European Gypsy Moths are a non-native invasive forest defoliating insect from Europe that was brought to North America in the 1860s. 

According to the Ministry of Natural Resources and Forestry, “They were first detected in Ontario in 1969, with widespread defoliation occurring in 1981. Gypsy Moth outbreaks occur every 7 to 10 years when larvae (caterpillars) chew holes in leaves or devour entire leaves.”

There are online resources, from both Simcoe County and the Ministry of Natural Resources and Forestry, that concerned residents or landowners wanting to manage European Gypsy Moth impacts can consult, including management guides.
