Between 1970 and 1984, despite hundreds of sites being examined, the Essex Skipper was confined to only 26 kilometre squares out of a total of over 2,900. By 2010-14 it had expanded to 276 squares and had spread first into North and East Dorset, later into South Dorset and finally only the far west of Dorset remained without records. The mechanism for its speedy expansion from Essex and the South East to Dorset is thought to have been hastened by the passage of hay lorries from East Anglia which unintentionally spread the eggs along the grass verges of the main roads.

The difficulty of telling the Essex apart from the Small Skipper means that it is undoubtedly under recorded in some areas.

Notes

Size: small.

The most reliable way to tell an Essex Skipper from a Small Skipper is by the black tips to its antennae: they must show a clear cut offs which are visible from the underside too. If the antennae are greyish, brown or patchy black, they are not Essex.

A less reliable feature is that with Essex Skippers the underside tips of the upper wings are usually orange like the rest of the wing. Small Skipper wing tips change to a muddy yellow which matches the colour of their hind wing underside.

The scent brand (the black slash) on the upper forewing of the male Essex Skipper is short, straight & parallel with the wing edge. The Small Skipper scent brand is long, thick, slightly curved and not parallel to the edge of the wing.
