Two-Banded Japanese Weevil

Michael C. Thomas, FLA Dept.of Agriculture & Consumer Services, Bugwood.org
Some of the plants attacked by the twobanded Japanese weevil are ash, azalea, barberry, burr marigold, camellia, dogwood, lilac, mountain laurel, privet, rhododendron, rose, spirea, strawberry, and weigela. Twobanded Japanese weevil larvae feed on plant roots, but the adults do more serious and apparent damage. The weevils feed extensively on new leaves, shoots, and inner foliage. As a result, infested plants are tattered and unhealthy in appearance.

The twobanded Japanese weevil is parthenogenetic (no males have been found). Eggs are deposited in folds along the margins of leaf fragments or in dead leaves that have the free edge sealed to form a pod. After hatching, the larvae burrow into the ground and feed on roots. These weevils have fused wing covers and no flight wings and thus are unable to fly. They feed during the day, but if disturbed, drop to the ground readily and remain motionless. There is only one generation each year.
