This Gentle Giant was found crawling in the grass. My husband let him crawl on his hand (as you can see from the photo). It’s very big, about 2.5 to 3 inches long and approx. 1.5 to 2 inches wide. I live in Ottawa, Ontario. I’m not sure what kind of bug this is, I’m guessing it’s some type of beetle. Just wondering if it’s a bad bug or a beneficial bug to have around? I have a vegetable garden near by. Your help with its identification would be greatly appreciated. Many Thanks, Pam
Looks like you have a predacious diving beetle, genus Dytiscus.
The adults will fly to lights at night so perhaps that is probably why you found it in the grass. The larvae are sometimes called water tigers. Both the larvae and adults are predaceous and feed on fish, mosquito larvae, other aquatic invertebrates, and sometimes tadpoles and salamanders.
