Giant Water Bug

Bug Identification
I live in Nova Scotia, Canada and I took this photo by a stream in my neighbourhood. I have looked on your site and it appears to be a giant water bug, but this one was only approximately the size of a thumb nail. I have grown up around brooks and lakes and this was the first and only time that I have ever seen one of these bugs. Is it possible that it’s just an immature bug or this is a different species altogether? Thanks.

Hi Lindsay,
Not only are there different species of Giant Water Bugs, there are different genera as well. This looks like a member of the genus Belostoma whose representatives are much smaller than those in Lethocerus.

  1. We found large beetles falling around our house. I have a video of one. I have asked online and am being told ‘water beetle’ but from what I can tell it doesn’t look like them at all. It is shiny and oval shaped. Seemed only to crawl, no flying. I would love to send you the video and see what you think.
