Dermestes ater

Dermestes ater is a species of beetle in the family Dermestidae, the skin beetles. It is known commonly as the black larder beetle or incinerator beetle (not to be confused with Dermestes haemorrhoidalis, the African larder beetle, also sometimes referred to as the black larder beetle). It is native to North America, but today it is found nearly worldwide. Like several other dermestid beetles, this species is a common pest of stored products.
