Habitat:

Larvae live underground among plant roots, and adults prefer dark quiet spaces (Warner and Negley 1976).

Trophic Strategy:

Larvae feed on roots, and adults feed nocturnally on the foliage of a wider range of host plants (Warner and Negley 1976). North American host plants include maple, maidenhair, bittersweet, clematis, dracaena, hawthorn, cyclamen, strawberry, juniper, privet, mint, four o'clock, tuberose, rhododendron, rose, raspberry, nightshade, potato, spirea, yew, arborvitae, blueberry, and the European host plants include grape (Warner and Negley 1976).

Cyclicity:

Usually overwinter as larvae, but adults may hibernate in warmer climates (Warner and Negley 1976).

Life Cycle:

In the early summer, adults emerge from the soil, then must feed for approximately 4 weeks before they begin ovipositing (Oregon State University Extension). They oviposit their eggs in soil near plant roots and foliage, and oviposition ends by early September (Oregon State University Extension). Each adult may deposit more than 800 eggs in its lifetime, and its life expectancy can be 2 or more years (Alford et al. 1996). Larvae overwinter in the soil among plant roots, continue to develop in the spring when the soil warms up, then pupate in the late spring (Oregon State University Extension). Dispersal of this flightless weevil is dependent on the distances it walks and on shipments of horticultural products (Entomol. Soc. of Wash. 1999). It inhabits greenhouses, nurseries, vineyards, and other agricultural crops (Entomol. Soc. of Wash. 1999).
