Bombycilloidea is a superfamily of passerine birds that contains ten living species. They are found in North, Central America, most of the Palearctic, the Arabian Peninsula, the islands of Hispaniola and Sulawesi, and formerly the Hawaiian Islands.
== Taxonomy == The superfamily includes only ten extant species. It is sister to a clade containing Muscicapoidea, Certhoidea and Regulidae (both clades are contained within the parvorder Muscicapida), from which it diverged during the mid-late Oligocene, about 25 million years ago. The common ancestor for both clades lived in Eurasia; at some point, the ancestral Bombycilloidea arrived in North America where they rapidly radiated into multiple families. One of these lineages moved back into Eurasia, where it gave rise to several lineages that stayed in Eurasia or colonized Wallacea or Hawaii.
