Advertisement Being an entomologist means I have an endless list of insects that I want to find. Last summer after moving to Colorado I was able to cross one of those off my list (along with quite a few others). While I was collecting ants I looked over and saw my very first Gibbifer californicus. After a multi minute jig of joy and air fist pumping I eventually took this picture. This species is in the family Erotylidae (pleasing fungus beetles) and the larvae feed on wood-destroying fungi. They are found in the southwest U.S and Mexico and I found them to be relatively numerous in northern CO.
