For #insectSaturday / #insektenSamstag - have some miscellaneous #robberflies, with prey, from earlier this year.

Edit: *not* robber flies, but dagger flies instead? Possibly Empis livida:

Quite a good photo given the circumstances – and a steady pulse!

Just yesterday I stumbled upon a Machimus robber fly, but it's unclear which species it is exactly. Caught it in the act of consuming a small solitary bee:

Bugs? Yes. From the last day or two!

Absurdly fluffy bumblebee on a crocosmia; robber fly with its hoverfly (?) prey; Red Admiral butterfly; metallic fly not actively waggling its white-tipped wings at another fly.

ID'd my first ever robber fly - Stenopogon inquinatus. I might have seen them before, but learning to observe is a different matter altogether.

Some sort of robber fly -- perhaps Laphria flava?

Spotted in #Goettingen, Germany. Phone photos only, unfortunately.

And I'm intrigued to know whether these #RobberFlies (#Asilidae) have ribbed wings for the same reason.

I found a dead Beelzebub Bee-Eater (Mallophora leschenaulti) on the ground today! Poor bug has seen better days, but there's a remarkable new species for the life list.

Robber flies are superb hunters—their visual acuity is also the stuff of legend:
