vegetable weevil |
Listroderes costirostris obliquus |
The vegetable weevil, feeds as a larva and an adult, primarily at night. The adult is a dull gray-brown beetle, about 3/8- inch long, with a pale gray mark near the posterior end of each wing cover, forming an inconspicuous V-shaped spot. The pale green legless larvae have brown heads. Larvae may feed on tobacco in plant beds during early spring. Larvae may damage or destroy the bud and eat holes into the leaves. Larvae appear in spots and may damage a good size area. Because they feed mostly at night, it is difficult to locate them. However, the feeding damage is usually easy to see and should be used to determine the presence of this insect. |
