I have this insect that seems to have made it’s home near the entrance of our apartment building. I’ve seen it crawl into the cracked cement where the sidewalk meets the stoop.
It looks somewhat like a wasp, but it’s almost completely black. The only part that isn’t black is the underwing (?), which is green. Grass green. It is about 2 inches long. The basic shape of it is like a wasp, even with the longish hanging back legs and nearly disappearing ‘waist’, but it’s still thicker around. I’ve never seen a bug like this. I live in Southeast Quebec, in Canada, if that could help with identification.
