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.
Enjoy the site and keep helping to build it up to a significant entry point for dipterological research.
The Diptera type material stored in the The Finnish Museum of Natural History (MZH) are being catalogued. A partial list of types with detailed -- and largerly previously unpublished -- information about the type localities etc. can be found at
The data it not dynamically updated but extracted from the museum databases every few months. So any corrections to reported errors (I'm sure there will be some!) will not be immediately visible on the Web pages. Happy type-bug hunting, everyone :)
30th meeting of the German Dipterists, Blankenheim, 28-30 June
The 30th field meeting of German Dipterists Association will be held at Blankenheim, roughly 50km southwest of Bonn, North Rhine-Westphalia, Germany on 28-30 June 2013. Everyone with interest in Dipterology is invited to attend the conference. Beside fly talks and excursions also the visit of the research collections in the Museum Koenig is offered. More information can be obtained from the AK Diptera website.
Today I learened that the eminent chironomid specialist Ole A. SĂ¦ther passed away last week. If I receive more information telling you about the life and works of this excellent researcher, I will post it here. In the mean time you have a look a the WikiPedia page on Ole at http://en.wikipedia.org/wiki/Ole_A._SĂ¦ther (also the source of the photo).

This isn't Scellus notatus, which is a species with conspicuous spurs and hair brushes apically on the tibiae and in the male creme coloured genitalia. It is rather something like Hydrophorus cf. nebulosus with spotted wings and sort of abbreviated abdomen. View Photo Comment

Scellus notatus is the only British member of the genus so your fly must belong to another genus - but, I confess, I have no idea what it could be. View Photo Comment

The three species O. germanicum (Duda, 1932), O. gilvipes (Loew, 1858), and O. cognatum are extremely difficult to distinguish. The image shows a shining humeral callus (= shoulder), a largely dark gena, a slightly flattened thorax, a wing only slightly longer than the abdomen, a completely yellow hind tibia, a frons darkened aside of the ocellar triangle, an ocellar triangle very long and with pollen (= pubescence) only aside and in front of the ocelli, a triangle not touching the eye margin, about Âľ width of the frons between the eyes, tergites glabrous, wing membrane partly yellowish, R4+5 apically slightly divergent with M1+2. All these characters here observable are not sufficient but typical for a distinction after the unpublished study (of much material including the types of gilvipes and germanicum) by M. von Tschirnhaus.
This is a typical species of the genus Oscinisoma Lioy, 1864 (Chloropidae, Oscinellinae), partly wrongly spelled Oscinosoma. The mesonotum (= scutum) is slightly depressed and not smooth but it has a rough surface. The adults prefer the stratum close to the soil between Carex tussocks, running ant-like and living together with the raptorious Stilpon spp. (Hybotidae). View Photo Comment

Chlorops strigulus (Fabricius, 1794), (Chloropidae). This robust species was long time included in the genus Anthracophaga Loew, 1866, now a synonym of Chlorops. It is extremely similar to C. frontosus Meigen, 1830, most old records need re-examination. Characteristics (frontosus in brackets), unpublished results of M. von Tschirnhaus: base of arista black (yellowish-brown), behind outer vertical bristle (vte) the whole lateral occiput downwards yellow (below a yellow area eye margin black), acr dense, in the line of the dc inserting on black points (scarce, on yellow ground), palpi short, excavated dorsally (long, normal above), 3rd antennal segment bicoloured (black), tergites dark until their ventral edge (lateral yellow, ventral black again, thus, two lateral stripes), scutellum slightly triangular (widely rounded), all femora more or less black, knees yellow (femora yellow with dark spots/striations), narrow dark line from the lowest point of the eye to the edge of the gena (such line absent), epandrium and surstyli bigger than the compared species (smaller). Larvae produce galls in certain Poaceae (frontosus: reared from Carex). View Photo Comment

I just noticed this on the list of gallery submissions and thought ah.. However, is there one similar to this, perhaps from another genus, but which has extra brushes on the inside of mid and hind tibia as well? Very conspicuous, and I can't see it here

Lipara sp., Chloropidae. Image unsufficient to identify the two following species: L. pullitarsis DoskoÄŤil & ChvĂˇla, 1971 and L. rufitarsis Loew, 1858 are very similar, after the literature only separable after the male (and also female) genitalia. Unpublished observation by M. von Tschirnhaus: L. rufitarsis: the 3rd tarsal segment of the fore- and mid-leg is longer than wide and longer than the 4th segment; the tips of the femora are wider yellow, especially dorsally, the veins of the wing base are yellowish (not brownish), the keel between the antennae is not wider than the diameter of a palpus, the pubescence of the eyes is whitish-grey (not dark). The larvae of both species produce galls in reed stems (Phragmites australis) which are not lignified and, thus, suffer heavy attack during the winter by the blue tit, which is feeding on the larvae.
