Flashy Coreid
January 31, 2010 | Tupaciguara, Minas Gerais, Brazil
Despite their common name of leaf-footed bugs, not all coreids have flattened hind tibiae. Â This flashy specimen instead has rather impressive hind femurs.

Another Bizarre Treehopper
January 31, 2010 | Tupaciguara, Minas Gerais, Brazil
I’ve shown a couple of odd treehoppers already, but here’s yet another variation on that theme. This time, I do kinda see a resemblance to an ant.
Dorsal view
Marshall’s 500 Insects includes a very similar looking treehopper identified as a Cyphonia species.

Lacewing under Leaf
January 31, 2010 | Tupaciguara, Minas Gerais, Brazil
Most lacewings are nondescript. So when I spotted this one on the underside of a leaf, I couldn’t pass it up. The markings are not unlike some Leucochrysa species here in the US.

Blister Beetles Defoliating
January 31, 2010 | Tupaciguara, Minas Gerais, Brazil
This plant was being devoured by dozens of these attractive blister beetles. Above I’ve caught one with a leaf fragment in its mouth. Below, you can see how they’ve stripped a branch clean. The frass seems to be exiting just about as fast as the plant goes in (must be a good source of fiber).
Beetles Defoliating
As these pictures show, the plant was literally crawling with these beetles.
Working on another branch
The dark backgrounds here are an effect of the camera flash. This was actually happening in broad daylight. How are they able to risk doing that? Blister beetles are so named because they defend themselves with a caustic compound, cantharidin, found in their blood. Predators soon learn to avoid them.

Dinner at the Cow Patty
January 31, 2010 | Tupaciguara, Minas Gerais, Brazil
Remember I said in the location profile for Tupaciguara that cattle are abundant? I was driving through one of the many cattle pastures at night when I noticed that some of the fresher cow patties were being visited by moths.
I suppose this shouldn’t be too surprising. I’ve seen plenty of butterflies taking nourishment from bird droppings and other animal scat. Well, at least something is benefiting from those cattle.
Some other random thoughts:
I wondered if anyone has ever done a study on how many and what types of species come to cow patties? That might be worthy of an Ig Noble prize.

Unidentified Nymph
January 31, 2010 | Tupaciguara, Minas Gerais, Brazil
Remember the recent crypsis challenge where Ted C. MacRae thought he also saw a noctuid moth in addition to the more obvious praying mantis? Well, that wasn’t a moth at all, but what sure looks like the nymph of some sort of homopteran.
I actually saw quite a few of these in the area. Here’s another one.
Another individual
I’ve been puzzling over this for quite awhile now. While I’ve encountered and seen pictures of plenty of homopteran nymphs with waxy appendages extending from their abdomen, I’ve never seen one with anything like the plumose structure shown here.

Planthopper
January 31, 2010 | Tupaciguara, Minas Gerais, Brazil
Based on the snout and the wing venation, I’m gonna say this one is a dictyopharid planthopper.

Attractive Caterpillar
January 28, 2010 | Caraça Natural Park, Minas Gerais, Brazil
This caterpillar seems fairly distinctive, but I haven’t been able to find anything similar. The white bands are odd. I can’t decide if they are normal or evidence of an injury.

Freshly Molted Treehopper Nymphs
January 28, 2010 | Caraça Natural Park, Minas Gerais, Brazil
There are a couple of freshly molted treehopper nymphs shown here. Just below them, you can see a shed exoskeleton. Their colors will return as their new skins harden. In the meantime, they inflate themselves so that their new skins harden larger than their previous ones.
Below is an adult that was hanging around a bit farther down the stem. That’s what they’ll eventually look like. You can see how the horn gets bigger with each molt.

Gonyleptid Harvestman
January 28, 2010 | Caraça Natural Park, Minas Gerais, Brazil
This image of a harvestman in the family Gonyleptidae is one of my favorites from my trip to Caraça Natural Park.
As a kid, I cherished my Golden Guide to Spiders and Their Kin. Ever since I saw an illustration therein of a wild looking Gonyleptid, I’ve wanted to find one. I got excited early in the trip when I found a shed skin. On the last night, I was out with my headlamp and I encountered not just one but two!
They were both difficult to photograph. Although slow moving, they just wouldn’t stand still. I had to keep herding them back onto the trail. Eventually, this one stopped in an area that made for a relatively uncluttered background.
