About Lymantria moth

Lymantria moths (formerly referred to as gypsy moths) are a threat to B.C.'s ecology and economy. The insect attacks both forests and urban trees. The presence of moths in a jurisdiction poses a quarantine challenge and a potential threat to the endangered Garry Oak ecosystem in southwestern B.C.
