Satyrus effendi is a butterfly of the family Nymphalidae.

[1][2] It is found in the southern Zangezur Mountains (including both the Armenian[3] and Nakhichivan sides).

It inhabits sub-alpine grasslands, occupying stony slopes on 2500–3000 meters above sea level.

The range of Satyrus effendi is covered by the Lichk Prime Butterfly Area,[4] that is included in the Zangezur Biosphere Complex.

The butterfly was featured in an episode of National Geographic's podcast Overheard at National Geographic,[5] in which photographer Rena Effendi discusses how it was named for her father, a lepidopterist from Soviet Azerbaijan, as well as the difficulty in finding live specimens due to it being located entirely on the hostile border between warring Armenia and Azerbaijan.
