Butterflies on Ashdown Forest SILVER-STUDDED BLUE Males blue with a dark border. Females brown with a row of red spots. Undersides brown-grey with black spots, a row of orange spots, and small greenish flecks on outer margin. Males are similar to Common Blue, which lacks greenish spots. This small butterfly is found mainly in heathland where the silvery- blue wings of the males provide a marvellous sight as they fly low over the heather. The females are brown and far less conspicuous but, like the male, have distinct metallic spots on the hindwing. In the late afternoon the adults often congregate to roost on sheltered bushes or grass tussocks. Butterfly Conservation priority: Medium UK BAP status: Priority Species GREEN HAIRSTREAK The Green Hairstreak holds its wings closed, except in flight, showing only the green underside with its faint white streak. The extent of this white marking is very variable; it is frequently reduced to a few white dots and may be almost absent. Males and females look similar and are most readily told apart by their behaviour: rival males may be seen in a spiralling flight close to shrubs, while the less conspicuous females are more often encountered while laying eggs. Although this is a widespread species, it often occurs in small colonies and has undergone local losses in several regions. Butterfly Conservation priority: Medium PURPLE EMPEROR This magnificent butterfly flies high in the tree-tops of well-wooded landscapes in central-southern England where it feeds on aphid honeydew and tree sap. The adults are extremely elusive and occur at low densities over large areas. The males occasionally descend to the ground, usually in mid-morning, where they probe for salts either from road surfaces or from animal dung. The Purple Emperor declined steadily during the twentieth century and is now restricted to some of the larger woods in southern England. There has been a recent slight re-expansion in some areas. Restricted to large woods in southern England where they spend much of their time in the treetops. Females resemble the White Admiral, but have an orange-ringed eyespot under the forewing.

In July it flies in areas of unimproved grassland and can occur in large numbers on southern downland. It shows a marked preference for purple flowers such as Wild Marjoram, Field Scabious, thistles, and knapweeds. Adults may be found roosting halfway down tall grass stems. Found in flowery grassland but may stray into gardens. This species is widespread in southern Britain and has expanded northwards and eastwards over the last twenty years, despite some losses within its range, with outlying populations in Yorkshire and SW Wales. Butterfly Conservation priority: Low COMMA The Comma is a fascinating butterfly. The scalloped edges and cryptic colouring of the wings conceal hibernating adults amongst dead leaves, while the larvae, flecked with brown and white markings, bear close resemblance to bird droppings. The most widely used foodplant is Common Nettle (Urtica dioica). Other species used include Hop (Humulus lupulus), elms (Ulmus spp.), currants (Ribes spp.), and Willows (Salix spp). Butterfly Conservation priority: Low SILVER-WASHED FRITILLARY The swooping flight of this large and graceful butterfly is one of the most beautiful sights to be found in woodland during high summer. A large fast flying butterfly, separated from other fritillaries by its pointed wings and silver streaks on the undersides which can be viewed as it stops to feed on flowers such as Bramble. Although the butterfly is seen mostly in sunny glades and rides, it actually breeds in the shadier parts of adjacent woodland. In southern England, a small proportion of females have wings that are bronze-green, known as the form valezina. Butterfly Conservation priority: Low (but a regional priority in several regions). https://butterfly-conservation.org/uk-butterflies/a-to-z Butterflies on Ashdown Forest PEACOCK The Peacock's spectacular pattern of eyespots evolved to startle or confuse predators, make it one of the most easily recognized and best- known species. It is from these wing markings that the butterfly gained its common name. Undersides of the wings are very dark and look like dead leaves. A fairly large butterfly and a strong flyer. Although a familiar visitor to garden buddleias in late summer, the Peacock's strong flight and nomadic instincts lead it to range widely through the countryside, often finding its preferred habitats in the shelter of woodland clearings, rides, and edges. Butterfly Conservation priority: Low RINGLET When newly emerged, the Ringlet has a velvety appearance and is almost black, with a white fringe to the wings. The small circles on the underwings, which give the butterfly its name, vary in number and size and maybe enlarged and elongated