Additional file 1: Figure S1. of The pivotal role of aristaless in development and evolution of diverse antennal morphologies in moths and butterflies

Antennal morphology and phylogenetic tree of all lepidopteran families and superfamilies. The phylogenetic tree is based on the molecular phylogenetic estimation by Regier et al. [49]. Antennal morphology of each family was quoted from Scoble [8]. Antennal morphology of each family was categorized with the indicated color code in the upper left of the figure. The prominent bipectinate lateral branch appears to be acquired independently at least three times in the linage leading to swift moths (Hepialidae), bagworm moths (Psychidae), and the large group including Obtectomera and Cossoidea + Sessoidea + Zyaenoidea. Due to insufficient description or discrepancy between morphological classification and molecular phylogeny, several descriptions were redundantly quoted in distant families as below. (*) The same description in Papilionoidea was quoted. (**) The same description in Copromorphidae was quoted. (***) The same description in Megalopygidae was quoted. (****) The same description in Zygaenidae was quoted. (*****) The same description in Choreutidae was quoted. (TIFF 437Â kb
