CARPET BEETLE DESCRIPTION

Adult Carpet Beetles are 1/16 to 1/8 of an inch long, round or oval in shape, and can be either plain black or covered with a mottling of yellow, white, and black scales. The larvae are approximately 1/4 of an inch long, rather stubby looking, and clothed with bands of stiff, erect, brown hairs. The body is wide in the middle but tapers at the end where you’ll find a thick tuft of hair.

ROVE BEETLE DESCRIPTION

Rove beetles are fast moving, long, narrow-bodied beetles, with short elytra and visible abdomens which are often hairy. They look somewhat like an earwig without the pincers.  They can be up to ¾” long and are normally found in the ground, under leaf litter and stones, as well as in ant nests.  These insects attack other insects such as aphids and ants, grubs, and root maggots in the soil.  Rove beetles are unusual in that their elytra are short and do not cover the entire abdomen.  Because of this, they are able to fold their long wings intricately under these short elytra but surprisingly can fly quite well.
