Achrysocharoides
Achrysocharoides is a genus of small parasitoid wasps in the family Eulophidae. The genus was erected by Girault in 1913 and includes species distributed across Europe, North America, and the Oriental region. Members are known for their specialized parasitism of leaf-mining moths in the family Gracillariidae, particularly Phyllonorycter species. The genus exhibits unusual reproductive strategies, including split sex broods where male and female offspring develop in separate host individuals—a trait rare among parasitoid wasps and virtually restricted to this genus.
