** NEW INFO FROM COM ED –
VEGETATION MAINTENANCE
First found in Michigan a few years ago, this insect has no natural predators and has been eating its way across the Midwest, being found in Illinois earlier this summer. Current locations where its presence has been verified include Kane County, Evanston and Wilmette along the lake shore.
The Department of Public Works has received numerous calls about the Ash Borer, |and has investigated many insects residents thought might be the EAB.
The Emerald Ash Borer is rather distinctive in appearance, the adult stage looking
very much like a small, green grass hopper more than a beetle or June bug. Communities and tree lovers are very concerned about the possibility of the EAB gaining a foothold here as over 20% of the trees in the Chicago area are Ash trees. This insect could wrought as much or more damage on neighborhood trees as the Dutch Elm Disease did in the 1960’s and 1970’s.
Below are photo’s showing the Emerald Ash Borer in both its larval and adult phase. If you believe you have found an Emerald Ash Borer, please contact Public Works at 847-746-4050.
