Bioluminescent Click Beetle

dsc_0282These click beetles have two luminescent spots located on the body behind their eyes. Unlike lightning bugs, these beetles do not flash, but remain constantly glowing.  The light intensity increases as potential predators draw near.dsc_0276dsc_0254I first discovered these beetles upon leaving work after a late evening in lab.  I noticed pairs of dots glowing at me from the mangrove trees and went in for a closer look.  I couldn’t quite make out the critter in the darkness, but after some quick online searches I realized that I had stumbled upon a group of bioluminescent click beetles!dsc_0257Available here :)
