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.
