. These too were found in association with ants.

A busy photo, but packed with natural history.

Roosting Bats in Aruba

Posted on July 10, 2012 by Troy Bartlett

April 23, 2012 | Arikok National Park, Aruba

While hiking around in Arikok National Park, I spotted from a distance some bats flying around below a small limestone overhang. I approached just close enough to snap a few pictures for possible identification.

I’m not nearly as close as this picture might suggest. I used my 100mm macro with a 1.6x teleconverter. This is also a significant crop from the original photo.

It appears I may have upset them, although I didn’t know that at the time. I’m surprised by their reaction. I didn’t figure my activity would disturb them. They weren’t in a cave, just beneath an overhang where there was plenty of indirect light. They were restlessly flying around even before I approached, perhaps trying to find a dark corner. read more

Ants Tending Treehoppers, Poorly Perhaps

Posted on July 9, 2012 by Troy Bartlett

~3mm | January 7, 2012 | Tupaciguara, Minas Gerais, Brazil

I had planned to post just a single photo of this scene with ants tending treehoppers. Here we see at least two different colorful treehopper instars, with one actively molting. Ants like the one shown above tended to this small grouping of treehoppers. As I was choosing a photo to post, I noticed something strange about the treehoppers though. Do you see it too?

Look closely and you’ll see that a few nymphs have parasites. I wasn’t sure at first, so I started looking through my other photos. Sure enough, almost every one had one or more parasites. The parasites seem to prefer hiding under the wing pads and below the thorax. read more

Aruban Lizard on Tree

Aruba could easily be called “Lizard Island”. You can’t take a step without seeing a few scurrying away. I don’t think there’s a square inch of sand that doesn’t have a lizard track in it.

Checkered-Fringe Prominent Rearing

Posted on July 4, 2012 by Troy Bartlett

30mm | 29 October 2011 | Suwanee, GA, USA

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.

Head on view

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.

20mm long | 11 May 2012

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. read more

Poison Ivy Caterpillar / Dimorphic Macalla Moth

Posted on May 20, 2012 by Troy Bartlett

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. read more

Tapinoma Ant Observations

Posted on May 2, 2012 by Troy Bartlett

April 13, 2012 | Twelvestones, Roswell, GA, USA

For several days I had noticed ants racing along the bricks at the base of one of my garage doors. I finally took a closer look to see what could be keeping them so busy for so long. They were streaming between a hole in my house and somewhere out in the front yard. I tried following, but these ants are tiny, only a few millimeters long. I quickly lost them in some pine straw.

Moving out

Turns out they were moving out of my house. The ones heading toward the yard were carrying eggs, larvae, and pupae. As I watched them though, I noticed something else leaving with them that didn’t look quite right. read more

Wild Goat

Posted on May 1, 2012 by Troy Bartlett

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.
