CLOSED: Fly with Spike Tail?

Indianapolis, IN(Zone 5b)

I thought this was a horsefly, but after looking at pics of them (amazing pic, btw, bebop), maybe it isn't. They don' t have the spike at the tail end that this thing has. Anyone wanna tell me what this is?

I thought that thing was a stinger, but it looks like horseflies bite with the stuff up front.

Oh, we found it! It's some sort of robber fly.

Glad it isn't a bot fly - gross! Thanks, though. :o)

It might be Promachus fitchii- Bee Killer/Giant Robber Fly.
