The adult beetles are black with white, brown, and dark yellow scales in an irregular pattern. These scales can wear off, and older adult beetles look solid black or dark brown. They are about a tenth of an inch long. Mature larvae are the same length but look very different. They have light and dark stripes with tufts of dark hair covering their bodies. They are wider towards the front of their bodies and taper towards the back.

Adult Varied Carpet Beetles lay around 40 eggs that take 10 to 20 days to hatch. The larval stage lasts anywhere from 220 to 630 days, and the adult stage is only about 2-5 weeks.


These are slightly larger than varied carpet beetles at about an eighth of an inch and have a highly variable scale pattern with white, dark yellow, orange, and black colored scales. The scales can wear off, and the beetles will appear dark black. The undersides of these beetles are white.

The larvae are white and mature larvae turn dark red or chestnut colored. They are opposite of the varied carpet beetles in that they are wider in the front, narrower in the back.

These beetles are nearly round and roughly the same size as the other varieties. They are gray to black with small white scales with a band of reddish-orange scales running down the back and around the eyes. The larvae are a red-brown color and are a quarter of an inch long, covered in dark brown hairs.
