[Syrphidae] Catching females!

[Pavel Láska]

In past I obtained the material from larvae. I collected the parts of plants with aphids in cages, and after two or three I seek the larvae. In the summer time in Czech are aphids in Cichorium intibus or Crepis biensis along ways (Uroleucon cichorii). With best wishes     Pavel Láska

  Hello,

  I am about ot begin my first years PhD research and will be constructing food chains in the laboratory. I would like to culture the hoverfly Syrphus vitripennis but think I may have collected only males.

  I understand from my I.D guide that male's have eyes that are 'together' when looking down onto their (top) dorsal side, whilst females have a gap. However, I have so far only been able to locate conspicuous males hovering or basking in good numbers around the hedgerows. 

  I wondered if anyone had any good tips for finding where the females are hiding (or any less dubious I.D techniques)?

  Any advice would be great!

  thanks,
