Brassy ringlet

Species of butterfly

The brassy ringlets are a species group of ringlet butterflies in the genus Erebia. Though closely related, their monophyly is not completely resolved. Still, the brassy ringlets are taxa similar to E. tyndarus – the Swiss brassy ringlet –, and in many cases certainly close relatives. A notable trait of their genus is an ability to adapt well to cold and somewhat arid habitat, like taiga or regions with alpine climate. Optimal habitat in Eurasia, where most of the brassy ringlets are found, therefore occurs in two distinct belts – in the very north of the continent and in the Alpide belt – in interglacials, and in glacials in one periglacialic belt at lower altitude, in places interrupted by dry wasteland and deserts.
