Miletinae

Miletinae is a subfamily of the Lycaenidae family 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.
