Species Profile
Green List (stable and secure in the UK)
- Lifespan
- 2–3 weeks as an adult butterfly; larvae overwinter and develop over several months
- Size & Weight
- Wingspan 26–30 mm
- Habitat
- Open, sunny grassland, woodland edges, verges, and rough ground where its larval food plant occurs.
- UK Distribution
- Widespread across southern England and increasingly northward; resident, with populations that have expanded northwards over recent decades, now found as far north as the Midlands and beyond.
- Diet
- Adults feed on nectar from wildflowers; larvae feed exclusively on Yorkshire fog grass (Holcus lanatus).
- Predators
- Small birds, spiders, and parasitoid wasps; vulnerable to ground-dwelling predators as pupae.
- Mating Season
- July to September
- Breeding
- Single brood per year; females lay eggs on Yorkshire fog grass in late summer; larvae overwinter in a diapause stage and pupate in spring, with adults emerging in mid-summer.
- Behaviour
- Males are highly territorial, basking with wings closed and making rapid patrol flights along grassland margins. They are enthusiastic fliers but remain low and close to the ground. Adults have a distinctive jerky, erratic flight pattern.
- •The Essex Skipper was first recorded in Britain in 1889 near Colchester, Essex, and is believed to have arrived from continental Europe.
- •Unlike the similar Small Skipper, the Essex Skipper has black underside antennae tips, while the Small Skipper's are orange.
- •Its rapid northward range expansion in recent decades is thought to be linked to climate warming.
- •Larvae are nocturnal feeders and construct shelter by rolling leaves on their grass food plant.
- •The species is now more common and widespread in the UK than it was 30 years ago, making it one of our expanding butterfly species.
