Hello, On May the 16, I found some Diptera females ovipositing on Cyclocybe aegerita growing under an old stump near a river (650m alt, Auvergne, France). the body length without wings was 5 mm. I thought it was an Heleomyzidae because antennae short, arista very long, vibrissae, costal vein spinulate, subcostal and R1 veins divergent, anal vein long, posterior tibial setae present Heleomyza because more than 1 pairs of vibrissae. And maybe Heleomyza serrata (but it's not). Or maybe it's an Anthomyiidae because the anal wing vein ends on the margin? A Pegomyia? Because it's look like the specimen of this post : https://diptera.i...pid=220248 I have kept a specimen in alcohol if you need more details. If you have any documents references (Doi, book) on Anthomyiidae, me and others are interested, because it seems to be few of them. Thanks in advance.

Anthomyiidae. Many species of Pegomya breed in mushrooms. |

Thanks John Carr. Can you say why its an Anthomyiidae and if you know some publications to determine the species? |

Could it be Pegomya calyptrata (Zetterstedt, 1846)? |

I do not have references for European species. The crossed interfrontal setae and the arrangement of bristles on the hind tibia are typical of Pegomya. About half the species (subgenus Phoraea) breed in mushrooms. The others are leaf miners. There is a group of fungus-feeders with enlarged lower calypters. Most of them (the P. winthemi species group) have enlarged fifth tarsomeres, not visible here, but some do not. |
