Glasswing Butterfly

Glasswing butterflies lack scales on parts of their wings, leaving those parts transparent.

Though similar looking, this is not the species (Greta oto) commonly found in many of the butterfly houses I’ve visited. That one’s range doesn’t extend into South America. This is probably a closely related species. I was surprised there are so many that look very much alike. Check out this Florida Museum of Natural History page on the tribe Godyridini to get an idea.

Target Tortoise Beetle

I’ve seen variations on this pattern for tortoise beetles throughout Central and South America. I often see the species referred to as target tortoise beetles, though a quick google search seems to confirm my suspicion that that common name applies to many different species across several genera.

Ants Herding Treehoppers

These ants have quite effectively corralled their herd of honeydew producing treehoppers.

There’s a lot to see here if you look carefully. First, it looks like quite a few of the life stages of the treehoppers are present. There’s the dark adult in the center, an early instar in the bottom center, and the majority appear to be middle instars.

In the detail below, you can see the ant on the right has just taken a drop of honeydew and the dark adult has a drop waiting.

Fly with a Humpback

I just couldn’t pass up this interesting looking fly. Flies are a difficult order, and I quickly gave up on narrowing down any sort of id.

Caraça Tiger Beetles

I encountered a handful of these tiger beetles. At least, I think that’s what these are. I hope I don’t embarrass myself.

Most of them were up in trees and bushes as suggested by the first photo. I only encountered one on the ground.

From a distance, I mistook the first one for a large ant. Indeed, they move more like an ant than what I expect from a tiger beetle. I believe they may in fact be mimicking ants, and I found some references to back that up. None gave even a general identification though, so I wasn’t able to search for any online photos. read more

Ant tending Caterpillar

Here’s an ant in the Formica genus tending a caterpillar in the Lycaenidae family. The ant has just taken a drop of a sugary substance produced by a gland at the rear of the caterpillar. Here’s a shot from about 10 seconds earlier where you can see the drop sitting atop the gland and the ant fast approaching.

Sugary drop produced for tending ants

I’m not sure what flowers these caterpillars are eating, but they are pretty well camouflaged settled in among the flower buds. Once I spotted the first one, I started looking for them and found quite a few wherever I spotted these flowers. read more

Treehopper

I actually saw quite a few of these in various places throughout the park. I’m sure that headdress serves some useful function. I’m just not quite sure what.

In this excellent little book there’s a very similar looking treehopper identified as a Bocydium. I assume the one shown above belongs to that same genus.

Paper Wasps and Parasitoids

When I spotted these paper wasps alongside the trail, I only halfheartedly took a few shots. Mostly, I just didn’t think I’d be able to get an attractive photo out of it. So when I was reviewing my shots, I just about deleted all of them, including this one.

At the last second though, I noticed something unusual in the photo. I call these sorts of discoveries where I notice something in the photo that I didn’t realize was there when I took it “easter eggs.” It happens often enough that I just decided to add a new category for that here on my blog. read more

Handsome Mosquito

Who knew a mosquito could be so attractive? Looks like a male based on those plumose antennae.
