Brownie or Browning ♀

The genus Miletus Hübner 1819 is distributed from India to south China and through the Malay Archipelago and Philippines to New Guinea, it has been well known as a true SE Asian genus because most of all the previously known species within the genus are mainly distributed in the principal part of SE Asian subregion, with a few species extending to the north as far as south China but are not endemic there.

Butterflies of the subfamily Miletinae (commonly called harvesters and woolly legs) are virtually unique 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. (Wikipedia)
