Lasioderma serricorne

Lasioderma serricorne, more commonly referred to as the cigarette beetle, cigar beetle, or tobacco beetle, is a small beetle that shares a resemblance with the drugstore beetle and the common furniture beetle . The cigarette beetle, along with the drugstore and furniture beetles, all belong to the beetle family Ptinidae. The cigarette beetle can be distinguished from A. punctatum by its flatter thorax, whereas A. punctatum boasts a humped thorax. The cigarette beetle can be further differentiated from S. paniceum by its uniformly serrated antennae with unmodified apex, unlike the three-segmented apical "club" of S. paniceum. Additionally, L. serricorne has no evident grooves in its elytra, or hardened wing covers, compared to A. punctatum and S. paniceum which both have grooves.
