Bonjour, I'am an ant keeper from Québec city. From time to time, me and other keeper have queen killed by parasites. The most interesting is a fly that lays eggs in the abdomen of the queen. The queen remains alive for several months before the pupa appears. I never observed it to leave the abdomen. Here are some picture of that situation.

The fly is a Tachinid, so family Tachinidae. Subfamily Phasiinae, and I think even in the genus Phasia! Greetings Greetings, Gerard Pennards |

Hmm, yes ... not Phasia, though the venation is similar. I think Strongygaster is a good first guess, considering the host, and it is listed as a Nearctic genus

Amazing job, excellent, Strongygaster it should be, only Tachinid from ants in the Palaearctic. It is the only genus in Strongygasterini in the Nearctic catalogue. SO there can be little doubt (and the best argument of course: it looks like a Strongygaster !) Theo |

Jim O'Hara in Canada will be able to give a name if you send him the specimen and I'm sure he would be very interested in the host record too
