The plum curculio (Conotrachelus nenuphar) is a true weevil native to the regions east of the Rocky Mountains in the United States and Canada.

A female curculio uses a number of hosts to lay her eggs in, including plums, peaches, apples, pears, and other pome and stone fruits.

Adult plum curculio are about 4 to 6 mm long and have a small, rough snout colored with black, gray, and brown specks.

In badly damaged fruit, one can identify large scars and bumps due to feeding.

An important preventative measure is destroying the fallen, damaged host fruits before the adults emerge.
