Stubbs, A.E. & Falk, S.J., 1983
British Hoverflies (ed 1)
Introductory chapters cover observing, studying and photographing hoverflies; collecting; habitats and seasons; the early stages and the characters of adults.
The keys are very well illustrated and cover groups, genera and species of the adults. The species accounts concentrate on ecology, field craft, distribution and history of records, rather than morphology, although hints on distinguishing related species are included. Phenology of the adult is also given.

||All the British species known at the time.
||Numerous line drawings accompany the keys. At the back are 18 plates of line drawings and 12 beautiful colour plates of paintings of 192 spp by Steven Falk.
||Under a Stereo Microscope.
||Most of the larger species can be identified alive, but the rest must be pinned and set, with male genitalia extended in Sphaerophoria and Cheilosia.
||The majority are straightforward, but Cheilosia is challenging. External genitalia needed in some genera.
