The wing coverings, or elytra are fused together, so the adults can't fly. They are nocturnal and spend the days under leaf litter and detritus, until they begin to roam after dark. There are only females in the population!
Black vine weevils have been recorded on over a 100 host plants, commonly on azaleas, rhododendrons, yew, hemlock, cranberries....in other words a real bugger in nurseries, seed orchards and farms. The damage from the adults is mostly cosmetic consisting of nibbles on the greenery and it is the larvae that cause the real damage by eating the roots. They can cause considerable damage before they are discovered.
