Common NameRough Strawberry Root Weevil
SeasonalityUsually overwinter as larvae, but adults may hibernate in warmer climates (Warner and Negley 1976).
IdentificationLarvae are legless, creamy white, curved, and have brown heads (Gov. of Canada). The adult is reddish to brownish black, 6 – 8 mm long, and has hairy elytra (Warner and Negley 1976). The apex of its tibia is rounded (Warner and Negley 1976), it is smaller than O. sulcatus, but larger than O. ovatus, and its femora are not toothed, differentiating it from O. sulcatus and O. ovatu (O'Donnell 1984). The adult's elytra are fused, the weevil is flightless, and has elbowed antennae. Its rostrum is medium in length, shorter than that of O. sulcatus, but longer than that of O. ovatus (Warner and Negley 1976).
