Husbandry Information for D. subobscura

Food requirements

We grow these flies on banana Opuntia food. You can prepare the banana-malt food without the cactus powder, because the Opuntia powder is merely a consequence of how our kitchen prepares the food.


18 - 20°C is the range they will grow at. D. subobscura prefer cooler temperatures. They do very well at 18°C. Embryo to adult will take 20-24 days depending upon the temperature.

Pupation conditions

The flies will typically crawl up the sides of the vial in order to pupate, but the addition of paper along the side of the vial when there are many larvae present is helpful.

Special requirements

The females only mate once, this is important because if they do not get enough sperm from one mating they will lay unfertilized eggs.
