I've purchased some blue bottle flies and I just have a few questions. I've already done a search and found some great info but still wondering about a few things. Do the flies grow any bigger after the pupae hatch? How long will the unhatched pupae keep in a 38 degree refrigerator? Also any tips on a hatching cup would be appreciated. I've made my own version of the cup-o-flies from mantisplace.com, but I've made my own food which is a mix of powdered milk, sunflower honey and bee pollen, and I'm going to try watering gel for a water source.
