Gw, I read all 19 pages and I too am now captured by this small insect. I am wondering if you ever set up the pvc pipe over your pond? I would be very interested in this setup as I have tons of garden waste every year. Rotting tomatoes ect.. I would love to be able to feed my fish these lovely insects and get rid of so much garden waste at the same time. You have no idea of how many vegetables I have that just get tossed because we do not have enough time to process them all. I would like to run a pipe along my dock and let the little guys just drop straight into the water. I am sure after some time that would be an excellent place for an easy catch for the kids. I am located around Leavenworth Kansas and I am pretty sure I have seen these flies once or twice in the summer. Anyways please update on your progress with the pipe. Thanks, John
