Colorado potato beetle (likely larva)
Leptinotarsa decemlineata
- Order & Family
- Coleoptera; Chrysomelidae (leaf beetles)
- Size
- Adults are about 9–11 mm long; mature larvae reach roughly 8–10 mm. The pictured individual appears to be a late-stage larva or pupa.
Natural Habitat
Vegetation and soil in gardens, farms, and disturbed areas, especially where potato-family plants grow.
Diet & Feeding
Larvae and adults primarily eat foliage of potato, tomato, eggplant, and other Solanaceae. Heavy infestations can completely defoliate plants.
Behavior Patterns
Adults overwinter in soil, emerge in spring, and females lay yellow egg clusters beneath leaves. Larvae pass through four stages, then drop into soil to pupate; multiple generations may occur annually.
Risks & Benefits
It is a significant agricultural pest and readily develops resistance to insecticides. It has little direct benefit to humans, though it is part of food webs as prey for birds and predatory insects.
