Strepsiptera

Strepsiptera, peculiar insects referred by some to a special order, ranked by others among the Coleoptera. The females are blind and worm-like parasites, living inside various bees and wasps, but the adult males are free, with small twisted fore-wings and longitudinally-folded hind-wings. The larvæ, hatched within the adult bee or wasp, emerge and infest the grubs.
