Hi Kerry - I think this is Ommatius sp Common Yellow Robberfly. This is the first time I've seen them mating. Note the kick out half way down the leading edge in the males? wing. I've noticed this difference before and was wondering if I had photos of two different species. Nice to see that it is sexual dimorphism.

Robber Flies are a difficult group to ID to genus with confidence (in my experience, anyway). However, I agree that this lovely pair certainly look like Ommatius - let's call it. ALA museum images show what appears to be identical wing venation AND the same sexual dimorphism in the wing that you identified!
