Damp grassland, at the edge of bogs or streams, is the habitat of the Dusky Grizzled Skipper, although they sometimes occur on dry grasslands. The male show marked territorial behaviour. The female lays her eggs on various species of cinquefoil (Potentilla spp.), such as Tormentil (P. erecta), and Alpine Cinquefoil (P. crantzii), and also on Sibbaldia species. She prefers plants growing on drier places, such as on hummocks in damp habitats, or at a little distance from its habitat. The caterpillars live hidden between spun leaves, and it is in this stage that the Dusky Grizzled Skipper hibernates. The development takes two years.
