Found near Szeged, S. Hungary, on 01. 05. 2012. Is it possible to ID this Eurina sp. (my best guess is E. ducalis), based on these pictures? Thanks for any comment! Henrik Edited by piros on 14-01-2013 12:49 |

I found a key and descriptions of Eurina here: http://archive.org/stream/chloropidaeeinem00beck/chloropidaeeinem00beck_djvu.txt Based on this (and according to my understanding of it) the fly above should be Eurina ducalis indeed. A year earlier, and a nearby, but different site I found another Eurina, which I thought was calva. I attache a few pictures of it below. |

I would greatly appreciate confirmation of these IDs, especially that of E. ducalis, because, according to Fauna Europaea, this sp. is not known from Hungary, and I do not have any experience with this group of flies. Thanks in advance! Henrik Edited by piros on 22-12-2012 16:25 |

Unfortunately I don’t have this species (E. ducalis) in my keys, but according the site that you introduced (although is German and used translator for), I think you are right; Then, I think name of both species are true.
Sincerely yours Sara |

Eurina calva Egger, 1862 (Chloropidae). Though there occur only 7 Eurina spp. in the Palaearctic, they are not easy to identify, e.g. partly after the key of Duda 1933 in Lindner. After the unpublished experience of M.v.Tschirnhaus in E. calva the setulae on the ocellar triangle arise from 4 or more rows of dark punctures lateral of the central groove, being light and very short (ducalis: 2 (or 3 incomplete) rows; deep black and relatively long), and the setulae on the scutum are dense and light (ducalis: deep black). The 2nd antennal segment (as mentioned in the literature) is not longer than the 3rd (ducalis: slightly longer). The species may develop in the root system or shoots of Phragmites australis (Poaceae). The three species triangularis Becker, ducalis Costa and calva were swept together on young reed shoots in Greece by M.v.T., though ducalis is known to produce galls on Scirpus tuberosus (Cyperaceae) and larvae of triangularis are boring in the stems of the same Scirpus host-species.
