I have a penchant for taking photos of insects while up at the cottage. Last week I had the pleasure of meeting this amazing guy/gal. After the second shot it decided to leave and flew across the lake to the other side. From your site I believe it to be a water scorpion, the first I have seen in the Haliburton/Minden area just south of Algonquin Park in Ontario, Canada.
Thank you for your high quality image of a Water Scorpion in the genus Ranatra.
