Okay, you guys know I'm a butterfly gardener and I'm always keen to know who is friend and who is foe. This guy is definitely foe as he has a Dainty Sulphur in his mouth!!! Grumbling I don't recall seeing these before, but there are a lot of them this year. Whatever they are, perhaps this is just a good year for them and I never noticed before now? They do fly very fast which explains why it was able to catch a Sulphur and why I couldn't step on it. So what is it?

It's a Robber Fly in the family Asilidae. Females need the protein for their eggs.

I would say it's a Machimus species but they are difficult to get to species.

I know, it's sad!

They will eat other flies and robberflies too.

It's gruesome when you see a freshly caught fly struggling to escape, with a feeding tube stuck in it slowly being sucked dry.

Robberflies are pretty common here and this is probably about the time I usually start seeing them, they emerge from the ground where they overwinter as larva. They'll perch on something vertical where they can see everything. I often see them clutching their prey...most any insect they can get.

I have seen them perching on some of my plants. That's the only butterfly I saw that became a victim, fortunately.

I think I saw another one but I didn't want to confuse the post with two different insects, if they were. Is this also a Robber Fly?

Yes that is a Robberfly, from the appendage on the tail end it looks to be a male.
