I saw this bug today, and I thought it was a dragonfly. None of the pictures I pulled up on Google images matched this bug. It had a thick black body, dark wings, the length of the bug was about 3 inches. It kind of hovered the way dragonflies do, looked menacing but left me alone. I couldn't get a picture of it, but I'm wondering if even with these sketchy details if someone might know what it could be.
