Species Profile
Amber List (declining in some regions due to habitat loss and agricultural intensification)
- Lifespan
- 2–3 weeks as an adult butterfly; larvae develop over several months
- Size & Weight
- Wingspan 32–38 mm
- Habitat
- Open grasslands, heathland, meadows, and rough ground with sparse vegetation, particularly where fine grasses are abundant.
- UK Distribution
- Widespread throughout England, Wales, and southern Scotland; resident year-round with multiple generations per year, though absent from the far north.
- Diet
- Adults feed on nectar from wildflowers and sometimes aphid honeydew; caterpillars feed on fine grasses including Sheep's Fescue and Meadow Grass.
- Predators
- Spiders, robber flies, and bird species such as flycatchers and warblers.
- Mating Season
- May to September, with overlapping generations
- Breeding
- Three to four broods per year in the UK; females lay eggs singly on grass blades; caterpillar stage lasts 3–4 weeks; pupation occurs on or near the food plant.
- Behaviour
- Small Heath butterflies are weak, low fliers that rarely venture far from their breeding habitat. Males perch on grass stems and patrol in sunny weather, pursuing females with a characteristic bobbing flight. They rest with wings folded and are well-camouflaged when stationary.
- •The eyespots on the underside of the hindwings are thought to deflect predator attacks away from vital body parts.
- •Small Heath populations can fluctuate dramatically year to year depending on spring weather conditions.
- •They are among the earliest butterflies to emerge in spring, sometimes appearing in March.
- •Males exhibit territorial behaviour, returning repeatedly to favoured basking spots on warm days.
- •The species has a characteristic jerky, bouncing flight that distinguishes it from other small brown butterflies.
