[Syrphidae] Canopy research

[Julio Cesar Rodrigues Fontenelle]

Dear all,
	I just start to write a project with canopy insects in a temperate forest
in Southeast Brazil. I work with Diptera and I'm interested in use some
kind of trap to catch manly large flies, like hover flies, muscoids,
soldier flies etc.. I'm not interested in use attractants.  I will try to
make some trap like a small Malaise with the killing jar in the middle of
the trap. But I don't know how to do the entrance of the killing jar.
Thanks very much if you can help us with some ideas.

			Your sincerely,
						Julio Cesar Rodrigues Fontenelle
