Gypsy Moths

Posted in the Announcements page 14 days ago on Monday, June 07, 2021.

Gypsy moth (Lymantria dispar) is an invasive species that is severely weakening trees across North America.

Gypsy moth outbreaks occur every 7 to 10 years. Gypsy moth caterpillars (“larvae”) will chew holes in leaves, and may partially or totally strip a host tree of its leaves.

During outbreak years, nearly all broadleaf (hardwood) trees may be completely defoliated. This can harm and even kill otherwise healthy trees.

The first hatches of this year’s Gypsy Moth larvae were observed in London on April 29.

The Invasive Species Center and the Upper Thames River Conservation Authority have put together some resources on how to deal with Gypsy Moths on your property.
