Cimex adjunctus (Eastern Bat Bug)
Description: It resembles the common bed bug in size and appearance but has longer hair on its thorax.
Habitat: Found in the Eastern parts of North America, often in bat roosting areas like attics, wall voids, and chimneys.
Hosts: Prefers bats but may feed on humans if bats are unavailable.
Cimex pilosellus (Western Bat Bug)
Description: Similar in appearance to the Eastern Bat Bug and the common bed bug. The longer hairs on its thorax are the distinguishing feature.
Habitat: Found in Western North America, especially in areas where bats roost.
Hosts: Bats are their primary host, but they can switch to humans without bats.
Cimex japonicus
Description: This species of bat bug resembles other Cimex species, with flat, oval bodies and a reddish-brown hue. Their subtle morphological differences often require expert attention or a microscope for differentiation.
Habitat: As the name suggests, Cimex japonicus is native to Japan. It is primarily associated with bat roosting sites, such as caves, old buildings, attics, and other secluded areas.
Hosts: Cimex japonicus feeds primarily on bats. However, if the bat population dwindles or if bats vacate their roost, these bugs can resort to feeding on humans, causing skin irritation similar to bed bug bites.
Cimex latipennis
Description: Much like its relatives, Cimex latipennis has a flat, oval body with a reddish-brown color. It also has tiny hair-like structures, but identification often requires more than just visual examination due to its resemblance to other Cimex species.
Habitat: This bat bug is native to the Pacific regions of North America, especially in areas where bats roost. It can be found in secluded areas, old buildings, attics, and caves.
Hosts: Bats are the primary hosts for Cimex latipennis. However, in the absence of bats, these bugs can shift to feeding on humans, causing similar bite symptoms as bed bugs.
