Maintaining obscura group flies

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. Some species in this group will do fine on standard cornmeal food, especially if it is a nutritious recipe.


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

Pupation conditions

The flies will typically crawl up the sides of the vial in order to pupate. The addition of paper helps if you are trying to expand the stock.
