Biology. In mountains and northern Europe this species is restricted to sphagnum mires and wet peaty meadows. Nests are often situated in grassy tussocks with a built up cone of sphagnum and grassy fragments. In Central Asia including Mongolia and parts of the Himalayas a morphologically indistinguishable form of this species is abundant but inhabits an entirely different biotope on dry stony ground. However, according to Kutter (1977) F. » piceaHNS « also nests on dry land in the High Alps. Alatae occur in July.
