Stegobium paniceum (Linnaeus) - drugstore beetle
is common in houses and food stores, infesting various organic products.
Synonyms:
Sitodrepa panicea
General Features
Stegobium paniceum (Linnaeus, 1758) is a polyphagus insect which is often called a bread beetle. These beetles show activity 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. As they are attracted by ultra-violet light, they 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). Antennae have eleven segments with the last three forming an elongate club. Antennae have two rows of small spines on the ventral side of the first six segments. Their head is partly covered by a hood called a pronotum.
Stegobium paniceum have 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.
