While running to meeting on the University of Florida campus, I looked down and spied this creature on the edge of a concrete walkway. While about the size of one of our local palmetto bugs (a deceivingly quaint name Floridians have bestowed upon one of the local cockroach species), this large docile beetle was far less menacing. I was entranced by its eye spots, and by the discovery of yet another new species (I am a transplant down here and very much dig the constant appearance of novel little beasties).
Due to its unique appearance, it was easy to later discover this insect’s identity – the speckled eastern eyed click beetle, Alaus oculatus. Among its other common names is the eyed elater. Their larval form is known as a wire worm, and due to its carnivorous diet, is often valued by gardeners for its ability to rid vegetation of other less desirable residents.
Click beetles are members of the family Elateridae and produce their trademark sound when their spine snaps into a groove located on their mesosternum (basically like a bug chest plate). They do this when righting themselves if flipped over, and this snapping action may allow many members of this family to propel themselves away from harm quickly. Additionally, the presence of eyespots in insects are often suggested to be a form of predator deterrence.
