These beetles, like the other members of the Anobiidae family, can easily be mistaken for spiders – hence the name. But they definitely have six legs, not eight. The shiny elytra are orange-brown, and the head, thorax and legs are covered in dense, short hair. They have droplet-shaped bodies 2.5 to 3.5 mm long, and long antennae.
The somewhat crescent-shaped larvae are yellowish and hairy. They measure up to 4.5 mm long.
These tiny brown oval beetles are 2.2 to 3.5 mm long. They have longitudinal rows of fine hairs on the elytra (wing covers).
They are easily confused with cigarette beetles (Lasioderma serricorne), but their antennae help to tell them apart: the drugstore beetle’s antennae end in a three-segmented club, while those of the cigarette beetle are serrated.
The whitish, crescent-shaped larvae are covered with long hairs and have brown heads. They are up to 4 mm long.
These large, oval beetles are 1.7 to 3 cm long. Their colour varies from yellowish orange to reddish brown. Their short antennae end in clubs made of plates called lamellae, which unfurl into a fan.
Their elytra (wing covers) have three black dots on the side and a fine black line on the dorsal portion. Southern specimens have light brown legs, while northern ones have darker legs.
The fleshy grubs are whitish and C-shaped, and may be up to 5 cm long.
These elongated beetles are 8 to 13 mm long. They are tan or greenish, with long orange-brown legs. The wings do not completely cover the abdomen.
The whitish grubs have brown heads. In the soil they adopt a crescent-shaped position. In the final larval stage, they have three pair of long legs and are up to 13 mm long.
These beetles are recognizable by their black colour and the small white spot formed by the scutellum (the triangle at the base of the elytra). They have strong, long, reddish legs. The females are larger than the males, and their elytra (wing covers) often have small white spots. Their antennae are barely longer than their bodies, whereas the males’ antennae are twice as long as their bodies. Without their antennae, the insects vary in length from 13 to 27 mm.
The legless larvae are whitish and slightly flattened, with brown heads. They can grow to more than 4 cm long.
These reddish-orange beetles with their black spots are easily recognizable on their host plants, milkweed. Their legs and long antennae, typical of the long-horned beetle family, are black. The species owes its Latin name to its four eyes (tetra = four), which are actually two eyes split in two by the antennae. The adults are from 8 to 15 mm long.
These tiger beetles are easy to recognize with their iridescent green or blue-green colouring and white-spotted elytra (wing covers). As their name indicates, they usually have six spots, but some specimens have only five, or even two or none at all. They have large eyes and powerful sickle-like mandibles. Their bodies are 10 to 14 mm long.
The brownish larvae have dark heads with large mandibles.
These oval-shaped insects are slate grey to black, 7.5 to 11 mm long, with elbowed antennae. Their elytra (wing covers) are covered with tiny concave areas and patches of short grey or yellow hairs and golden “scales.” They are flightless, since the elytra are fused, but can run quickly.
The legless larvae are creamy white with light brown heads.
These beetles are recognizable by their bright metallic colours. The head and thorax are usually green, and the elytra (wing covers) are copper. There are five small tufts of white hair on either side of the abdomen. They reach 12 mm long.
The white grubs have brown heads and three sets of legs. They adopt a crescent-shaped position in the soil, and may be up to 32 mm long.
