Buglife is delighted by the recent rediscovery of a species of caddisfly previously believed to be extinct across the UK. Once found in the fens of East Anglia, Limnephilus pati was presumed extinct in the UK in 2016 with no British records for over 100 years. Elsewhere, there are only 16 historical sites scattered across Denmark, France, Germany, Ireland, the Isle of Man and Poland.
In July last year, against all odds, a male was attracted to a light-trap being run by Robin Sutton on South Uist in the Outer Hebrides. Photos of the specimen were sent for identification and the exciting result was the rediscovery of Limnephilus pati.
South Uist is rich in habitats for caddisflies, with numerous small lochans, clear, low nutrient streams, and extensive machair habitats. Over the years Robin has attracted 23 species of caddisfly to his light trap but by far the most exciting find is Limnephilus pati.
