Has anyone ever explored using phorids as feeders? With my roach colonies and various other animals, phorids are an expected nuisance. I've found a way to trap a significant amount of them daily, a simple deli cup with dog food and a few holes in the lid, as an attempt to cut down their numbers. I was thinking that the captured flies could serve another purpose as nymph food. They're much larger than the fruit flies that I have and tend to run as opposed to fly. Has anyone had any luck with them?
