Robber fly

The first shot of the head is simply amazing! The detail on the eye absolutely fantastic.

I've never seen one in person, but I have a photographic memory for almost any kind of animal I"ve seen in a book or documentary. The name just popped out and I looked it up

I think Karen has it.

I don't think so because it appears to only have one set of wings as opposed to 2 in dragonflies. I think its a type of fly.

No idea what this is but it's really interesting how it rests it's wings. Brazil has an amazing diversity of wildlife. I was just there this past winter.
