Drosophila melanogaster
A tiny 2-3mm fly with a yellowish body and red eyes. Flightless strains with underdeveloped wings are cultured in tubs as a micro live food for young mantis nymphs and small frogs.
Drosophila melanogaster Meigen, 1830 is a fly of the family Drosophilidae about 2-3mm long, with a yellowish body and red compound eyes. It is thought to originate in central Africa and has spread to warm regions worldwide; in Japan it is common around kitchens and stored food. In the wild it feeds on ripe fruit and sap and the yeasts growing on them. Its small size, short life cycle, high fecundity and simple diet made it a classic model organism, especially in genetics. Under laboratory conditions a generation takes about 10 days at 25C, adults live about two months and a female lays around 50 eggs a day. For feeding, flightless strains with a wing mutation are used, as is the larger Drosophila hydei. Adults are placed on a medium made from instant mashed potato and similar ingredients; kept at 20-30C, a new generation emerges roughly every two weeks at about 25C. In Japan ready-made cultures are sold at specialist shops for first-instar mantises and small frogs.

Yeast (fermenting medium, ripe fruit)
Keep at 20-30C and never below 15C. Development speeds up with warmth; at about 25C the next generation of adults appears roughly two weeks after the parents go in.
Use lidded 300-600ml tubs with a hole in the lid covered by tissue, which lets air in but keeps flies in. Add plastic or wood strips on top of the medium as perches; as fermentation softens the medium, flies drown without them.
A medium can be made from beer and instant mashed potato powder with vinegar and a little dried yeast. Laboratories use yeast, cornmeal and sucrose set with agar. Adding fruit or sugar tends to make cultures smell.
Tap 15-30 adults into a fresh tub and larvae appear in the medium within days. At 25C development runs about 1 day as an egg, 4 as a larva and 5 as a pupa. Start a new tub every one to two weeks and keep several going so the supply never breaks.
Adults live about two months. The medium dries and runs out in one to two weeks; if the flies will not be fed off soon, add a little fresh medium to keep them alive longer.
Keep lids tight so none escape. Seal spent medium and surplus flies before disposal and never dump them outdoors. A medium that is too wet or grows mould will smell, so retire that tub early.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Common fruit fly is 20〜30℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Common fruit fly is Adults about 2 months (laboratory conditions). With proper care and nutrition, they can live a long and healthy life.
Common fruit fly typically reaches 2-3mm long as an adult. Size may vary depending on care conditions and individual genetics.
Common fruit fly feeds on: Yeast (fermenting medium, ripe fruit). Aim for a balanced diet with appropriate feeding frequency.
