Other common names: Common Fruit Fly; Vinegar Fly
Scientific name: Drosophila melanogaster
The Common Fruit Fly is a small and common fly which is native to equatorial Africa, but which has now been introduced worldwide except for Antarctica. The Fruit Fly lives on plant material, and lays its eggs on slightly ripened fruit. Drosophila melanogaster has a short lifespan of around 30 days.
The Fruit Fly is widely used for scientific studies on genetics and developmental biology. Its popularity for research is due to its small size and ease of growing, the fact that it only has four pairs of chromosomes, and because its complete genome was sequenced and published in 2000.

"Fruit Fly culturing is a fun challenge
I take pride in my fruit fly culturing, because I have to keep myself motivated. It is tough!
I raise fruit flies to feed my poison dart frogs. I also use them as a snack/supplement for my green tree frogs, canyon tree frogs, green anole, and fish.
I keep my fruit flies in deli cups with a homemade media at the bottom for the flies to eat and lay eggs. The eggs develop into larvae and then cocoon before becoming adults.
I keep a smaller and larger species of fruit flies. The species are called melanogaster and hydei.
It really is rewarding to see my frogs grow big and strong all off of food I have provided without going to the pet store or relying on others (:
I encourage you to try this if you have pet frogs, spiders, fish, lizards, or other small critters that would snack on fruit flies. It is a fun challenge. Be prepared for failure initially. But you will get it down and feel like a boss!."

The Drosophila melanogaster is a fruit fly commonly fed to baby lizards, baby toads, poison dart frogs, insect eating plants and aquarium fish like Gouramis, Bubble Nesting Bettas, Apistogrammas, Epilaty Killifish, Corydoras and White Clouds. They can grow to be about ¼” in length. There is a difference between flightless and wingless fruit flies. The flightless fruit flies have wings, but they cannot fly. The wingless fruit flies don’t have wings, cannot fly and resemble small ants, but they are not. They can move quickly and you must be fast and replace the lid on your container or else they will all get out. Tapping the container will sometimes cause them to fall to the bottom of the container but they will quickly climb back up to the top in an effort to escape. So, be sure that your lid is properly secured and in place.
When keeping fruit flies, select a dark area in your room to keep your culturing container. Keep them at room temperature away from cool spots and drafts. You do not need to feed them once your container is set-up. When culturing them, choose a heavy duty 32 oz. deli container with a secure insect lid. You do not need to make any holes in the container since the insect lid will allow air to flow through.
You may use a commercial medium or make-up a homemade mixture of about ½ c. mashed potatoes, ¾ c. water, 1 tbsp. sugar and a mold inhibitor. Add more or less mashed potatoes to thicken your medium. It shouldn’t be runny. Allow your medium to sit overnight to stiffen. Add 4-5 micro pellets of yeast on the surface. Don’t mix yeast into your medium. Add Excelsior or Coffee Filter Paper on the surface of the medium for your flies to climb on.
The mature fruit flies will lay eggs that will hatch into fruit fly maggots. The maggots will crawl into that mash potato medium that I mentioned earlier and they will feed and grow there, then crawl up the sides of the container and pupate before becoming mature fruit flies and they will then mate and start the cycle all over again.
When you are ready to harvest your fruit flies, you can place your container in a fridge for a few seconds to slow down the movement of your flies, remove them from the fridge, quickly remove the lid and place your flies where you need them. Removing the larvae is a little more complicated because you’ll need to transfer your flies into a temporary holding container so that you can remove the larvae with a popsicle stick. When done, replace your flies.
Sub-Culture your fruit flies every 2 ½ to 3 weeks.."

"Fruit Flys stay busy!
I was given some fruit flys to keep and raise as part of a science experiment for an elementary school. They are not much to look at, they just look like little flies but the applications of using them are limited only by imagination. These are not very good "pet" pets or recommended for those who like cool looking pets. They just kind of fly around and breed. YOU DO NOT WANT TO DROP THE CONTAINER because they will eat even the smallest of food off walls, doors, etc. This happened to me and it took a month of setting out small dishes of soapy water with a candle in the middle until they were finally gone. NOT WORTH THE EFFORT.."
