The Society for the study of flies (Diptera)

The Mycetophiloidea includes the families Bolitophilidae, Diadocidiidae, Ditomyiidae, Keroplatidae and Mycetophilidae with 531 species.

These flies can be abundant, especially in the autumn when many other flies are scarce. They are often plentiful in woodlands and wetlands, particularly in sheltered nooks and crannies and around fruiting bodies of fungi.

While some groups within these families are manageable, generally they are difficult unless you are prepared to spend time really getting to know them. There is a RES Handbook to the families other than Mycetophilidae which should be supplemented by subsequent papers, while manuscript keys to many Mycetophilidae are available from the scheme organiser on request. You will need a good microscope, the ability to make preparations of the tiny genitalia and the patience to assemble all the dispersed literature.

Many species new to Britain are being found, so if you relish the prospect of discovering some yourself these flies may appeal to you. Fungus gnats are not to be taken on lightly but the scheme organiser will be happy to assist those starting out.

Peter Chandler welcomes samples for identification either pinned, in envelopes or in alcohol depending on source.
