The adults are brownish to black weevils with a robust body and a blunt short snout. They can be distinguished from alfalfa weevils, which may be present at the same time, by the short snout and the lack of a medium brown strip down the back. The egg are seldom seen, but they are small oval and whitish when newly laid then turn black in a day or two. The newly hatched larvae are small plump white and grub like. Larvae pass through five instars before pupating. The larger late instars are about 1/10 inch long and cream colored with a brown head. Unlike the alfalfa weevil, clover root curculio larvae have no legs behind the head capsule.
