Overview

The Small Skipper arrived on the Sefton Coast in the mid-1990s — a rapid northward colonisation that coincided with warming summers. In Merseyside it was previously unknown north of the Wirral. Now it's firmly established and common on the tall rough grassland of the dune system. The burnt-orange wings held at the distinctive 'jet' angle (forewings raised, hindwings flat) are the classic skipper look. They dash between grass flowers with rapid, buzzing flight.

Frequently Asked Questions

How did Small Skippers reach the Sefton Coast?

Small Skippers were unknown north of the Mersey until the mid-1980s. Their rapid northward spread is attributed to a sequence of warm summers that allowed the species to colonise suitable habitat beyond its previous range limit. First recorded at Altcar Rifle Range in 1996, they spread rapidly across the Sefton Coast dunes over the following years.
