I have found this pupa in or along the banks of a brook in the northern part of the province of Limburg, The Netherlands on 10.vi.2013. It was collected using a pondnet, so the exact place in the brook is unknown. I'm not how to name this species and I hesitate between Athericidae and Rhagionidae, but in my opinion it comes closer to a Rhagionidae. Any idea? atylotus attached the following image:  [73.96Kb] |

Though you have not included a full lateral view, I think it corresponds rather well with the pupa of Rhagio scolopaceus in Die Fliegen. I assume other Rhagio will be similar.

Aquatic habitat favors Athericidae. The only key to fly pupae I have covers aquatic families only and does not include Rhagionidae. http://books.goog...;lpg=PA525 (link to older version; the latest version adds a purely New World family) |

Hello People, I think Rhagionidae. Stubbs and Falk 2001 British Soldierflies and their allies give a key to the pupae of Athericidae and Rhagionidae. Rhagionidae should have: "Segments with at least the dorsal surface displaying a better developed partial ring of bristles or spines." Athericidae on the other hand: "Abdominal segments with few isolated spines." The size points to the smaller Rhagionidae like Chrysopilus. Greetings, Ectemnius |
