The female midge liquefies her mate’s insides during the sexual act with juices secreted from her proboscis.
The midge, a kind of fly, eats its mates. The female midge grasps and stabs her mate’s head with her proboscis while in sexual union. During mating, the female midge's secretions liquefy the insides of the male’s body which allows her to ingest him. After the mating she drops her mate and his penis breaks off, remaining inside of her.Source:Wangberg, James K,2001, Six Legged Sex.
