Hello,

While looking for Coleoptera living with ants, one member of our french forum found those Diptera larvae :

As the larva was trying to leave the nest, the ants brought it back.

Any clues ?
Somebody proposed a Volucella larva, but they are noted to be hosts of bumblebee and wasp nests. Not of ant nests.

Hello,

Another solution was proposed with Clitellaria ephippium, which is recorded as a parasit living in ant nests.
Does this ring a bell?

it's definitely not a stratiomyd, for it has no leathery skin. As I'm only an aquatic larvae expert this terrestrial larva looks a bit like a Sciomyzidae or a Muscidae. But perhaps maybe also something like a Phoridae or any other Cyclorrhapha. For instance, it is know that some Phoridae larvae parasitize trhe pupae of Formica (Aenigmatias) or are parasitoids of adult worker ants (Pseudacteon) (see Smith, K.G.V. 1989, immature stages of British flies)

Hello,

Thanks for your comments. I'll have a look at this book on immature stages of British flies. I happened to buy it for peanuts on ebay.
