Caddisfly (Trichoptera) records from Britain and Ireland to 2012
This Trichoptera dataset originates from the National Trichoptera (Caddisfly) Recording Scheme. The survey data comes in four categories ranked in terms of contribution: volunteer recorders; statutory monitoring bodies, especially the Environment Agency; major national, and many local, entomological journals; museum collections. Recording is still continuing and annual up-dates are an aspiration. Many local check-lists are being prepared for electronic and paper publication. The data set contains records from a variety of well-circulated sources e.g the literature, that are considered incorrect. These are included, with an explanation, to flag-up that they have been assessed to assist researchers who encounter them elsewhere.
Recording for this dataset is reasonable in England and Wales but more patchy in Scotland. Ireland both north and south are covered by a recording scheme operated by Jim O'Connor of the National Museums of Ireland. The Isle of Man but not the Channel Isles are also covered. The two major national recording schemes plan a joint atlas for the British Isles.
Records are collated in order to add to knowledge of this group, including distribution, population trends, autecology and phenology. In addition, the scheme works with all contributing recorders to raise the profile of the species group and its conservation. Sharing the data via NBN helps achieve these aims.
Records were validated and verified by Ian Wallace, sometimes from voucher specimens.
