I'm a PhD student at University of Jordan.
I'm conducting a research entitled: "Studies on common insects attacking animal cadavers in Jordan" I need a Key for Oestroidea (epically spices belong to Calliphoridae and Sarcohpagidae) for Palaearctic area.
Thank you :)

Right.

This is not so easy.
Of course you should start with Lindner (Fliegen der Palaearktischen Region). However, it is incomplete (Sarcophaginae not completed) and some chapters are really out of date.
On the other hand, you are probably most interested in only a few genera, like Wohlfartia, Lucilia, Bellardia and so on. So you could start from the biological point and puzzle out the genera you might expect.

For Sarcophagidae, Thomas Pape in Copenhagen is the leading expert.
For Calliphoridae, you might try to consult either John Deeming in Cardiff or Knut Rognes in Norway. Both are, however, to my knowledge quite busy at the moment.

For Calyptratae on living animals (Oestridae and Gastrophilidae), I am more than happy to help you out.


Good luck

Thank you Zeegers, I appreciate you offer for help me I contact with Knut Rognes and I have his book about my area (2002) for the Calliphoridae and I'm working to figure out the main characters to mach it to the fly body ;).
