2 species in 2 genera are known from Block Island. All Nearctic representatives of this family are black, some with red or orange markings, and many are diurnal. The local fauna of this family is briefly discussed on the post for the superfamily; refer to my 2021 paper on the Zygaenoidea of Block Island for more detail.
