Fruit Fly Cultures Care, How To, Using and Making
Introduction: Fruit flies are the go-to feeder insect for small carnivorous pet bugs, reptiles, amphibians, and many other small pets. There are several varieties on the market but the main two are Drosophila melanogaster and Drosophila hydei. Though the care for these two species is the same, which one you choose depends on what you're feeding them to. In both cases, most of the varieties that are available online are not capable of flying like the wild fruit flies that visit your fruit basket in the warmer, summer and fall months.
Fruit flies have a long history in this country as feeders and for studies in genetic inheritance in laboratories. We owe our wingless cultures of feeder Drosophila melanogaster to this science. The fruit fly is a model organism for these studies because they reproduce new generations very quickly, in as little as about 7 days. Cultures ship with adult flies and usually, these have already laid eggs in the food media at the bottom of the cage. Often, larvae are already wriggling around through the half-inch or so of food media at the time of arrival too. Within a week, eggs hatch, larvae grow larger and then pupate (little cocoons they paste to the sides of the container), and finally fresh adults emerge from these pupae/cocoons. Both of the commonly available species of fruit flies on the market are able to climb up the smooth surfaces of glass and plastic tank walls.
Drosophila melanogaster is the smaller of the two popular fly species on the mainstream hobby market. These tend to be genetically modified to be apterous (completely absent of wings). They are the go-to option for the smallest carnivorous pets.
Drosophila hydei have 2 to 4 times the mass of D. melanogaster and so they are the next step up for pets that have grown just slightly too large for the D. melanogaster. Most D. hydei cultures are available for sale on the open market are genetically modified so that the musculature of the wings is inoperative. They have wings but they cannot fly. At best they can sort of hop around a little bit, making them highly attractive to your predatory pets.
