Three more photographs from my trip to Oregon, for those who like robber flies. I just love these beasties.

Mating robber flies (Promachus princeps, I think) on rabbitbush. Female is holding some type of cerambycid (perhaps Crossidius hirtipes), which she probably caught prior to the male approaching. I don’t think it was a nuptial gift from male (though that was my first thought). Female robber flies have been observed eating males, which are smaller, so waiting for a female with a meal is a good strategy for males who want to love and then live some more. Female robber flies with meals in hand are also less likely to resist mating attempts. Madras, Oregon.
