I caught a largish male Anthomyiid in Whiteknights Park, Reading, UK on 2018-08-18.
In Michael Ackland's draft key to British Anthomyiidae it keys out to Delia criniventris but the genitalia do not match.
In particular each cercus has a triangular backward-pointing 'tooth' on its inner edge.
Has anybody got any suggestions?
