<DIV><FONT size=2 face=Arial>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 </FONT></DIV>

<DIV dir=ltr><FONT color=#000000 size=2 face=Tahoma>Hello,</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma></FONT> </DIV>
<DIV dir=ltr><FONT size=2 face=tahoma>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 <EM>Syrphus vitripennis</EM> but think I may have
collected only males.</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma></FONT> </DIV>
<DIV dir=ltr><FONT size=2 face=tahoma>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. </FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma></FONT> </DIV>
<DIV dir=ltr><FONT size=2 face=tahoma>I wondered if anyone had any good tips
for finding where the females are hiding (or any less
dubious I.D techniques)?</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma></FONT> </DIV>
<DIV dir=ltr><FONT size=2 face=tahoma>Any advice would be great!</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma></FONT> </DIV>
