Twisted-wing Parasite

Xenos vesparum

Inside living paper wasps across southern Europe and the Mediterranean

Weird but real

The female never leaves her wasp host — she's a headless, legless bag of eggs fused into its abdomen, mating through a tiny hatch.

Why it's cool

A parasite that hijacks a wasp into a roaming nursery, then sends out fan-winged, raspberry-eyed males that live a few frantic hours to find her.
