David DutkiewiczGuest Speaker: David Dutkiewicz

Topic: Gypsy Moths in Ontario


2020 was a banner year for gypsy moth deforestation in Ontario – the worst ever! This is an invasive moth that, in earlier life stages, has a huge appetite for a variety of trees and shrubs. Attendees of tonight’s presentation will learn why the gypsy moth deserves our attention, the moth’s life stages and techniques we can employ in our gardens to help reduce the population.

David Dutkiewicz is an Entomology Technician with the Invasive Species Centre (, working in the insect diagnostics lab at the Great Lakes Forestry Centre in Sault Ste. Marie. David earned a Master of Science degree in Environmental Science from the University of Guelph and his professional work is focused on forest pests and invasive species, with a specialization in beetles and moth/butterfly larvae.
