Maintaining repleta: hydei subgroup 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.

Temperature

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 species and the temperature.

Pupation conditions

The addition of paper along the side of the vial when there are many larvae present is often necessary.

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. One solution is to combine old and new vials when you transfer.
