<DIV> </DIV>
<DIV>Thank you for your valuable advice ! I do not have chemistry lab, I work in my living room -:)</DIV>
<DIV> </DIV>
<DIV> I noticed that the ethyl acetate caused enormous damage to the tissues of the hoverfly. Now I catch dry ! I ignored the need to avoid several specimens in the same pot. I tend to do that because I am interested also in wild bees, wasps and bumble. I'll have to change my habits -:)</DIV>

<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><SPAN lang=EN-US style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'sans-serif'">I have tried acetone, but I don’t recommend it. Specimens get extremely brittle. </SPAN></DIV>
<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><SPAN lang=EN-US style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'sans-serif'">Instead, you could try amylacetate. Very smelly stuff (reminiscent of winegums, some people like it), but reputedly harmless. Soak the specimens for 24 hours and then dry them. This is also a reasonable method to ensure that specimens that have previously been kept on alcohol keep their body shape. With small specimens you should pin them before you put them into the liquid, because otherwise there’s a big chance that the head will roll off.</SPAN></DIV>
<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><SPAN lang=EN-US style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'sans-serif'">Before putting them in amylacetate, you could consider soaking the specimens in a mixture of ethanol and xylene for 24 hours. This degreases the specimens, which increases the chance they keep a good colour (although they tend to get a shade paler). However, xylene is said to be carcinogenic, so I don’t like to use it at home. </SPAN></DIV>

<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><SPAN lang=EN-US style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'sans-serif'">A way to prevent syrphids losing their colours without using chemicals is to try to keep them as dry as possible. So don’t use too much ethyl acetate in your killing jar, don’t put too many specimens in one jar, don’t leave them in too long, keep it out of the sun etc.</SPAN></DIV>

<DIV>Hello every one,</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I appeal to the experience of members of this list to see if anyone has a technique to keep the colors of hoverflies. I found that some specimens lose their color when dry. Does anyone has tried acetone? It seems that acetone bath permetra fix the color ? What do you think ?</DIV>

<DIV dir=ltr><FONT face=tahoma size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=tahoma size=2>Sorry to trouble you, I am trying to catch female Episyrphus balteatus so that I can produce a supply of eggs in the lab. However I am having trouble finding any. I have located and caught plenty of males hovering under trees and bushes in hedgerows and parkland, but an extensive search of hedgrerow flower banks and buttercup fields has revealed no females. I wondered if anyone had any good tips for finding females - such as their favourite habitats or food plant species? I have managed to collect many female Syrphus ribesii amongst nettles and flowers in sunny hedge banks...but no Episyrphus.</FONT></DIV>
<DIV dir=ltr><FONT face=tahoma size=2></FONT> </DIV>
