The Lycaenidae as construed here includes the blues, coppers and hairstreaks, but not the metalmarks, which are viewed as a sister-family Riodinidae, based on the combined phylogenetic analysis of morphological and molecular data by Wahlberg et al. (2005). The vast majority of lycaenids are in the clade that includes the blues (Polyommatinae), coppers (Lycaeninae) and hairstreaks (Theclinae). Eliot (who viewed these taxa as tribes of a more inclusive Lycaeninae in Corbet et al. 1992) implied that Aphnaeinae is the sister group to the other three subfamilies based on characters of the larval head capsule.
