Brachycera (Diptera) records from Britain and Ireland to 1990
This dataset is held at the BRC and was used for the 1991 publication: 'Provisional Atlas of the Larger Brachycera (Diptera) of Britain and Ireland'. The dataset covers robberflies, bee flies, soldierflies, horseflies and their allies. Data were collected by volunteer recorders and compiled by the Larger Brachycera Recording Scheme, which began in 1976.
The dataset contains records from throughout the British Isles. Recording is strongest in the SE of England, lighter in northern England and Wales and there are very few Scottish and Irish records.
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.
Data were checked as far as possible by the Scheme organiser at the time but this was not possible for all records.
Standard field methods were used and data were recorded on BRC 'RA34' record cards. Conversion to electronic format occurred at the BRC.
