Cartodere constricta
Plaster Beetle
Cartodere constricta, commonly known as the plaster beetle, is a minute lathridiid beetle measuring 1.3–2.0 mm in length. Native to the Palearctic region, it has become established in the Nearctic through human-mediated dispersal. The species is a mold feeder associated with stored products, buildings, and organic debris in dry environments. It serves as a documented phoretic host for the mite Tarsonemus ascitus, which attaches specifically to the lateral and underside surfaces of the beetle's prothorax.
