Weevil

Natural Habitat

Highly varied depending on species; can be found in fields, forests, gardens, stored food products, and homes.

Diet & Feeding

Mostly herbivorous, feeding on various plant parts including leaves, stems, roots, seeds, and fruits. Some species are serious agricultural pests.

Behavior Patterns

Many weevil species are known for playing dead or dropping from plants when disturbed. They have a characteristic elongated snout (rostrum) with chewing mouthparts at the end. Their life cycle typically involves egg, larva, pupa, and adult stages, with larvae often feeding inside plant tissues.

Risks & Benefits

Risks include being significant agricultural and stored product pests, causing damage to crops (e.g., cotton, maize, wheat) and stored grains. Some species can infest homes, seeking shelter. Benefits can include acting as biological control agents against invasive weeds (e.g., some thistle weevils).
