Description
The Small Skipper and Essex Skipper are almost identical in appearance which often makes identification in the field extremely difficult as they are often found living in the same habitats and on the wing at similar times.

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

The adult butterflies spend much of their time basking or resting on grass stems in typical 'golden skipper' style.

The eggs of the Small Skipper hatch in late summer (unlike those of the
Essex Skipper which do not hatch until the following spring) and the tiny young caterpillars hibernate within the sheath of grass where the eggs were laid. The following spring 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 emerge and feed in the open at night. As the larvae become larger, they tend to spend more time feeding in the open. The caterpillar is yellowish-green in colour with a pale yellow line running along the length of each side of its body. The head is dark green.

Pupation takes place during May and June 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 Small Skipper butterflies tend to emerge during early June with peak numbers seen during July. By September very few adults are on the wing.
Habitat
Colonies of the Small Skipper can be found where grasses are allowed to grow tall and lush. Habitats include disused railway lines unimproved rough grassland and verges. Colonies can occur on very small patches of suitable habitat such as a roadside and railway verges.
Distribution
Found throughout England and Wales as far north as Tyne and Wear the Small Skipper is however absent from North-West Wales Lancashire and Cumbria. Its distribution has expanded northwards in recent years.

Other notes
Very difficult to distinguish from the Essex Skipper in the field unless you can get a good view of the underside of the antenna. Experience and knowledge of behavior in the field slight variation in wing shape and colour help to separate the Small Skipper from the Essex Skipper.
