Asian spongy moth

Lymantria dispar asiatica

Asian spongy 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!
