Within a large batch of Molophilus short-palped craneflies, one was a hermaphrodite - with dorsal female genitalia located above male genitalia. Does anyone have any info. on the occurrence of this condition with Tipulids or other Dipteran flies ? |

The cover of issue 22 of the newsletter Chironomus has a photo of a gynandromorph Chironomus dilutus with one side male and the other female. A related phenomenon leads to "chimera" humans with two sets of DNA mixed in irregular patterns. This can show up as stripes under appropriate lighting. |

A gynandromorphic bibionid was recorded here: Vlug, H.J., 1982. Een geval van gynandromorfie bij Dilophus febrilis (Linnaeus) (Diptera: Bibionidae). - Entomologische Berichten, Amsterdam 42: 102-103. Paul - - - - Paul Beuk on https://diptera.info |

Coincidentally, this week I found an intersex Chironomus with male sexual organs on a female body. I submitted a photo to the gallery. The condition is caused by a nematode parasite rather than an embryonic developmental defect. |

Thanks, John! I also recently found a chironomid with male genitalia and female antennae. I didn't know what caused it - now I do.
