Lanark Council hears update on local Gypsy moth activity

by | Aug 27, 2020 | Local News | 0 comments

At Wednesday’s public works committee meeting of Lanark County council, members in virtual attendance heard a report on Gypsy moth activity in the area from Hillary Fleming, a climate/environment intern. 

According to Fleming a single Gypsy moth can consume up to a square meter of foliage during its life stage. An egg sac of only 50 can defoliate an adult tree to the point where it’s mortality is certain.

She noted that the last major outbreak was 30 years ago, but climate change, bringing warmer winters and more humid summers, had improved the moth’s ability to reproduce and wreak havoc on the region’s forests.

She added that the Ministry of Natural Resources and Forestry was conducting aerial surveys this summer and will provide a report later this year regarding defoliation levels and the health status of the forests.

She provided advice on recognizing and removing egg sacs and caterpillars along with some safety tips on how to
be protected from the adverse effects of contact with the insect’s fine hairs.

Those can be found at the county’s website at