or reduced to small white spots; occasionally they lack the black ring. They are a dark brown butterfly and similar to male Meadow Brown. Bramble and Wild Privet flowers are favourite nectar sources, and adults continue to fly with a characteristic bobbing flight in dull, cloudy conditions when most other butterflies are inactive. Butterfly Conservation priority: Low LARGE WHITE A large, strong flying butterfly. The brilliant white wings have black tips to the forewings, extending down the wing edge. Females have two spots on the forewings, which is not present in males. The undersides are a creamy white with two spots. Butterfly Conservation priority: Low https://butterfly-conservation.org/uk-butterflies/a-to-z Butterflies on Ashdown Forest BRIMSTONE The Brimstone has spread in recent years, mainly in northern England. When this butterfly roosts among foliage, the angular shape and the strong veining of their wings closely resembles leaves. There is a view that the word 'butterfly' originates from the yellow colour of male Brimstones. The wings of the female are very pale green, almost white, males have yellow-green underwings and yellow upperwings. Butterfly Conservation priority: Low WHITE ADMIRAL This butterfly is widespread in southern England, extending just into Wales and northwards. It has white-banded black wings and a distinctive delicate flight, which has short periods of wing beats followed by long glides. It could be confused with the larger Purple Emperor. Adults are often found nectaring on Bramble flowers in rides and clearings. It is a fairly shade-tolerant butterfly, flying in dappled sunlight to lay eggs on Honeysuckle. The White Admiral occurs widely in southern Britain and has spread rapidly since the 1920s, after an earlier contraction. However, population monitoring has shown a dramatic decline in the last 20 years, for reasons that are as yet unclear. Butterfly Conservation priority: High UK BAP status: Priority Species SPECKLED WOOD Occurs in woodland, gardens and hedgerows. Butterflies often perch in sunny spots, spiralling into the air to chase each other. The aptly named Speckled Wood flies in partially shaded woodland with dappled sunlight. The male usually perches in a small pool of sunlight, from where it rises rapidly to intercept any intruder. Both sexes feed on honeydew in the treetops and are rarely seen feeding on flowers, except early and late in the year when aphid activity is low. The range of this butterfly contracted during the late nineteenth and early twentieth centuries but has spread back since the 1920s. It has continued to spread over the past two decades, recolonizing many areas in eastern and northern England and Scotland.

The brightly coloured males are conspicuous, but females are more secretive. The colour of the upperwings of females varies from almost completely brown in southern England to predominantly blue in western Ireland and Scotland, but the colour is variable within local populations with some striking examples. Unlike Adonis and Chalkhill Blues, the dark veins do not extend into white fringes of wing margins. It remains widespread but there have been local declines within its range. Butterfly Conservation priority: Low HOLLY BLUE Wings are bright blue. Females have black wing edges. Undersides pale blue with small black spots which distinguish them from Common Blue. The Holly Blue is easily identified in early spring, as it emerges well before other blue butterflies. It tends to fly high around bushes and trees, whereas other grassland blues usually stay near ground level. It is much the commonest blue found in parks and gardens where it congregates around Holly (in spring) and Ivy (in late summer). The Holly Blue is widespread but undergoes large fluctuations in numbers from year to year. It has expanded northwards in recent years and has colonised parts of midland and northern England. Butterfly Conservation priority: Low SMALL TORTOISESHELL Widespread throughout Britain and Ireland, commonly found in gardens. The Small Tortoiseshell is among the most well-known butterflies in Britain and Ireland. The striking and attractive patterning and its appearance at almost any time of the year in urban areas have made it a familiar species. It is one of the first butterflies to be seen in spring and in the autumn it often visits garden flowers in large numbers. The Small Tortoiseshell is one of our most widespread species and has shown little overall change in range. Butterfly Conservation priority: Low (but concern over recent decades) https://butterfly-conservation.org/uk-butterflies/a-to-z Butterflies on Ashdown Forest GATEKEEPER As its English names suggest, the Gatekeeper (also known as the Hedge Brown) is often encountered where clumps of flowers grow in gateways and along hedgerows and field edges.
