foliage of strawberry and various Rubus hosts. They also damage the blossoms and other vegetative tissue. On strawberry, eggs are deposited in holes made in the petioles, in the stalks of the blossom trusses and in the tips of the stolons, often in small groups of up to four (cf. strawberry blossom weevil, Anthonomus rubi, p. 154). Tissue beyond an oviposition point, within which the larvae feed, withers and dies. Larvae feed for a few weeks and, when fully grown, pupate in the soil. The adult stage is reached a few weeks later. Individuals, however, remain in situ, and do not emerge until the following spring. Adults are 23 mm long and black with a greenish-blue sheen; they are readily distinguished from those of A. rubi (p. 154) by the antennae, which lack a scape.
