Cicada Killer Wasp, perhaps?
I just learned about these bastards this year, as I'd never even seen one before. Now I'll be chillin' on the deck, listening to a cicada or two, when a fkn huge wasp/Cessna flies by my head and into the small tree by the deck... and suddenly the cicada noise stops. A minute or two later and a dead cicada drops from the tree, and the wasp continues on his merry way.
