Like many other ornamental weevils the females of this species create a small egg chamber by folding over the margin of a leaf, then depositing several eggs in that chamber. It feeds on a wide variety of ornamental and agricultural plants, the adults feeding on the foliage and the larvae feeding on the roots. They are a particular pest on rhododendrons in the Pacific Northwest, as well as on strawberries and in nurseries and greenhouses.
Control with insecticides is aimed at killing the adult beetles, as the larvae are generally going to be in the soil. Contact insecticides applied to the foliage when adult beetles are present can be helpful.
