Thanks - that was quick. I'm still waiting for my tachinid key to arrive. Nice pics on that page - there are some great Belgian websites about. Commanster a favourite : http://www.commanster.eu/commanster.html

Tachinids are tough... usually. Good luck with that! Yes, I've often come across commanster and there are some other great sites in Europe for various things, a German one for beetles http://www.kerbtier.de/ the Gallery pics on monde des Insectes http://www.galerie-insecte.org/galerie/ is really useful for all sorts and there's a great Czech site for many things too that I often stumble across but never know the url for.
