Hunting Spider on Grass

Posted on April 14, 2012 by Troy Bartlett

This attractively marked hunting spider spider was resting on a blade of grass after a rain. I’m being intentionally vague by saying hunting spider here, because I really don’t know how to narrow it down to even a family.

With those racing stripes, one wonders how quickly it moves.

Parasitoid Wasp Emerging

Posted on December 7, 2011 by Troy Bartlett

Each one of these eggs from the underside of a leaf was parasitized by a wasp.  Their barrel shape with round fringed caps suggests they might be stink bug eggs. Had a stink bug nymph emerged, the caps would have been neatly opened. Instead, they each have a roundish hole chewed in them. In fact, there’s a parasitoid wasp straggler chewing its way free from the rightmost egg.

I might be seeing things, but you can almost make out the wasp’s body through the transparent egg shell.

I didn’t notice at the time, but a mite came along. read more

Bronze-backed Climbing Skink

I thought it would be difficult to identify this skink, but it turns out there are only three skinks in Costa Rica. Only two of those occur in the area I was in. And only one, Mabuya unimarginata, is bronzed like this one.

Chiefly arboreal, this one was nonetheless basking on a log near the ground.
