Strawberry Root Weevil (pupa or newly emerged adult)
Scientific Name: Otiorhynchus ovatus
Order & Family: Coleoptera; Curculionidae
Size: Approximately 5 to 6 mm (0.2 to 0.25 inches) long as adults.
Natural Habitat
Typically found in soil near host plants (strawberries, small fruits, mint), in leaf litter, or crawling into homes through cracks and windows during summer.
Diet & Feeding
Larvae feed on the roots of strawberry, raspberry, and mint plants. Adults feed on the edges of foliage, causing characteristic notching.
Behavior Patterns
They are flightless and strictly nocturnal feeders. They often seek shelter indoors during hot, dry weather to avoid desiccation. They reproduce via parthenogenesis (no males required).
Risks & Benefits
They are agricultural pests that can damage berry crops, particularly larvae destroying roots. To homeowners, they are a 'nuisance pest'—harmless to people, pets, and structures, but annoying when invading homes in large numbers.
