This year has seen a rise in the number of Lymantria dispar dispar or LDD moths (also known as European Gypsy Moths) and LDD caterpillars, which affect native maple trees as well as other species. In areas with severe outbreaks, “trees and shrubs are completely defoliated over large areas; despite the trees’ ability to produce a new crop of leaves over the summer, the damage causes significant growth loss” (https://www.ontario.ca/page/gypsy-moth)
One effective way to reduce the spread of this invasive pest is to collect and destroy their egg masses before they hatch.
The Invasive Species Centre and Eastern Ontario Model Forest are currently running a contest to encourage residents to remove LDD moth egg masses from their trees. They hope to limit the spread of the destructive caterpillars and moths by working together to collect 500 or more egg masses across Ontario. There are even prizes being offered as incentive to collect as many as possible!
