Black vine weevil (Otiorhynchus sulcatus)
Clay-colored weevil (Otiorhynchus singularis)
Strawberry root weevil (Otiorhynchus ovatus)
Pest description and damage Adult weevils are small dark nocturnal beetles with a snout (rostrum) and elbowed antennae. Most of the species are all females and capable of laying eggs after a period of feeding to mature their ovaries. Larvae, found around roots of yew, are C-shaped, legless, and white with tan heads, up to 0.5 inch in size. Check base of unthrifty shrubs for girdling by larvae. This is especially important in new plantings. The larvae of all species are quite similar in appearance and habit: feeding on root hairs, larger roots and root crown. Look for notches in needles. Dead tips scattered in plants where weevils have girdled the twigs are common.
