Bothrideridae

Bothrideridae is a family of beetles in the superfamily Coccinelloidea. They are known commonly as the cocoon-forming beetles or dry bark beetles. They occur worldwide with most native to the Old World tropics. In older literature, the family was often included in the family Colydiidae (e.g., ), but is now considered unrelated.

Description
These beetles are 1.4 to 12 millimeters long as adults. They generally have very elongated bodies, some over 4 times longer than wide. They may be cylindrical or somewhat flattened. They are yellow to black in color, some with various patterning and some with red spots. They are hairless to slightly hairy or scaly in texture. The antennae have 9 to 11 segments and are usually club-shaped at the tips. Larvae are up to 18 millimeters long and are elongate in shape.

Biology and ecology
Most beetles in this family live under tree bark. The larvae are ectoparasitoids of other insects, including other woodboring beetles, wood wasps, and carpenter bees.
