Greya politella
Greya politella is a small moth in the family Prodoxidae distributed across western North America from southern British Columbia to southern California and inland to Idaho and Colorado. It participates in a nursery pollination mutualism with Lithophragma flowers (Saxifragaceae), in which females pollinate flowers while ovipositing into them; larvae subsequently develop as seed parasites within the host fruits. The species exhibits deep phylogeographical structure with genetically distinct populations across multiple regions, shaped by glacial refugia and post-glacial expansion.
