[Syrphidae] need help with the conservation of hoverflies

[Pierre MILLE]

Hello every one,
 
 
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 ?
 
Best wishes
 
Pierre

Hello Matt, 
In Sweden a favorit plant for females to lay egg on is Phragmites communis. So maybe your are lucky on fresh leaves of such stands and in their vicinity 
Best wishes

Subject: [Syrphidae] Finding Female Episyrphus


Hello,
 
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.
 
Any help would be greatly appreciated as Im waiting on them to construct food chains in the lab.
 
Kind regards,
