|A nest of recently hatched spiderlings disperesed from a small, stream-side plant in Rio Camarone, Sirena.|
While sampling Rio Camarone near the Sirena field station, I wandered upstream and noticed an orb weaver’s web. As I moved passed it, I bumped a leaf with a perched fly and the fly flew right into the spider’s web. Thus, it’s psuedo-unnatural, but from the look of the third picture, similar prey items are usually encountered by this spider species anyway. I had seen a number of flies from this family perched on leaves adjacent to streams many times in the past, and I hope one that I’ve collected for Dr. Foote will provide an identification.
Helena Molina, a professor at the Biology Department at University of Costa Rica, is carried across a small stream on the Osa as we hiked to Rio Claro to sample Characids. A recommendation to future biologists: Think twice about doing graduate work with Helena… unless you’re looking for a workout too.
