Switzerland, a long, long time ago ...

The male mazarine blue is unmistakable with his lead blue upperside and broadish wing borders. In both sexes the underside is also characteristic, being like an oversized little blue, lacking the orange markings found on so many blues.

The species is common throughout much of Europe, though absent from Britain. In Switzerland you may bump into a mazarine blue on almost any patch of grassland or roadside verge from May onwards - sometimes earlier.
