These aquatic beetles are fun to watch as they spin around in circles on top of the water like little black bumper cars! They are not easy to photograph because they move so fast. There were 3 of these beetles, but I could only catch 2 of them in this photo. Whirligig beetles have split compound eyes, the upper part allows them to see above the water, the lower part allows them to see below the water at the same time. I could find only the genus name for this insect. According to my Audubon Insect Field Guide the only way to identify the species is to get up close and personal with the posterior end of the male! Since I'm not an entomologist (insect scientist) and I wouldn't have a clue how to examine the rear end of a hyperactive beetle, I'll just be happy with the genus name! :) These beetles eat small insects that fall into the water.
