Location: Chongwe district, Lusaka province, Zambia.

Habitat: Shaded pond heavily populated with Nile Cabbage.

Date 21/02/2013 - 26/02/2013.

size - 8-10mm.



A similar fly, photographed in Kafue National Park back in 2011, was identified by Jan Willem as Diasemopsis (or Chaetodiopsis) meigenii, in this post: http://www.dipter...d_id=44508

Might this be the same?


[Edit: - it is the same. Thanks again, Hans Feijen and Jan Willem]

Nobody feeling like stalk-eyed flies today?

Hello Will,

Hans Feijen, a specialist in Diopsidae, told me that this is a specimen of Diasemopsis (or Chaetodiopsis) meigenii. Probably a female. Diasemopsis (or Chaetodiopsis) meigenii is one of the most common species occuring from South Africa upto Arabia.

Fourteen month deja-vu - thanks, Jan! I shall update the title accordingly.

I suppose the differences in structure (thicker limbs, eyestalks) in the previous pictures (http://www.dipter...d_id=44508) are male/female variation, or just variability within the population?

Thanks again,

William.
