Beetles

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.

SAW-TOOTHED GRAIN BEETLE DESCRIPTION

Small, slender, dark brown insects about 1/8” long. Six saw-like “teeth” are found on either side of their pronotum (segment behind the head). Larvae are yellow-white and about 1/8 inch long. They have three pairs of legs and a pair of false legs on the abdomen.

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.  

LARDER BEETLE DESCRIPTION

Larder beetles are ¼ to 3/8” long, elongated oval in shape, and dark brown to black in colour with distinct, clubbed antennae. The upper 1/3 of the wing covers are covered with a wide, yellow band with six to eight dark spots on it. The underside of the body is covered with fine yellow hairs. The larvae are 3/8 to 5/8” long, brown and very hairy. They have two backward, curved, sharp spines next to the last abdominal segment.

ELMBARK BEETLE DESCRIPTION

Adults are brownish-black in colour. They measure approximately 1/8″ (2–3.5 mm.), with the long body covered with short, stiff, yellow hairs. The wings are deeply pitted. These pests are especially bad as they can transmit Dutch Elm Disease.
