This firefly, a beetle in family Lampyridae, probably in the genus Photinus, was on a weed in the back of our garden this evening. According to BugGuide.net there are 34 described species in this genus and identification of a single specimen by morphology alone is often impossible. So, I’m not even going to try. It’s a firefly and that’s good enough. One interesting fact about fireflies is that females in the genus Photuris are known to lure in males of Photinus species and eat them in order to obtain a defensive, steroid-like compound that they contain.
