Provisional atlas of British hoverflies (Diptera, Syrphidae), Ball, S.G. and Morris, R.K.A. 2000. 167 pages. ISBN 1 870393 54 6.
Published by Biological Record Centre, CEH Monks Wood.
Maps of each species based on observations submitted to the Hoverfly Recording Scheme to about 1997. The maps show 10km squares of the OS National Grid (for Great Britain only) from which a species has been recorded. A histogram is also shown showing how many records were recorded in each fortnightly period. |
