Definitely an interesting result. Obviously, I have a real interest in this so, of course, I have lots of questions! smile

Was the black trap one of those "plastic" covered ones? Were the openings the same size and config. in the two traps? (The black traps I've seen have a ring at the opening while the Gee traps I use have exposed wires.) Did you run your tests during the day or night and do you think it would have made a difference? If daytime, sunny day or cloudy? If you trapped in a stream, was one trap always place "upstream" of the other or were they alternated. ..... Any details you can remember would be of interest to me.

Thanks!
