Here is one of the interesting visitors I had to my black lights at Hawn State Park this summer. Bolitotherus cornutus, or horned fungus beetle is in the darkling beetle family, Tenebrionidae. I wish I knew of their preference for polypore fungi as larvae and adults so that I could have photographed them on more suitable substrate.
