Tremex columba

Ottawa City Ontario Canada I was looking at my collection of picture and I found this one. It is called Tremx columba. I was cleaning out the garden one day and she was there. I thought it was a dragonfly. Nope, not! I ask friends around and Telsing said, it is a Tremex columba. I thought it was a neat find, considering I am in a city garden. The date of the photo is August 8, 2015.
