The short-tailed blue or tailed Cupid (Cupido argiades) is a butterfly that forms part of the family Lycaenidae. It is found from Europe to Japan and in India. The male has a violet upperside, a violet forewing with brown edging, and a violet hindwing with a brown edging of varying length. The wings have black spots, some of which have slight white edging. The tail is black with a white tip. The underside of the wings are white or brownish grey, the markings prominent or very faint. The antennae are black with white speckling on the shafts. The body is brown with a purple flush on fresh specimens.
The female has a dark grey-blue upperside, with black parts and broader edging. The undersides of the wings are like those of the male but with more stark markings. The body is like that of the male but without the purple flush.
Specimens from very dry localities in Upper Burma and from Great Nicobar Island are remarkably small and pale, with the markings on the underside, especially the subtornal ochraceous yellow patch, more or less obsolescent.

GBIF citizen-science records
It is estimated from how often the Short-Tailed Blue is recorded against all the insects logged in Daegu (6 verified sightings), 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.
