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.

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. :)
