Derelomus
Derelomus is a genus of weevils (Curculionidae: Derelomini) distributed across the Afrotropical and Mediterranean regions. The genus comprises 32 recognized species, organized into four main species groups based on morphological and molecular data. Species exhibit specialized brood site pollination mutualisms with host plants, with different species groups associated with distinct plant families: Fabaceae (Vachellia), Achariaceae/Ebenaceae, Strelitziaceae/Arecaceae (Strelitzia and Phoenix reclinata), and Arecaceae palms (Chamaerops, Cocos, Phoenix). Adults are small weevils with rostrate heads typical of the family.
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.
