plum curculio
The plum curculio (''Conotrachelus nenuphar'') is a true weevil native to the regions east of the Rocky Mountains in the United States and Canada. It is notorious for destroying fruits if left uncontrolled.
== Life stages ==
A female curculio uses a number of hosts to lay her eggs in, including plums, peaches, apples, pears, and other pome and stone fruits. After the female has chosen a suitable host, she will build an egg chamber under the fruit skin to receive the egg. She then turns around and places the egg in the cavity. Next, she slices a curved slit underneath the egg cavity, leaving the egg in a flap of flesh. Eggs that do not hatch are killed by pressure from the growth of the host fruit, leaving crescent-shaped scars visible on the outside of the fruit.
