Here's the thing, a few months ago we had grasshoppers all over and what I've noticed is these wasps... I don't even know how to describe it. They sting (I assume) the grasshopper and then move around with it. Like the black wasp thing is on top of the grasshopper (who I can't imagine is still alive) and kind of puppets it around. It was the most terrifying thing I'd ever seen as it looked straight out of a horror movie or re4. I don't even understand what it was doing or why.
Might have been laying eggs inside it. Some types of wasps do that. Then the babies eat their way out.
