I just had to vent. I don't know how it happened but suddenly my melanogaster cultures have all developed the ability to fly. I have been using this same line of flies for 2 years now, with no problems. Now suddenly every culture (except one) has a few fliers. Hopefully I can use that one culture to start up everything again. In the mean time I will feed off the fliers and hope to get everything back to normal. Any ideas how this could have happened?
