Weevils
More than 2,500 species of weevils have been identified
from North America. Weevil adults are characterized by a
broad, beak-like snout. Most weevils are 4 to 10 mm long,
slow-moving and dark-colored. Adult feeding damage often
appears as a crescent-shaped notch cut out of the leaf
edge. Many weevil larvae (root weevils) feed on plant
roots in the soil. Larvae are white, legless, C-shaped
grubs. Weevil grubs can be distinguished from scarab
grubs by their lack of legs. Some weevil larvae, such as
white pine weevil and root collar weevil, develop under
the bark of shoots or trunks.
