I found it! Robber fly. It was not afraid of humans at all.

AKA "assassin fly" ... SCARY ASSASSIN

Looks like a Mosquito. Hit it with RAID

it was in a city park

Did it rob and/or assassinate you, or anyone that you know of?

Nope, it just watched the birthday party.

Lovely photo!

And he's kinda cute

He turned towards me when i moved in to get the pic.

he does look a little like Madonna
