Ah, romance. Because insects are so numerous, a good deal of work goes into finding a suitable mate. Females can be fickle, with such a wealth of insect bachelors from which to choose. If a male stands a chance at passing on his genes, he's got to do something to stand out in the crowd. Courtship rituals in insect mating include serenades, dances, nuptial gifts, physical touch, and even aphrodisiacs.

The evolution of courtship is a rather sophisticated form of insect behavior. In general, courtship is rare in the insect world and the few male insects that do solicit mates -- lightning bugs by flashing, crickets and grasshoppers by calling -- are well-known exceptions. The males of many robber fly species court their mates, although others that rank lower on the evolutionary totem pole do not.

The females of some robber fly species are cannibalistic, albeit unintentionally so. "Courtship behavior seems to have evolved as a way of reducing the male's risk of being eaten by a female of his own species," Dr. Lavigne has concluded. He explained that cannibalism is almost exclusively a female trait that apparently results from a case of mistaken identity, since a hungry robber fly considers any insect smaller than itself to be potential source of sustenance.

By courting the female before getting close enough to mate, a male with amorous intentions in effect announces that he is neither predator nor prey but merely interested in propagating the species.
Often, female robber flies play hard to get, while the male ferociously vibrates his wings and elevates his body. This allows the female to recognize that (a) they are the right species, and (b) that they are of the opposite sex.
"Okay, Okay…can we at least hold hands?"

Lastly, (thank heavens) -
Death feigning is exceptional in the context of sexual selection. We are aware of one example of this performed by female robber flies to avoid male harassment.
(Women will recognize this as the old "pretend you're asleep trick".)
