Annulipalpia is a suborder of Trichoptera. The name of the suborder refers to the flexible terminal segment of the adult maxillary palps, which often has many tiny rings. The larvae construct fixed retreats in freshwater aquatic environments. Most of the families are unique in spinning silken nets for filter feeding.
