Butterfly guide: how to identify UK butterfly species
Butterflies are an integral part of spring and summer, but do you know which species is flitting before you?
What butterfly have I seen?
The UK has 59 different butterfly species, each playing an important role in pollination. Whether you’ve spotted a deep-red peacock butterfly or the well-disguised brimstone, here are a few species found along our canals.
Peacock butterfly
Bright red wings with black markings, peacock butterflies are one of our most popular species. So-called for the blue spots on the forewings and hindwings, resembling the 'eyes' of peacock feathers, which ward off predators.
As caterpillars, they're jet black with small white spots.
Peacock butterflies are attracted to ivy.
Red admiral butterfly
These butterflies are large, strong fliers with red stripes on the wings and white spots towards the tips of the forewings.
As caterpillars, red admiral butterflies are black and spiny with fine hairs and a yellow stripe along its underside.
The red admiral was once called the 'red admirable'.
Small tortoiseshell butterfly
Small tortoiseshell butterflies have red-orange wings with black and yellow markings and a ring of blue spots on the tips. These butterflies are seen in the late summer and throughout September.
The pretty small tortoiseshell butterfly can be found anywhere from city centres to mountain tops!
Common blue butterfly
Males are bright blue with brown lining around the wingtips and a white fringe. Females are a light brown colour, with blue dusting close to the body and a white fringe.
The common blue is the most widespread blue butterfly in England and Wales.
Large white butterfly
Large white butterflies have brilliant white wings with one or two black spots. They have a wingspan of 5.8-6.3cm and are, as the name suggests, larger than other white butterflies.
These butterflies are sometimes called 'cabbage whites' as they eat cabbage leaves as caterpillars.
Brimstone butterfly
Masters of disguise, brimstone butterflies are medium sized with wings that blend in with their surroundings. Their wingspan can grow up to 6cm. Females have veiny, pale green, leaf-shaped wings with orange spots. Males are similar but with a stronger yellow-green colouring.
Brimstone butterflies are one of the first butterflies to emerge from hibernation. You might see them on early warm spring days. They live in damp woodlands and mature hedgerows.
As caterpillars, brimstones are pale green. They're similarly camouflaged against the green of the leaves they eat.
Brimstone butterflies are often one of the first species on the wing in spring.
Meadow brown butterflies are brown with washed-out orange markings. They're most identifiable by two eyespots on their forewings. These spots each have one white pupil.
Meadow brown butterflies are medium-sized with a 4-6cm wingspan. They're a common sighting in grassland. Unlike other butterflies, the meadow brown still flies in duller weather and is on the wing from June to September.
Males are much more active than females, who spend more of their time hiding in the grass.
Meadow brown butterflies are often seen flying in large groups over grass and flowers.
Speckled wood butterfly
Speckled wood butterflies are a warm brown colour with cream spots. They have one eyespot on the forewings and three on the hindwings. They have a 4.6-5.6cm wingspan.
Active between March and October, you might spot speckled wood in grasslands, hedgerows, woodlands, or gardens.
As caterpillars, speckled woods are bright green with dark green and yellow stripes.
The speckled wood prefers shaded and dappled sunlight to bright sunny spots.
Gatekeeper butterfly
Gatekeeper butterflies are rigorous patrollers of hedges and woodland rides. They're brown and orange with black spots on their wings containing two smaller white dots. Males are slightly smaller, with dark markings on the forewings.
Gatekeepers are widespread across England and Wales, thriving in scrubland and along hedgerows.
As caterpillars, they're either light brown or green.
Gatekeepers are so named for their patrol of hedges, woodland rides, and field edges.
