Nasonia
jewel wasp
Nasonia is a genus of small pteromalid parasitoid wasps comprising four described species: N. vitripennis, N. giraulti, N. longicornis, and N. oneida. These wasps are ectoparasitoids of fly pupae, primarily targeting blow flies and flesh flies. The genus has become a prominent model system in behavioral genetics and evolutionary biology due to its short generation time, ease of laboratory rearing, and the ability to hybridize species in controlled crosses. Nasonia wasps exhibit a distinctive emerald sheen on their exoskeleton, earning them the common name 'jewel wasps.'
