16 species in 10 genera are known from Block Island. Moths in this family have a highly distinctive appearance characterized by very long, skinny legs and narrow, deeply lobed wings tightly folded together and held at right angles to the body. The island’s fauna was treated by Hunt and Matthews (2020); note that two species have been added to the island list since then.
