6590. I found this large flying insect in my pool and had never seen one before in my area. It was nearly 2 inches long. After some research I believe that it is a Pigeon Tremex. While it was recovering from being in the pool (near death unfortunately), I took this photo. Holland Landing is in central Ontario near Newmarket and in my over 50 years of living here, I have never seen one before. Holland Landing, ON. Canada
Number 6590. This is indeed a pigeon tremex, Tremex columba (Hymenoptera: Siricidae). Click here for details on its life history.
