Plochionocerus sp. (Staphylinidae)
Jatun Sacha, Napo, Ecuador
Here’s a beetle that’s hard to miss. Over an inch long and brilliant metallic blue, Plochionocerus rove beetles roam the leaf litter of Neotropical forests looking for prey. This one rolled up into a defensive ball when I approached it with my camera (top), but after a couple minutes it unfurled and walked off (bottom).
