Asian Gypsy Moth
Lymantria dispar asiatica

Asian Gypsy Moth (Lymantria dispar asiatica) is an insect pest of hardwood trees. It is a native of Asia and was first detected in Washington in 1991.

Ongoing and completed eradication of various sites in western North America have so far prevented the establishment of this generalist feeder. Gypsy Moth is just one of many forest pests that are moved to un-infested forests by humans moving firewood. Help to protect our forests: don't move firewood!

This insect pest has been identified by USDA-APHIS as a serious threat to US Agriculture and Natural Resources, and surveys have been planned for multiple states.
