Odontotaenius disjunctus (Horned Passalus)
According to Bugguide.net, the common name for this beetle listed by the Entomological Society of America is horned Passalus. The common name used by laypeople, however, is Bess Bug. This apparently comes from the French word, baiser, “to kiss.” That in turn probably refers to the sound it makes (stridulation), which sounds a bit like a squeaky “kissy” sound. They eat rotting wood, so it was no surprise this was found where it was, in an area that has a fair amount of wood for beetles to eat. This one is dead, as perhaps you can tell, which made it much easier to photograph, although because of that it lacks a certain something. Still, I think it’s a beautiful beetle. It looks to me like a quilter went over the elytra (the hardened forewings on its abdomen) an put neat rows of stitches down their length.
