Lasioderma serricorne (Fabricius, 1792) - (cigarette beetle)

The beetle infests tobacco, oil seeds, dried fruits/nuts and various organic products in houses and stores. The damage is mainly done by the larvae. It has a world-wide distribution but is found outdoors mainly in warmer regions.

External Morphology and Identification Marks

The cigarette beetle is very small, about 2-3 mm long with a reddish brown colour. The body is rounded, oval shaped, and the head is usually hidden under the large pronotum. Cigarette beetles have fine hairs on the elytra. They are very similar to the drugstore beetles but can be distinguished by:

Vernacular names
• Deutsch: Tabakkäfer
Kleiner Tabakkäfer
Zigarettenkäfer
• English: cigarette beetle
tow bug
tobacco beetle
• Español: cascarudo del tabaco
cascarudo cigarrero
• Français: vrillette du tabac
lasioderme du tabac
• Português: bicho-do-fumo

Cigarette beetles have antennae with serrated margins, while drugstore beetles have antennae which have a 3 segmented club at the end.
The elytra surface of cigarette beetles is smooth while that of drugstore beetles has a striated texture.

Habit

Cigarette beetles often pull their legs to the body, tuck their head and lay motionless when disturbed. Cracks, nooks, and dark crevices are the common places where these beetles can be found. In bright open areas they are very active, flying readily to find a refuge. Most often cigarette beetles can be seen flying at dusk.
