I have the necessary literature not available here. I will check at the office tomorrow, but maybe someone will beat me to it (Robert?). Any background info?

I obviously am not in the least able to help B), but I wanted to welcome Gabriella who is one of quite a few of my fellow "NaturaMediterraneo" colleagues who have been finding their way here recently. Good to see you Gabriella, Sarah.

Checking 'A guide to the breeding habits and immature stages of Diptera Cyclorrhapha' (Ferrar, 1987) it could be that species, based on the posterior spiracles. The other features are not illustrated in that book. If you rear the specimen from pupa, please post the picture of the adult. ;)

This morning I had a look at the figures in Peter Skidmore's "Biology of Muscidae of the World", and it certainly matches Muscina very well. Not exactly the same as the picture of stabulans mouthparts, but close enough allowing for individual variation. Depending on where the puparium was found, I'd go with Muscina stabulans.

Thanks to Sarah for welcoming me in this new nice site.

The pupae have been collected from a carcass found in a ground hole, during the last Jun. Unfortunately, no adults have emerged from my pupae till now. Thanks to Paul Beuk and thanks to Tony Irwin for his information about the fact that my pupa is a Muscina one.
Please, may I have a new information? In the Muscina case, do posterior spiracles modify in significantly way during the change of the insect from the larva stage to the pupa stage? Some specimens of Muscina stabulans that I have found have posterior spiracles very different from those I can observe on the relevant pupae.

Many thanks again for your kind help!

Gabriella

No definite id yet. And I must write a detailed response to your question. We are moving the museum collections and library for the next month and therefore I have no time. Please wait.
