Welcome to the site

This is an interactive site for dipterists from all continents dealing with all aspects of dipterology (the study of Diptera: flies and midges) and dipterists. Here you can submit all your links to dipterological websites and events, post your dipterological queries in the forum, submit articles and news on Diptera, and contribute pictures for the Diptera Gallery. Submissions are open for members and members can contribute to the forums.

If you are dyslexic, please, select the 0_Dyslexia theme in the Theme Switcher panel in the left column.

Enjoy the site and keep helping to build it up to a significant entry point for dipterological research.

Thank you! Despite the incease in hosting costs the donations up to Christmas Eve covered more than 90% of the costs for the running the website this year. Like I said last year 'We will manage' and so we did. Together we will continue the good work in the coming year. ;) [24 December 2020]

Negrobov Oleg Pavlovich (November 21, 1941 - January 8, 2021) passed away
This message was received from Igor Grichanov:

On January 8, Oleg Pavlovich Negrobov, Doctor of Biological Sciences, Professor of the Chair of Zoology and Parasitology of Voronezh State University, passed away. His whole life was associated with the Voronezh University, Russia, where he held the Chair of Ecology and Systematics of Invertebrates for many years.

Oleg Pavlovich was born in Voronezh. In 1959, he entered the Faculty of Biology and Soil Science of Voronezh University, which he graduated with honors. During his studies, Negrobov took part in a number of expeditions to the Caucasus, the Kola Peninsula and the White Sea. In 1964, Oleg Pavlovich entered the postgraduate course of the Zoological Institute of the USSR Academy of Sciences in Leningrad, where he prepared a thesis for the degree of candidate of biological sciences (PhD) under the guidance of the famous entomologist Professor A.A. Staсkelberg. The work was defended in 1968. And from the end of 1967, Oleg Pavlovich began working at the Chair of Invertebrate Zoology, Voronezh State University.

Since the first years of his work until the end of his life, he was engaged in research on dipterans. And he was one of the world's leading specialist on the long-legged flies (family Dolichopodidae). He described 13 new genera, about 510 new species and subspecies of this family.

In 1983, Oleg Pavlovich defended his thesis for the scientific degree of Doctor of Biological Sciences (DSc in Biology), and since 1986, he took the position of professor of the Chair of Invertebrate Zoology. Later he became the head of this department, which was transformed under his leadership into the Chair of Ecology and Systematics of Invertebrates. Since September 2020, after merger of two zoological departments, he became a professor at the Chair of Zoology and Parasitology.

See the list of new taxa of Dolichopodidae described by O.P. Negrobov here.
Flower Flies of Northeastern North America
In mid-May this year, our Field Guide to the Flower Flies of Northeastern North America was published ( This book covers all syrphids found from Tennessee north to the high Arctic (including Greenland) and west to roughly the Mississippi River. All 413 known species from this region are included in the guide. In addition to providing identification information on the species, it includes many previously unpublished things (new synonyms, new combinations, undescribed species, DNA evidence for taxonomic decision making, etc.). The book includes many photos of each species (both lab and field photos), maps that include dots for the exact records as well as predictive ranges, silhouettes showing the actual size of the animals, ecological information, etc. There is also an extensive morphology section, glossary, checklist and bibliography.

It is published by Princeton and available from most book sellers (including Amazon, Indigo, Veldshop, Pemberly, etc.).

We hope that you enjoy it and help fill in the many gaps in our knowledge before a second edition.

German Diptera Meeting 2019
MeetingsThe 36th meeting of the German Diptera study group (AK DIPTERA) is going to take place from 31.05.2019 to 02.06.2019 in southwestern Germany, near the Danube Sinkhole near Tuttlingen (state of Baden-Württemberg). The meeting consists of a scientific symposium on Friday, a Diptera collecting field trip on Saturday, and an optional historic excursion on Sunday (castle Granegg and Beilstein cave). As the venue is located close to the FRENCH and SWISS border, we would be delighted to welcome some of our neighbouring colleagues! If you are interested to participate, send me a PM and I will send you an English version of the registration form with additional details.

Kind regards,

New book: The robberflies of Germany
Finally it is done! The nature guide "The robberflies of Germany" has just been published (in German language):

Many thanks to all of you, who contributed to this book with their faunistic data of asilid findings (pictures) from Germany.

Chlorops strigulus (Fabricius, 1794), female or Chlorops frontosus Meigen, 1830, Chloropidae. Both species are very similar. This seems to be the more abundant C. strigulus. In a Chlorops key of Dely-Draskovits (1978) C. frontosus was omitted together with several other Chlorops species.

Hallo, I have a question. Are there any hidden rules in this forum? Do you have to upload spectacular flies to get answers? As soon as the inquiries slide to page two or further, they rest gently

No idea what happened but it is corrected
