Husbandry Information for D. straubae

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.


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

D. straubae are subject to a mold infestation. The best strategy is to subject the adults to rapid transfer to new food every 24 hours for a few days.
