Maintaining virilis group flies

Food requirements

We grow these flies on our standard cornmeal food.


18 - 22°C is the range they will grow at. They grow slower at the lower temperatures. Embryo to adult will take 18 days at 24°C temperature. It takes several days for adults to become reproductively mature, so there is a longer window of time to collect virgins. 

Pupation conditions

The flies will typically crawl up the sides of the vial in order to pupate.
