A hidden population of one of England\u2019s rarest moths has been found at a site where it has not been seen for 70 years \u2013 by a conservationist who has spent his life searching for them.<\/p>\n
Dr Dave Wainwright, of Butterfly Conservation, has described his overwhelming sense of relief at having tracked down a second site in England for the dark bordered beauty moth, at the National Trust\u2019s Wallington Estate in Northumberland.<\/p>\n
For decades before the discovery, the only site where the custard and chocolate coloured day-flying moth was found in England was at Strensall Common in North Yorkshire.<\/p>\n
But that population has been declining rapidly, with numbers dwindling from hundreds of the moths 20 years ago, to barely reaching double figures last year, Butterfly Conservation said.<\/p>\n

The site is being affected by climate change, making drought and wildfire more common \u2013 with a blaze that tore through part of the nature reserve, managed by Yorkshire Wildlife Trust and the Ministry of Defence, last year putting the moth in an even more perilous situation.<\/p>\n
The discovery of a second population in England gives new hope for the rare species, conservationists said \u2013 not least because the landscape they were found in is different habitat to the Yorkshire site, opening up the possibility they may be found in other places.<\/p>\n
The moth was once widespread across northern England and Scotland, but has seen serious declines as a result of habitat loss and is now restricted to two small areas on Deeside and Speyside in Scotland, as well as the \u2013 now two \u2013 sites in England.<\/p>\n
A key challenge for conserving the moths is their caterpillars only eat two plants, aspen and creeping willow.<\/p>\n
Dr Wainwright has been searching for new English colonies since he started work at Butterfly Conservation in 2004 \u2013 at work and in his own time<\/p>\n
Back in 2004, he visited the Wallington Estate, where the dark bordered beauty had previously been found, but not since 1952, but he failed to track down any moths.<\/p>\n

This time, however, the habitat had been transformed by the National Trust and its tenant farmer through nature-friendly farming, reducing livestock grazing in key areas and restoring peatland.<\/p>\n
\u201cI looked at that site in 2004 and it was quite heavily grazed and wasn\u2019t in the right condition for dark bordered beauty,\u201d Dr Wainwright said.<\/p>\n
\u201cThis time the site looked a hell of a lot better \u2013 really lush vegetation with lots of wildflowers.<\/p>\n
\u201cIt only took 10 minutes to find the first one, then we all started picking them up quite regularly. I think the others were excited, but perhaps not as excited as I was.\u201d<\/p>\n
He added: \u201cI was hopeful \u2013 I\u2019m always hopeful \u2013 but I definitely didn\u2019t expect it because I\u2019ve been to so many sites to look for this species over the years, so my heart and my head were in two different places.\u201d<\/p>\n
When they found one within minutes it was, he said, \u201cone of the highlights of my career\u201d.<\/p>\n
\u201cOverwhelmingly it was just a feeling of relief that we weren\u2019t just fighting the fight at one site any more,\u201d he added.<\/p>\n
Emily Johnson, ranger at Wallington, said: \u201cWe couldn\u2019t be more excited to find that Wallington is a stronghold for such a rare species.<\/p>\n
\u201cWe have been working hard to manage the land better for nature, and it seems to be paying off.\u201d<\/p>\n
The team behind the \u201cWilder Wallington\u201d nature recovery project hope to expand potential habitat for the rare moth, with advice from Butterfly Conservation.<\/p>\n
Now it feels like there could be other colonies out there waiting to be discovered which would be brilliant<\/p>\n

Butterfly Conservation is also working with Yorkshire Wildlife Trust to manage habitat at Strensall Common and is planning to trial a captive breeding programme, but the charity says the moth is clearly struggling at the site.<\/p>\n
Dr Wainwright said the discovery at Wallington \u2013 a different environment to Strensall on which conservationists had based their idea of \u201cgood habitat\u201d for the moths \u2013 opened up a new front in their knowledge of the species.<\/p>\n
He said other sites came to mind that experts would not have thought of as prime dark bordered beauty habitat before.<\/p>\n
\u201cThe thing that\u2019s kept me going all these years is I always felt there was a chance of finding Dark Bordered Beauty on the Northumberland\/Cumbria border \u2013 now it feels like there could be other colonies out there waiting to be discovered which would be brilliant,\u201d he added.<\/p>\n","protected":false},"excerpt":{"rendered":"A hidden population of one of England\u2019s rarest moths has been found at a site where it has…\n","protected":false},"author":2,"featured_media":737326,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[90,56,54,55,4407],"class_list":["post-737325","post","type-post","status-publish","format-standard","has-post-thumbnail","category-wildlife","tag-science","tag-uk","tag-united-kingdom","tag-unitedkingdom","tag-wildlife"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/737325","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=737325"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/737325\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/737326"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=737325"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=737325"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=737325"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
