Moths of Block Island (Rhode Island, USA) I: Zygaenoidea

As a result of surveying effort since 2015, I herein report 7 species of Zygaenoidea from Block Island, a small offshore island in southern New England with a history of intensive agricultural use. I quantify species phenology and local abundance, compare the island's fauna to those of nearby landmasses and the broader region, and discuss possible future colonization of Block Island by additional species as well as the likely factors behind the composition of the island's zygaenoid fauna.
