The emerald ash borer is continuing its spread across the region.
"We are starting to see exit holes in the trees in areas we hadn't seen them before so that tells us the pest is there," Donna Lacey, forestry technician at the Saugeen Conservation Authority, said Thursday. "In some cases people are actually catching the insect."
Lacey explained that in the past people had brought other insects they thought were ash borers such as six-spotted tiger beetles and click beetles, which have similarities to emerald ash borers, including their shiny emerald colour. That has changed this year.
