Diving Beetle - Acilius

Diving Beetle - Acilius
Fort Bragg, Cumberland County, North Carolina, USA
February 19, 2004
Size: over .5 inches
When the neighbors got a trampoline we found these on it. They've since moved. I never saw one of these before the trampoline, and I haven't seen one since. Also, we don't have water near us.

Moved
Moved from Predacious Diving Beetles.

Male dytiscid
This is a nice shot in that it clearly shows the dilated (expanded) front tarsi ("feet") that male dytiscids have, the better to grip the female during mating.

Trampoline
You know I was just reading the Peterson Field Guide to Beetles (I'm such a nerd!) and I see where it specifically says that Predacious Diving Beetles are migratory and after a migratory flight they close their wings and plunge into whatever appears to be water (objects of low reflectivity). I guess that explains it.
