Maintaining annulimana group flies

Food requirements

We grow these on banana food. The larvae are large and can easily eat all the food in the vial -- you may consider adding extra food.


18 - 25°C is the range they will grow at. They grow slower at the lower temperatures. Embryo to adult will take about 20 days depending upon the temperature.

Pupation conditions

The addition of paper along the side of the vial when there are many larvae present is helpful. The larvae will also pupate in the plug of the vial no matter what the material is.

Special requirements

Adults require many days to reach sexual maturity, if you transfer adults to new vials immediately after they eclose you will not get eggs for over a week and the food can go bad. One solution is to combine older adults with newly-eclosed adults when you set up new vials/bottles.
