Thread-legged Bug with Spider Prey

This thread-legged bug appears to be hanging in mid-air, but in fact it has delicately balanced itself on a spider web. Its beak holds a small spider that it must have just plucked from the center of the web.

Some thread-legged specialize in spiders, and I wonder if this might be one of them. Some are even known to lure the spider by plucking at the web like captured prey might.

A Couple of Dictyopharid Planthoppers

These dictyopharid planthoppers are a nice addition to my virtual collection.

It took many attempts before I got this shot where both planthoppers were in the plane of focus. That’s sometimes difficult enough with small subjects, but even more so when they are above your head. I convinced myself the Canon 60D’s flip-out view screen with live view would come in handy for situations like this. Shots like these that I’d otherwise have missed make me feel better about the expenditure. read more

Hunting Spider on Grass

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.

Clearwing Moth

This colorful moth in the family Arctiidae looks a little worse for wear. Nonetheless, it’s quite striking and I’m sure a fresh specimen must be even more so. I later saw another one of these near a porch light so it might be a common species.

While searching for a possible identification, I came across this blog posting. It describes how hundreds of caterpillars were invading people’s home in Piracicaba, São Paulo. With the help of a biologist, they found both the host plant and some pupae for rearing. What emerged looks very much like the moth above, identified as Cosmosoma teuthras, a common moth throughout Brazil. Check the site for photos of the caterpillars, pupae, and an adult. I have no idea if there are similar looking species, but it seems like a good possibility for what I found. read more
