The Status of the Caddis Adicella filicornis in Wales (2016)
A survey for the Endangered caddis Adicella filicornis (Trichoptera) in 2016 found pupal cases at all four Welsh sites with modern records, and a single adult. Populations at Coed Dol-goch, Halton Wood, Prisk Wood and Wilderness Wood appear to be small and the habitat used by the caddis - very small permanent streams on quite steep slopes close to their origin from groundwater springs - is also highly localised and very fragile. Only Coed Dol-goch supports a reasonable area of habitat with several stations being occupied. None of the sites has any statutory protection, although Prisk Wood is owned by the Gwent Wildlife Trust and Coed Dol-goch is a community woodland. Consideration should be given to notifying one, if not all, sites as Site of Special Scientific Interest (SSSI) for Adicella filicornis. Prisk Wood and Wilderness Wood also support the only Welsh populations of the rare cranefly Ellipteroides alboscutellatus, a species associated with tufa-depositing seepages. Further surveys for Adicella filicornis at all four occupied sites are required to determine its status and distribution and to identify threats to its habitat.
