Elytra smooth, with very short hairs,but without striae. Antennae about half as long as body, 11 segment, 4-10 segment serrate.Larvae white and scarabaeiform.Stegobium paniceum (Linnaeus) – Drug Store BeetleSimilar to Lasioderma serricorne but last three segments of antennae form a large looselysegmented club. Elytra have longitudinal striae.FAMILY BOSTRICHIDAEBody cylindrical, head ventral to prothorax. Pronotum have rasp like teeth or hooks,antennae straight and have a loose 3 or 4 segmented club. Apically elytra flattened and slopeventrally more or less steeply (declivity). Tarsi 5 segmented.Rhyzopertha dominica (Fabricius) – Lesser Grain BorerAdult 2-3mm long typical Bostricid . Pronotum rounded at front with transverse rows ofteeth. Flattened tubercles centrally and posteriorly. Scutellum between Pronotum and elytra almostsquare. Elytra have regular row of punctures and short setae that curve posteriorly. Apically elytragently convex. Antennae 10 segment with a loose 3 segment club.Larvae white and parallel sided. Leg short, head capsule small.Prostephanus truncatus (Horn) – Larger Grain BorerTypical cylindrical bostrichid shape. Body 3-4.5mm long. Declivity flattened and steep,many small tubercles over surface. The limit of declivity Apically and laterally marked by carina.Antennae 10 segmented with a loose 3 segmented club. Stem of antennae slender and clothedwith long hairs and the apical club segment is as wide as, or wider than , preceding segments.Larvae white and parallel sided. Leg short, head capsule small.
