Emerged from old, rotting conk collected Mar. 19 from deciduous tree. Due to the length of antennomere projections, body shape, and depression on mesosternum (underside view), I'm calling this D. pallicornis. Oh yeah, the cornis are pallid too ;-)

This beetle is the first to emerge from the fungus sample, which I noticed contained small white grubs when I examined it in the field with my pocket loupe. My guess is that the grubs are the same species but I want to see if any other species emerge before linking the images to these.

This beetle will cross the Atlantic and be studied by Boris Büche in Berlin, comparing it to European members of the genus.

These beetles, like the related Puff*ball Beetles, are typically in tucked position, on their backs, or running around. Finally this one got thirsty enough from all the wall climbing and flight attempts that I got it to pause for a drink from a water droplet so I could capture some decent dorsal views.
