Description
The Essex Skipper and Small Skipper are almost identical in appearance which often makes identification in the field extremely difficult even for the experienced lepidopterist as they are often found living in the same habitats and on the wing at similar times. This similarity explains why it was not until 1888 that the Essex Skipper was recognised as a separate species.

One key difference between the Essex Skipper and the
Small Skipper is that the Essex Skipper has a distinctive glossy black tip to its antennae while the Small Skipper has dull brown/orange tips. Small Skippers are also slightly more orange in appearance while the Essex Skipper tends to be more of a dull brown/tan colour.

The adult butterflies spend much of their time basking or resting on grass stems in typical 'golden skipper' style and can be seen from early June until late August although numbers have decreased dramatically by mid August.

The eggs of the Essex Skipper do not hatch until the following spring although the larvae are fully formed within the egg shell. They feed within a shelter constructed by spinning the edges of grass blades together with fine silk threads to make a narrow feeding tube which also protects the caterpillar from predators. They will however emerge and feed in the open at night and as they become larger tend to spend more time feeding in the open... even during the day. The caterpillar is green in colour with a pale yellow line running along the length of each side of its body and a dark line along its back. The head is brown.

Pupation takes place during early summer at the base of the larval food plant within a silken cocoon spun between grass blades. The pupae are pale green in colour. The adult Essex Skipper butterflies tend to emerge about three weeks after pupation with peak numbers seen during July. By September very few adults are on the wing.
Habitat
The Essex Skipper is found in tall dry grasslands in open sunny locations. It is commonly found on disused railways and roadside verges where the larval foodplant grows.
Distribution
The Essex Skipper can be found throughout South-East England as far west as Somerset/Dorset and as far north as South Lincolnshire and the Midlands. Its range has extended dramatically over the last 10 years.

Other notes
Very difficult to distinguish from the Small Skipper in the field although experience of behavior and slight variation in wing shape and colour help to separate the two.
