This is the time of year to monitor your trees and scrape off Ldd moth egg masses. Help us beat last year’s total of over 12,000 egg masses scraped across Ontario!
The Invasive Species Centre is holding its second egg mass scraping contest with the goal getting residents of Ontario out monitoring their properties and removing Ldd egg masses!
We’re calling on community members across Ontario to become community scientists by help us limit the spread of Ldd moth, one egg mass at a time.
Already scraped your egg masses? Enter the contest!
What is the Ldd Moth?
The Ldd moth (formerly the European gypsy moth) is native to Europe and is currently established in northeastern United States and eastern Canada. This insect is a significant threat to Ontario trees, and has gained widespread attention over the past year for the heavy defoliation seen across the province. The caterpillars feed on crown foliage of a wide range of hardwood and some softwood trees, which makes it a defoliating forest pest of concern.
Hosts trees include oak, birch, aspen, sugar maple, American beech, and softwoods including eastern white pine, and Colorado blur spruce (Gypsy moth, Ontario.ca).
The insect lays its eggs on the trunks and branches of most trees in masses of 100-1000 eggs during the months of June to the following spring, so now is the time to start scraping!
By removing the eggs this year, we can help limit infestations in forthcoming years, and help protect our forests from defoliation!
Always wear gloves and protective glasses when scraping egg masses from the tree.
