Large
White
Pieris brassicae
There are usually 2 broods of this species in Britain, emerging in
May and August. The resident population is supplemented by
migrants from Europe, which often arrive in large numbers during
the spring and summer. The adult butterflies are highly
mobile, covering vast distances and exploring all available
habitats in search of their larval foodplants and nectar sources.
In spring they will nectar at dandelion, bugle and wood spurge. In
summer they strongly favour thistles, knapweeds, marjoram and
Buddleia.

Ringlet
Aphantopus
hyperantus
The Ringlet occurs throughout England, Wales, southern Scotland
and Ireland. It
breeds mainly in
woodlands, where it inhabits rides and glades where the grasses grow tall and
lush. It also occurs in small numbers on scrubby
grassland, where it occupies damp hollows which have escaped grazing.
Ringlets are noted for their characteristic flip-flop
flight over short distances, and rarely cover more than a few
metres at a time. They are active in warm, but overcast
conditions, and will fly even during light rain.

Small
Copper
Lycaena phlaeas
The Small Copper
is found in many habitats including calcareous grassland, heaths, sand dunes, cliff tops, railway
embankments, old quarries, sunny woodland rides, meadows and almost anywhere
else where the larval foodplants grow. The butterflies tend to be
localised within each habitat, breeding in sheltered hollows, or at the bottom
of sunny slopes. There are
normally 2 or 3 broods per year, depending on locality and weather
conditions.

Brown
Argus
Aricia agestis
In England this species
breeds mainly on calcareous grasslands, where the larval foodplant
common rockrose grows amongst fine grasses. Many sites are on south facing
slopes, and characterised by an abundance of ant-hills on which the
foodplant grows.
Both sexes nectar at a wide
variety of low growing flowers, including daisy,
bird's foot trefoil, dandelion, rockrose and marjoram. In late
afternoon they roost communally on grass-heads.

Adonis
Blue
Lysandra bellargus
The Adonis Blue,
like most other "blues" is sexually dimorphic - only the males
have the beautiful electric blue colouration. Females
by comparison are dull chocolate brown, with a dusting of deep
blue scales across the basal and median areas of the wings. The
extent of the blue dusting varies considerably between individuals
of the same population. All females also have a dark discal spot
on the forewings, and a row of orange sub-marginal lunules on the
hindwings.

Small
Skipper
Thymelicus
sylvestris
S mall
Skippers
are active in sunshine, and have a rapid buzzing flight,
"skipping" from flower to flower. Favoured nectar sources include
clovers, bird's foot trefoil, vetches, thistles, and ox-eye
daisies.
In weak or hazy sunshine
they often sit on grass blades or stems, basking with their wings
held in the typical Hesperiine position.
The adults emerge in July, and lay their eggs in groups of 4 or
5, placed in a row within the sheath of stems of grass, nearly
always Yorkshire fog.

Essex
Skipper
Thymelicus lineola
In Britain this species was
formerly restricted to Essex and Suffolk, but in the latter part of the 20th
century spread rapidly across most of the southern counties of England, via
motorway verges. Dispersal was further aided when eggs were inadvertently
transported in hay bales.
It
is very easy to confuse this species with the Small Skipper
Thymelicus sylvestris,
with which it often shares it's habitats. The easiest way to tell the species
apart is to examine the underside tips of the antennae, which are
orange or reddish in
sylvestris, but jet black in
lineola.

Green-veined White
Pieris napi
When
seen in flight this species can be confused with the Small White, but while the
Green-veined White has a lazy flight, usually fairly close to the ground, the
Small White has a stronger and more directional flight pattern, and looks
brighter.
The
Green-veined White is found throughout Britain, except on the Shetland Isles. It
occurs in damp sunny situations - woodland rides, riverbanks, ditches bordering
hedgerows, and wet meadows.
|
 |
Small
Blue
Cupido minimus
The Small Blue is the smallest butterfly found in the UK, and one of the
smallest in Europe. The
butterflies are usually found in small groups of a dozen or so.
Males spend most of their time basking with wings half-open,
on grass blades or other low foliage,
where they await passing females.
The adults emerge in late May and there is usually a partial second brood in August. They lay their
pale greyish-blue eggs singly on the flowers of kidney vetch.

Meadow
Brown
Maniola jurtina
The Meadow
Brown is one of the commonest and most widespread species in
Britain.
It
is adapted to a wide range of grassy habitats, being found in the greatest
numbers on ungrazed calcareous grasslands, woodland glades and rides, damp
heathlands, hay meadows and along hedgerows. In these habitats populations often
run into several hundreds or even thousands.
This is a single brooded species with a
protracted emergence beginning in early June and extending into
early September.

Swallowtail
Papilio machaon
In Britain the Swallowtail is found only on
the fens and broads of north-east Norfolk, where the butterflies emerge in late May and early June.
They lay their large brown globular eggs, singly, on the fine
leaves of milk parsley.
On warm sunny days Swallowtails
patrol back and forth along a regular route, fluttering their
wings constantly as they nectar at the pink flowers of angelica,
knapweeds, marsh thistles, red campion, ragged robin and valerian.
This fluttering behaviour is typical of all Papilioninae, wherever
they occur in the world.

Glanville
Fritillary
Melitaea cinxia
Glanville Fritillaries fly rapidly just above the ground, settling
to bask periodically on low foliage or bare ground.
Males patrol the breeding sites, intercepting all other Glanville Fritillaries of either sex. If a
male meets a female that has already mated, she settles amongst
low grasses, flutters her wings rapidly, and slightly raises her
abdomen as a rejection signal. When a male encounters a virgin female copulation
takes place almost immediately without any preliminary courtship,
and the pair remain copulated overnight.
|
 |
Heath
Fritillary
Mellicta athalia
This species is at the edge of it's range
in Britain, and is restricted to a
very limited range of habitats.
In
Kent and Essex the butterflies are confined to a complex of small to medium
sized woodlands which are managed as sweet chestnut coppice, with a fairly open
canopy of oaks. Here the butterflies breed in small temporary clearings, where
the parasitic herb cow wheat ( larval foodplant ) grows in
profusion. The sites on Exmoor are entirely different in nature -
sheltered hillsides and lightly wooded valley bottoms where cow
wheat grows amidst bracken or heather.

Chequered
Skipper
Carterocephalus
palaemon
By the
mid-1970's this species had become extinct in England, but it is still a fairly
common butterfly in the western Highlands of Scotland, where it was first
discovered in 1942. It
breeds at warm, sheltered and damp sites where the larval foodplant, purple moor grass,
grows in lightly wooded areas. These include sunny glades in oak or birch woodland, lightly wooded
gullies on hillsides and mountains, young conifer plantations and scrubby areas
on the northern and eastern shores of Lochs. The butterflies emerge in May, and
nectar at bugle, dandelion and bluebells.

Almost every British and European species of butterfly is declining rapidly in
numbers, due in most cases to loss or degradation of habitats.
You
can help to reverse the decline by supporting conservation organisations which
purchase and manage habitats as nature reserves, and which lobby government at
local, national and international levels, often very successfully, to bring
about changes in farming, forestry and urban development policies.
Please contact the conservation organisations for
advice on how you can help protect British and European butterflies and their
habitats. You may be able to offer practical help e.g. by monitoring butterfly
populations or helping to manage nature reserves. Donations to these
organisations enable them to employ ecologists and biologists. Even if you are
unable to provide such help, merely having your name on the membership list can
be a powerful tool for conservation organisations wishing to demonstrate the
levels of support they have for their policies.
