Water boatman

6946.             These insects were found late at night 11pm/12am. They were all around the window trying to get into the house. About 20 of them did find their way in the house crawling on the ground and flying around the lights. About 5-10mm long with 4 legs and possibly 2 more small ones under the front portion of the body. The day had been warm (July 6the about 20 degrees all day). A light rain in the evening for about an hour. Please let me know if you need anything else from me. Thank you. St.Albert, Alberta. Canada
