Barypeithes pellucidus, is sometimes referred to as the juniper root weevil, hairy broad-nosed weevil, or hairy spider beetle. It was first found in Oregon in 1934. It has been found feeding on strawberry leaves and also girdling christmas tree replants. Additional hosts include aster, buttercups, cherry, dandelion, elm, filbert, hawthorne, hemlock, oak, ragwort, and thistle.
Feeding behavior is different than other root weevil adults. In strawberries the adults feed in the leaf buds. As the leaves unfurl interior holes are evident. There are often matching holes on either side of the midrib. Other differences, this root weevil species has both males and females; and adults of this species can be found feeding during the day in some situations.
Adults emerge as early as mid-April, earlier than other common root weevils such as the black vine root weevil, Otiorhynchus sulcatus.
