The White Admiral is a woodland species and a delight to behold as it literally glides along forest rides, flying from tree to forest floor and back up with only a few effortless wing beats. For this reason, some of its closest relatives on the continent are known as "gliders". When settled, the adults are unmistakable, with their black uppersides intersected by prominent white bars. The undersides of this butterfly are, however, in complete contrast to the black-and-white uppersides, and are surely one of the most beautiful of all species found in the British Isles.
The butterfly is found in central and southern England, and the eastern counties of Wales. It is not found in Scotland or Ireland. The distribution of this species in the early 1900s had declined to the point that it was restricted to southern England. However, there seems to have been a reversal of fortunes, with the butterfly reaching its formal distribution that extends as far north as Lincolnshire. One explanation is that global warming has allowed the species to thrive at sites that had become too cool. Another is that the cessation of coppicing, that has been detrimental to so many woodland butterflies, has benefited this species which requires Honeysuckle growing in shady woodland for the successful development of its larvae.
Adults emerge in the second half of June and peak in the first part of July. There is usually one brood each year but, in some years, there may be a partial second brood in late summer. 
This is a woodland butterfly and is found in deciduous woods throughout its distribution. However, it can also be found in conifer plantations, so long as Honeysuckle is available in suitable locations.
The primary larval foodplant is Honeysuckle (Lonicera periclymenum).
Adults feed primarily on Honeydew / Sap. Betony (Stachys officinalis), Bramble (Rubus fruticosus agg.), Hogweed / Angelica (Umbelliferae), Privet (Ligustrum vulgare) and Thistles (Cirsium spp. and Carduus spp.) are also used.
Males and females are similar in appearance, although females are slightly browner and larger, and have more-rounded wings. The adults feed from honeydew and are particularly partial to Bramble blossom. It is not uncommon, on good sites, to see several White Admiral all feeding from the same Bramble patch. A downside of this, however, is that their wings can get tatty very quickly, as they move around Bramble blossom, probing for nectar. The adults will also feed on salts and minerals from moist earth and animal droppings. The behaviour of the female when egg-laying is in complete contrast to the normal soaring flights, making her easy to spot. The female flits low in undergrowth or through shaded woodland, stopping every now and again on the foodplant to lay a single egg. The female selects Honeysuckle that is in partial shade, often at the edge of a woodland ride or in lightly-shaded woodland. She also selects leaves on straggly pieces of isolated plant, rather than the lushest leaves that are often growing in full sun.
Description to be completed
Eggs are laid singly on the upperside of a leaf of the foodplant, close to the leaf edge. Most eggs are laid less than two metres from the ground. The egg is a curious shape, looking rather like a miniature golf ball covered in miniscule hairs. This stage lasts about a week.
On emerging from the egg, the light brown larva eats the shell before moving to the leaf tip to feed. Here is feeds on each side of the midrib on which it rests, leaving the midrib intact, producing characteristic feeding damage that is quite easy to spot. The larva initially decorates itself with faeces that it uses for camouflage, although this is abandoned after a week or so, after which the larva rests quite openly on the midrib. Toward the end of the summer after the second moult, the larva builds a winter retreat, known as a hibernaculum. This is constructed by securing a leaf to the twig with silk (so that the leaf remains attached to the foodplant even after it has died), removing the edges of the leaf, and then folding what remains of the leaf edges together, forming a compartment within which the larva overwinters. The larva emerges from the hibernaculum in the spring and, at the final moult, turns green in colour and starts to feed on the leaf edges rather than from the tip. The full-grown and exotic larva is a spectacular beast that would not look out of place in an Amazonian rainforest. It also has a curious habit of resting along the centre of a leaf with both front and back ends raised. There are 4 moults in total.
The pupa is typically formed upside down under a leaf or stem of the foodplant, secured by the cremaster. This stage is, again, a very curious shape, with two prominent horns on the head, and a curious protrusion at the back. This stage lasts 2 to 3 weeks.

This species has shown worrying declines in terms of distribution and population at monitored sites and is therefore a priority species for conservation efforts. Although numbers at existing sites have fallen, the expansion of the range of this species does appear to have continued in the last decade.
