Miletinae is a subfamily of the family Lycaenidae of butterflies, commonly called harvesters and woolly legs, and virtually unique among butterflies in having predatory larvae. Miletinae are entirely aphytophagous (do not feed on plants). The ecology of the Miletinae is little understood, but adults and larvae live in association with ants, and most known species feed on Hemiptera (aphids, coccids, membracids, and psyllids), though some, like Liphyra, feed on the ants themselves. The butterflies, ants, and hemipterans, in some cases, seem to have complex symbiotic relationships benefiting all.

Miletinae in the context of Lycaenidae
Lycaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species.
The family comprises seven subfamilies, including the blues (Polyommatinae), the coppers (Lycaeninae), the hairstreaks (Theclinae), and the harvesters (Miletinae).
