I think it is more like D. aestivalis. At the base of the anal lobe you'll see a dark lateral stripe, which is unique for D. aestivalis, at least for the known larval species |

Hi Atylotus, Thanks for comment I have only key : Rozkosny 1980 (Klíč vodních larev hmyzu) see photo I don't know, it is still actual... but most similar is only amphibia.... what do you think ? Many thanks. Jozef Jozef Obona attached the following image:  [139.23Kb] Edited by Jozef Obona on 30-11-2012 14:45 |

poor drawings If the posterior border of the basal platelet has a median expansion and the body is not hairy (see my photo of filicornis in the gallery http://www.dipter...to_id=5496 and the photo of amphibia in the other message) than it must be amphibia. But this is not the case in your specimen. Furthermore I still can see a lateral stripe (see also my photo of an aestivalis specimen in this message). You can check this if this is true for your specimen. If not, than it is something else (including autumnalis). atylotus attached the following image:  [181.17Kb] Edited by atylotus on 30-11-2012 16:23 |
