ok. I decided for a Syrphidae book. There are no Nemestrinoidea books :( neither Stratiomyidae (hmm... ok. they have "A Biosystematic Study of the European Stratiomyidae " very expensive! and they have the world catalogue), Conopidae (only one book - precisely the german book with those 2 genus).. and Tachinidae with older and not updated versions.. :(
Bombyliidae... I would like this one: "Bee Flies of the World:" but it costs more than ?30 :D In next time. :)
That's why I decided to chnage for Hoverflies of Northwest Europe: bY Mark Veen. Even the spiders' books no one interests. :(

I think nbhs store has much better books but they are more expensive.
