Both in lowland and mountains, the Baltic Grayling occurs in peaty and swampy habitats. Most butterflies are found in damp habitats with a vegetation of grasses and sedges, often with open water in the middle and surrounded by coniferous woodland. The butterflies frequently visit the wood edge looking for flowers, because the peat vegetation is poor in nectar plants. They also rest on the branches or trunks of trees, or on dead wood. The Baltic Grayling shares its habitat with hardly any other butterfly. The female lays her eggs on various grasses, but which ones the caterpillars feed on is not known. The caterpillar’s development takes nearly two years.
