Like all ringlets, the Lapland ringlet has eyespots surrounded by a red or reddish yellow area. It flies around bogs, which is unusual among its close relatives with the exception of the Arctic ringlet. The Lapland ringlet can be differentiated from the Arctic ringlet and other ringlets (except the Arran brown) by the white blotches on the underside of the wing. The Arran brown can be differentiated from the Lapland ringlet by the fact that it is lacking continuous red strips on the upper side of its wings.
The Lapland ringlet can be found – though not very commonly – in most of Finland (excluding the Åland Islands and Finland’s north-western “arm”). The species has disappeared from large areas of southern Finland since the 1980s. The Lapland ringlet varies in abundance in a biennial cycle (like the Arran brown) because of the way that it overwinters twice. In southern Finland it is more common in oddly-numbered years. Females lay their eggs e.g. among moss close to the foodplant.
