Beetles have chewing mouthparts and eat both plants and other insects.
Beetles undergo a complete metamorphosis - from egg to larvae to pupa to adult. There are some 17,000 species in North America alone. Feeding habits vary widely, although most beetles consume plant material. Most adults have a long, thin snout with chewing mouthparts at the end. There are 3,000 or so species in this group in North America.
