Bringing to life spectacles of natural wonder on our doorstep
Butterflies boast have some of the most vivid colours of any of the UK’s animals.
The colouring of a butterfly’s scales can also result from a pigment which results in spectacular reds, yellows, whites and browns. It can also result from effects created by the way light hits the butterfly’s wings in the case of blues, greens and iridescent colours. The tiny ridges on the butterfly’s scales refract the light in a similar way to a prism creating a rainbow from sunlight.
There are 56 species of butterfly in Britain and Ireland but many are under threat from environmental change and the destruction of their habitats.
The British Swallowtail is the biggest native butterfly in the UK with distinctive markings including pale yellow wings with black veins and blue edges. Its patterns are made up of a mass of tiny scales, which overlap like tiles on a roof. Look out for its distinctive red spot and forked tail.
The Common Blue is the most widely distributed blue butterfly in Britain, and is found mainly in grasslands. The male has blue wings with a white fringe and brownish border whilst the female is a brown colour with a blueish body and patterned border.
The Silver Studded Blue butterfly is similar to the Common Blue, but is rarer and bluer – it's found largely on heathland. The male is silvery-blue whilst the females are brown with a distinctive metallic spot on their wing.
The Purple Emperor is another stunner - the male has a purple sheen. Its larvae hibernate on willow buds or in forked tree branches and then pupate hanging from leaves.
Butterflies don’t live very long - on average between 20-40 days - although some can live for up to six months.

Tips for viewing this species:
Butterflies like sheltered grasslands, meadows, and heathland but can also be found in coastal areas, woodland clearings, parks and gardens.
It’s rare to get mass gatherings of butterflies in the UK mainly because of habitat loss. The Great Orme in North Wales is one of the last places in the UK where you can see a rare butterfly spectacle. Sometimes there are half a million butterflies in an area of just 60 hectares. There have been local reports of clouds of butterflies and people barricading themselves in their houses to hide from tens of thousands of caterpillars!
The Great Orme is a good place for butterflies because the grassland isn’t heavily grazed or cut. The south west facing slopes are best as they are sheltered and sunny.
Butterflies roost together because there’s a shortage of suitable sites. Attracting a mate is a very competitive business – the males show off by holding onto the best perches to impress the females.
Adult butterflies feed on nectar from any available flower but the caterpillars of each species have their own food plant. The Silver Studded Blues will only lay their eggs on Birds Foot Trefoil, Common Rockrose and sometimes wild Thyme which the caterpillars eat when they emerge.
The caterpillars turn into a chrysalis and then into butterflies with a little help from their friends - ants! The caterpillars generate pheromones to attract ants which protect them from parasites until the adult butterfly is ready to emerge. The caterpillars produce a sugary substance from a honey gland which the ants can't resist!.
Seventeen species of bats can be found in Britain from two main families - find out about their roosting habits.
