(Maygen, 1830)
Silvery Argus
Description:
The Silvery Argus occurs on flower-rich grasslands with some bushes or trees, in grass along the hedges, at the edge of woodland, and in sunny, grassy woodland clearings. The grassland on which the Silvery Argus occurs is usually damp and high, but it is also seen on dry grassland.
The female lays her eggs on the flowers of Wood Crane's-bill (Geranium sylvaticum) and Meadow Crane's-bill (G. pratense). The caterpillars eat the leaves as well as the flowers. They are attended by ants.
In Spain and Sweden, this butterfly probably hibernates in the egg stage, and in the Alps as a chrysalis.
