• Cimex pilosellus

  Western Bat Bug, Bat Bug

  Cimex pilosellus, commonly known as the western bat bug, is a blood-feeding ectoparasite in the family Cimicidae. The species is native to North America and primarily parasitizes bats, though it can bite humans when bat hosts are absent. It is morphologically similar to the common bed bug (Cimex lectularius) and requires microscopic examination for accurate identification. The species has been documented across western North American regions.
