Polyommatus erigone is a butterfly in the family Lycaenidae. It was described by Grigory Grum-Grshimailo in 1890.
Seitz: "erigone Gr.-Grsh. (80), from the Pamir, is considerably smaller [than eros]; beneath the ocelli are less prominent and the white streak of the hindwing is very distinct. Also the female bears a superficial resemblance to icarus, whose blue colour is almost exactly the same as that of the erigone males; obtained at a considerable altitude (13,000 ft.)."Seitz.
