Hello and thank you for contacting the Douglas County Master Gardener program. In looking at the photo that you submitted, I was unable to verify that it was an Emerald Ash Borer. I first looked in the " Gardner Insects of North America", second edition, page 434. I then used Google to find some pictures that I have attached.
Another great resource is the Colorado State University Extension Office. They have a very good library of useful information related to all kinds of gardening topics. I have attached the fact shee related to the emerald Ash borer. https://cmg.extension.colostate.edu/emerald-ash-borer-resources/ .
I hope this information is helpful.
Thank you for contacting us.
