Conditions were n’t looking too hopeful for the white - missive hairstreak butterfly , an knotty butterfly that ’s native to the UK . Threatened by habitat departure , the butterfly ’s number have dwindled by 96 percent since the 1970s , and the insect has n’t even been blemish in Scotland since 1884 . So you may imagine the surprisal lepidopterists feel when a white - letter of the alphabet hairstreak was visualise feeding in a field in Berwickshire , Scotland originally in August , grant toThe Guardian .
A humans named Iain Cowe noticed the butterfly stroke and managed to capture it on camera . “ It is not every day that something as special as this is establish when out and about on a even butterfly raid , ” Cowesaid in a statementprovided by the UK ’s Butterfly Conservation . “ It was a very ragged and raddled someone ground feeding on ragwort in the grassy sharpness of an arable field . ”
Thewhite - letter hairstreakis a modest chocolate-brown butterfly with a white “ W”-shaped streak on the underside of its wing and a pocket-size orange place on its hindwings . It ’s not well sight , as it tends to spend most of its life prey and engender in crown .
The butterfly stroke ’s preferred habitat is the elmwood tree , but an eruption of Dutch elm disease — first notice the 1970s — forced the blank - letter hairstreak butterfly to discover novel home and food sources as million of Britain ’s elm tree trees croak . The threatened coinage has slowly spread north , and experts are now promising that Scotland could be a proficient home for the insect . ( Dutch elm disease does survive in Scotland , but the nation also has a good amount of disease - repellent Wych elm . )
If a breeding colony is confirmed , the white - letter hairstreak will happen Scotland ’s number of butterfly stroke metal money that exist and breed in the country up to 34 . “ We do n’t have many butterfly stroke species in Scotland so one more is very nice to have , ” Paul Kirkland , director of Butterfly Conservation Scotland , say in a command .
Prior to 1884 , the only confirm sighting of a white - letter hairstreak in Scotland was in 1859 . However , the insect ’s newfound presence in Scotland comes at a price : The UK ’s butterfly are moving north due to climate change , and the white - letter of the alphabet hairstreak butterfly ’s reaching is “ almost certainly due to the thawing clime , ” Kirkland said .
