Carpet Beetle, Anthrenus varbasci
The varied carpet beetle, Anthrenus varbasci, are about 0.7 centimeters (0.3 inches) long. The larvae
are a little longer. The larvae are the real distructive agents. They eat hair (wool) insect
carapace, and other protein containing particles. Their frass and the damage done to their food
source materials is evident by marks left by their grazing.
Anthrenus varbasci is one of the "Carpet Beetles" (Dermestidae).
Significance in the Environment:
Anthrenus varbasci larva will eat wool, silks, skins, furs, feathers, hair, horn, cereals, red pepper, fishmeal, etc, but
their favorite food is dead insects and spiders. According to Ebeling (see below) this beetle larva will even eat linen,
cotton, and synthetic fibers, except for rayon acetate. The adult beetle eats primarily pollen and nectar. They often
infest wasp nests. The adult beetle tends to enter homes in the spring and early summer.
