Bess Beetle: Horned Passalus (Odontotaenius disjunctus)

This post was submitted to An Inordinate Fondness #2. Visit Birder's Lounge to learn more about beetles.

This Horned Passalus was making its way very slowly and gracefully over a fallen tree branch by the path just opposite the pool. The temperature was about 45 F which probably explains why it was moving so slowly. It had lost one antenna. When I picked it up to photograph the remaining antenna, it doggedly continued its steady pace across my hand. When I placed it back on the log, it simply moved on to the leaf litter as if nothing had happened.

I think I've also seen these common-named "patent-leather beetles."
