This Limoniidae pupa was found along the shore of a strongly brackish to salty lake on the Isle of Voorne-Putten in the south-west of The Netherlands (lake Oostvoorn=Oostvoornse meer) on 28 september 2009. HAs anybody has any idea about the genus?.
There are no signs of spines on the tergites but only rows of posterior spines on the sternites. Also no spines on the mesonotum.

Dear Stephen (and Karl)
I'm able to make some more pictures on friday. Could you be more precise in what ventral detail you need? is it the anal segment, the entire abdomen or a specific sternite?

I never try to determine somebody from pupa myself. I have now a pupa of Symplecta hybrida. I join its photos here. The end of abdomen is similar, horns are similar but the 1-2 pairs of legs in my case are at one level and the third pair - at another - this is the difference.

Some time ago I was fond of Diptera living in salt waters. As for Limoniidae - at least he genera Dicranomyia, Geranomyia and Pilaria were reported. Later I noticed that many salt-liking Diptera (Ephydridae for example) inhabit hot springs. As for this Symplecta was from Kamchatka hot spring I desided to look at it.

Sorry, Atylotus, I was only looking at this aesthetically! Karl Blossfeldt was a photographer who specialised in natural forms as inspiration to artists, including sculptors and architects, in the early 20th century. See http://www.karl-b...archiv.de/
Your ventral photo of the thorax showing the legs and wings is just the sort of thing he would have done, except that he specialised in plants.
Bad manners on my part not to make it clear what I meant. :(

As you might have guessed already, I was just thinking: Karl who? I think that my Symplecta pupa (thank you for that Cranefly) is also a piece of art. A Limoniidae pupa living in salty water at a rocky place with mass amounts of macro-algae (and swimmers and divers and surf and...), no trees, no vegetation nearby, only rocks and dry sand is just incredible. Why should you pupate here?
