Stegobium paniceum (Linnaeus, 1758) - (drugstore beetle)
The beetle is common in houses and food stores, infesting various organic products.
Synonyms:
Sitodrepa panicea
General Features
Stegobium paniceum is a polyphagous insect which is called drugstore beetle or bread beetle. In warmer regions of the northern hemisphere, these beetles are active between the months of April and September. During this time they enter houses, warehouses, museums and apiaries in search of suitable food. They feed on both animal and plant materials. Starchy products (amylophagous) are the food of choice of bread beetles, however they can occasionally infest wood. Larvae and adults stay away from light. But they are attracted by ultra-violet light and can be trapped by this method.

Identification Criteria
Adults of Stegobium paniceum are 2 to 3.7 mm long. Their body is cylindrical, oblong and covered with very fine flat bristles. Their thorax is wider on the sides and is sharply domed, grainy in appearance and has a thick pubescent surface. Elytra have lengthwise rows of pits (striations). The head is partly covered by the hood-like pronotum. The antennae have eleven segments with the last three forming an elongate club. In the very similar cigarette beetle (Lasioderma serricorne) the antenna is serrated and club-less. S. paniceum has a yellowish brown to deep dark brown coloured body and legs. Larvae are 4-5 mm in length during their last instar. The larval body is arched and white in colour.
