Attagebus unicolor (Brahm)
Identification: Adults are about 1/8-1/4” long. Color is dark brown to black. Males are up to 2 times larger than female
Lifecycle: Females usually lay around 90 eggs. Eggs are laid in lint in areas that have accumulated under baseboards, in cracks, and crevices, etc. Eggs hatch in 5 – 16 days depending on conditions. Egg to adult is usually 177 – 370 days, but can take nearly 2 years.
Behavior: Will feed on both animal and plant materials. Feeding on hair, fur, feathers, dead insects, and plant foods such as cereal, nuts, seeds, cayenne pepper and flour.
Larvae feed on fabrics capable of making small or large irregular holes. On furs, they leave the hide undamaged, cutting the hair at the base.
Adults are found outside and active when the weather is warm. They can be found on flowers feeding on the pollen. Can also be found in the nests of birds, rodents, and insects. In the spring they can be found around windows indoors. Breeding areas include wall/ceiling voids where cluster flies, yellow jackets, or honeybees have lived. They tend to breed where lint, dead insect parts, and pet hairs have accumulated feeding on dead insects.
