History
Sir Arthur Duncan caught two specimens on Kirkconnell Flow during early July 1977 and another the following July, all at National Museums Scotland.
 
"On 9th July 1995, while walking through dense Bilberry Vaccinium myrtillus bushes on the western edge of Kirkconnell Flow NNR, we disturbed a number of pugs which we tentatively identified as the Bilberry Pug. The identification was later confirmed by Martin Honey of the Natural History Museum, London." (The Entomologist's Record and Journal of Variation 109: 108)
 
Further specimens occurred during July 1996, with another on 22nd June 1997. Five years elapsed before another was caught in a Heath trap on 27th July 2002. Two more were found in 2014, one at Kirkconnell Flow NNR on 29th June and the first for Dumfriesshire at Kelhead Flow on 23rd July.
