Hindwing: anterior or costal third to half and apex brown; a slender black anteciliary line, beyond which the cilia are as in the forewing. Brownish grey. Forewing: a short, transverse, dusky lunule on the discocellulars... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Lesser Grass Blue is recorded against all the insects logged in Danum Valley Conservation Area (7 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
