British fly miners
Keys to mines
Provisional keys are provided for dipterous mines for 311 of the 786 host plant genera discusssed, although some of the records require confirmation and some of the records are based on non-British associations. In addition 103 links to keys for related genera are included. More than 6,450 fly/host plant or putative host plant associations are included, although only 2,067 of these are based on British records. Scientific and common names of host plants follow the Botanical Society of the British Isles (BSBI) checklist.
Access to the keys is provided by scientific and where possible by common name (only about 52% of the vascular plants recorded in Britain have common names). Many of the fly/host associations are based on host genera and only 639 of the recorded British host plant species have common names
A single page is devoted to each species of fly. Where known, the life-style of all included species is given along with a description of the mine and diagnostic characters of the larva and puparium; the host preferences in Britain and elsewhere; the time of year when mines (or larvae) and adults may be found in Britain; and the known distribution.
