The Society for the study of flies (Diptera)

Hello,

I am a PhD student at the University of Nottingham. I am working on Batesian mimicry. Part of my research involves quantifying the colour patterns of particular species of hoverfly (see list below) using photographs. My aim is to see whether the patterns vary across Europe.

Basically I need help. I have exhausted the collection at the Natural History Museum, London and need more data. Do you have/or know of anyone who has photographs and/or collections that include the species listed below? I would be extremely grateful for any help.

Thank you for reading,

List of hoverflies being used:

Syrphus ribesii
Chrysotoxum cautum
Chrysotoxum arcuatum
Xanthogramma pedissequum
Eupeodes corallae
