The Diptera ("di-ptera" = two-winged) or "true flies" is the largest order of animals in the UK with around 7,000 known species and new ones being discovered every year. They are found in all habitats from the sea shore to mountain tops. Whilst some are agricultural pests or vectors of disease, the great majority are beneficial. They are extremely important as predators on other pests and diseases, as pollinators, as food for other animals and the immature stages of the bulk of the species are involved in the decay of organic matter and the recycling of material back into the soil.

Entomologists who specialise in these insects are "dipterists". In 1993, a group of people who wanted to find out more about every aspect of their lives, including the habitats they require, set up the Dipterists Forum. There is a great deal still to learn about flies. Mapping the distribution of some groups is a major achievement of the Dipterists Forum to date, but the immature stages of the majority of species are still unknown. Many species are becoming increasingly rare as a result of habitat loss and climate change.

Why not join the Dipterists Forum and help us find out more about flies? There is so much still to learn; we welcome beginners and there are always people who can help you out in the early stages. You don’t need to be an expert, or even to leave your own garden, to contribute to our knowledge of these fascinating insects. Flies need your help! Read more ...

Spring workshop: Sciomyzids

I am working on an updated key and species accounts for the spring workshop at Preston Montford on 18/19 Feb. This document includes distribution maps and phenology plots. If you have any records in computerised format, I would appreciate a copy to include in this analysis. These maps and charts will be very much "warts and all" - i.e. they have not been checked or validated by the recording scheme! If you have data in MapMate or Recorder then a transfer file would be good (zipped mdb file from Recorder, .sqz file from MapMate). Otherwise, a spreadsheet is ideal with one record per row and columns such as species name, location name, grid ref, vice-county number, date and comment (and recorder and determiner's name if they are not all your own!). Please email such files to me at stuart.ball@dsl.pipex.com.

Changes to Constitution concerning the name of the Forum

At present, section 1 of the Constitution reads: "The Organisation shall be called the DIPTERISTS FORUM, hereafter referred to as the Forum."

The following is proposed  as a replacement: "The formal name of the Organisation shall be the DIPTERISTS FORUM, hereafter referred to as the Forum. In less formal situations the Organisation may be called THE SOCIETY FOR THE STUDY OF FLIES (DIPTERA)."

This proposal will be voted upon at the Annual General Meeting to be held on the 26th November 2016 at the Natural History Museum in London.
