Leucophora? If so, where might one find a key to take it further? On v old sedimentary stone wall near town centre in west of England last week. V distinctive in the field as it seemed so pale. sbushes attached the following image:  [228.55Kb] Edited by sbushes on 26-06-2021 02:10 |

Oh right, interesting... didn't realise the markings could be so faint. Many thanks John. According to this post should be either festiva or histrio then... - https://www.diptera.info/forum/viewthread.php?thread_id=23232 Will see if I can photograph the av-setae to resolve. |

Copying in Michael Ackland's post ------------------------------------------------ "EUSTALOMYIA Males and females 1 Legs and palpus partly yellow vittipes (Zetterstedt) – Legs and palpus completely black 2 2 Arista long haired, the length of the hairs on upper and lower side are each equal to width of postpedicel. Median vitta of scutum widened behind into a rounded spot hilaris (Fallén) – Arista short haired or pubescent. Median vitta of scutum equally wide throughout 3 3 The length of hairing on arista in total equal to width of postpedicel. Hind tibia with 7 av-setae festiva (Zetterstedt) – Hairing of arista significantly shorter, the arista is only pubescent. Hind tibia with 12 av-setae histrio (Zetterstedt)" ------------------------------------------------ If Eustalomyia then this seems to be E.festiva? sbushes attached the following image:  [63.36Kb] |
