Also known as the woodman's friend, the delightful orange-brown Pearl Bordered Fritillary was once a common butterfly in Scotland’s woodlands. They are now considered nationally scarce in Britain due to a rapid decline, and Scotland is their main stronghold.

In 2011 the Pearl Bordered Fritillary was positively identified at Loch Katrine for the first time in 25 years. The Great Trossachs Forest is providing vital habitat for the butterflies, which favour south facing slopes on the edge of woodlands, with abundant wildflowers especially dog violets and bugles.

This butterfly is very similar in appearance to the Small Pearl Bordered Fritillary, with the main difference between them being a string of 'pearls' on the Pearl Bordered Fritillary.
