Bullet Ant

This species, Paraponera clavata, is the infamous bullet ant. In Costa Rica, its common name is “bala,” which also means bullet. If somehow you don’t already know, the name derives from its powerful sting. Getting stung is said to be as painful as getting shot. I’ve also heard it referred to as “hormiga veinticuatro”, or  24 hour ant, for the duration of the pain. I’m happy to say I can’t testify to any of this personally.

I saw plenty of these large ants. It was difficult to get any images though, as they seem to be constantly on the move. These images were taken at night as the ant crawled around on a tree trunk. read more

Headlight Beetle

This click beetle in the family Elateridae was another night find. I’d like to say those light producing organs on the prothorax drew my attention. In reality, its “headlights” were “off” when I found it.

There are many species with these light producing organs spread across many genera, but they are all commonly referred to as headlight beetles.

On a side note, my blacklight flashlight was kind of a bust otherwise I’m afraid to report. I had hoped to find some scorpions at least, but this beetle was the only thing it turned up. read more

While I work on some longer posts, here’s another attractive unidentified beetle to ponder. Maybe a pleasing fungus beetle in the family Erotylidae?

I won’t venture an identification here, but it was too attractive to pass up! Can anyone narrow it down for me?

Micropezid, ovipositing

While recently reviewing my shots of this fly in the family Micropezidae, I was surprised to find that I unknowingly got a shot of her laying an egg. Here’s another shot for comparison, where she has concealed her ovipositor beneath her abdomen.

Here’s a crop from the first photo, showing the ovipositor and the egg.

Ovipositor and egg

Everything I’ve read indicates that most larvae develop in decomposing matter, so it seems strange she would be placing an egg on a leaf surface. Perhaps this is  just a method of random distribution, and the egg just falls where it may on the ground below. read more

Here’s another one of those planthoppers from the family Nogodinidae, pretty much just like the earlier one I posted.

True Bug Eggs

I found this row of eggs on the underside of a small log that was laying on the ground. They look like they belong to a true bug (order Hemiptera) of some sort. Here’s a closer look.

Here’s a somewhat unusual leafhopper. I don’t recall ever seeing one with an upturned snout.

Mantidfly

I was thrilled to find this mantidfly (family Mantispidae) on the underside of a large leaf. I’ve seen plenty of these attracted to lights at night, but I rarely encounter one in a natural setting.

Black and Yellow Leafhopper

In an earlier post I remarked how I initially mistook a colorful micromoth for a leafhopper, and that I later saw a similarly marked leafhopper. This is the leafhopper I had in mind, although now I can’t really say they look all that alike.

I did see quite a few of this variety of leafhopper though.
