This beetle is found in decaying fungi, under dead bark containing fungi, in shelf fungi and in moldy vegetable material. This one was photographed along Missouri Trail.

These mold-feeding beetles are sometimes found in decaying plant material, damp cereals, grains, herbs, spices, cheese, jam, fibers and carpeting, especially in cellars. Attracted by lights, these small beetles, can crawl or fly through window or door screens, and then wander aimlessly.
