The Northern Brown Argus is a nationally scarce species and one of Scotland’s most threatened butterflies.
The butterfly mostly inhabits flower-rich grasslands either at the coast or in the uplands. The presence of Common Rock-rose is essential as this is the sole foodplant of the butterfly’s caterpillar. Sadly species-rich grasslands are under threat, having declined nationwide by over 97% in the last century.
Surveys are best undertaken between late-June and the end of July. Surveys can take place in dull weather as presence of the butterfly is most easily confirmed by searching for the conspicuous eggs.
The online training workshop will be held via Zoom on Tuesday 13th June at 7pm. A recording of the workshop will be made available for anyone who cannot attend. Please sign up to the workshop here
