Today’s cat is in the Pyralidae family. It is most likely Pococera expandens (double-humped pococera moth), but with at least 27 species in this genus and many of which that feed on oak, upon which this one was found, other species could be an option. This guy was photographed in early July during a WGNSS Nature Photography field trip at Prairie Garden Trust in Calloway County, MO.
