This winged insect found its way into my house while I was putting the dogs out. It looks like something between a wasp and a mayfly. I’ve been checking out bugguide.net but can’t find anything that looks much like it. The picture isn’t great but my camera won’t do an extreme closeup. Hope it’s enough.
It looks to me like an ichneumon wasp, aka ichneumon fly.
I think you’re right. It did have a hymenopteran-looking body. Next time I’ll try to find something more difficult.
