Thanks Theo, that's far enough. I'm concentrating on phtographing and keeping all the flies I can catch and have time to process during the summer. Eventually I will get around to looking at them closely to try and get some level of identification. Your comments, and those of others, are great places for me to start and will save me lots of time and frustration. I realize that your ID are somewhat tentative based solely on photographs of "New World" species. I do appreciate your comments.
