Origin:
Possibly a native of Europe, but now found throughout the world.
Biology:
The species name of “stercorea” refers to the Latin name for excrement or dung, a reference to the presence of this beetle in moldy, decaying materials. It is an occasional stored food pest, but would normally infest food products in very poor condition, particularly those in damp condition with fungus growing on them. Adults run quickly and are able to fly.
Identification:
The adult beetle is a nondescript insect less than 3 mm long. It is somewhat flattened top to bottom, oval in shape, and reddish brown in color. The antennae are long and thin and have a 3-segmented club at the end. Under magnification a fine layer of short hairs will be found over the elytra and thorax.
Characteristicts Important to Control:
If these are found within a structure it is necessary to perform a careful inspection to find the source. Disposing of infested food products will generally control the problem. If the beetle is found in damp places controlling the moisture source and drying out the area are needed.
