Aculus
Aculus is a genus of eriophyid mites (Eriophyidae: Phyllocoptinae) comprising numerous species that are predominantly plant-associated. Species in this genus exhibit diverse host relationships, with documented associations spanning at least 15 plant families including Rosaceae, Salicaceae, Fabaceae, and Hypericaceae. Most described species are vagrants on leaf surfaces, though some form galls or cause leaf deformation. Several species are economically significant agricultural pests, while others have been investigated for biological control potential against invasive plants.
