Chequered Skipper Butterfly
Download a pdf copy of this Information Note
This small, fast-flying butterfly is now restricted to damp grassy habitats in a few places in western Scotland. The butterfly breeds on open damp grassland, dominated by tall Purple Moor-grass. Favoured sites are on the southern edges of open broadleaved woodland as richer soils produce a lusher growth of the foodplant.
- Grazing is not essential but the sites must remain scrub and bracken free.
- Warm and sheltered sites are important
- These butterflies are probably under recorded. If you spot any send your record to Butterfly Conservation Scotland.
Chequered Skipper generally require
- In Scotland, the butterfly breeds on open damp grassland, dominated by tall lush Purple Moor-grass. Favoured sites are often south facing on the edges of open broadleaved woodland, as richer soils produce a lusher growth of the foodplant.
- It’s entire UK population occurs in Lochaber and north Argyll, where there are around 50 colonies.
- The main foodplant in Scotland is Purple Moor-grass (Molinia caerulea) found in sheltered woodland edges or glades in South Lochaber and North Argyll.
- Adult Chequered Skippers are usually on the wing from the third week of May until the end of June. Adults tend to congregate where there are lots of nectar plants; they are particularly fond of bugle, bluebell and marsh thistle. Choose a sunny, warm and if possible calm day and look for them in sunny sheltered areas.

Management Requirements to Benefit Chequered Skipper Butterflies
- The ideal management of Chequered Skipper sites is light grazing. This helps keep glades open whilst also keeping areas flower-rich. Heavy cattle grazing can be detrimental to the site as the butterfly likes lush Molinia grassland. Livestock are not essential but the site must be kept open of scrub and bracken.
- Low-levels of deer browsing can be particularly important at keeping scrub in check if there is no cattle grazing
- It is sometimes necessary to control bracken to prevent excessive encroachment into both nectar plant areas and breeding areas. The maintenance of open space within woodlands allows Chequered Skippers to fly between colonies.
- Rides and paths running east to west have a greater proportion of warmer south-facing edges. The inclusion of scalloped bays at intervals along the south-facing edge provides additional sheltered habitat.
- The main threats to remaining populations of the butterfly are inappropriate management, or lack of management, leading to loss of colonies; and fragmentation of the habitat between colonies, causing isolation. This is important for species like the Chequered Skipper which exist in a metapopulation, i.e. a network of geographically discrete colonies, which are linked by the dispersal of individuals between the colonies to form a single large population.
- The regular cutting of regrowth on wayleaves provides suitable sheltered and open habitat, and their linear nature means that they can act as ideal corridors along which individuals can fly to neighbouring colonies
Chequered Skipper Facts
The Chequered Skipper, so called because of the golden chequered pattern on its wings, is the only skipper butterfly in northwest Scotland.
In warm weather the adults are extremely active and fly with a swift, darting, almost moth-like gait that is difficult to follow as they 'skip' just above the vegetation.
Chequered Skipper butterflies need sheltered open rides in sunny damp woodlands where lush Purple Moor grass grows. Wayleaves often provide ideal habitat but must be kept scrub and bracken free. Grazing is not essential as long as the site remains open.
