Found this funny guy on the sidewalk while out for a walk. Fascinated by him. Spotted in New York. Thank you in advance :]

Hello, yesss, this is a robberfly called the Northern Hammertail (Efferia aestuans), family Asilidae.

The males have a hammerlooking reproductive structure at the end of the abdomen, this looks like a female.

Lady robber fly. Enormous. Scary.

I was under attack by a scoundrel insect, a bloodsucking deerfly. She buzzed haphazard circles around my head, searching for the perfect opportunity to alight and painfully stab into my flesh to drain my fluids.

a benevolent robberfly, a raptorial guardian angel of the genus Efferia, swooped in and took care of the problem in a swift and professional manner, with neither cruelty nor mercy.

Gonna also be posting all my bug encounters from the last few weeks. Here’s a robber fly! Efferia astuans.

This second photo is from an earlier day where it’s carrying prey!
