RECOGNITION
Recognition
One of the most diverse animal families. Usually dark, a few colored and/or patterned, sometimes with red. Body shape variable--elongated to more oval, usually flattened. Many large species are flightless and have fused elytra. First abdominal sternite entire, not divided by hind coxae (unlike Carabidae). Eyes usually notched. Antennae variable [thread-like (filiform), bead-like (moniliform), or clubbed], typically 11-segmented, with insertion concealed from above. Tarsal formula 5-5-4.

Diversity
One of the largest insect families, with ca. 1200 spp. in ~190 genera in America north of Mexico (and almost 20,000 spp. worldwide); ca. 225 spp. east of the Mississippi River and almost 5 times as many in the West.

BIOLOGY
Many species have chemical defenses.
Food
Many are scavengers of plant material as both adults and larvae. Some attracted to carrion, dead insects, dung. Some feed on fungus, often found under bark. Some are pests of stored grain and of insect collections.
Habitat
Typically found under stones, decaying logs, bark, on bracket fungi, or on the ground. A few species diurnal, found in open. Many species are adapted to desert conditions.
Range
Worldwide and throughout NA, much more diverse in the western states.
