Everything you need to know about black soldier fly larvae

The larvae are off-white, torpedo-shaped with a firm exoskeleton, and strong chewing mouthparts to shred and devour feeding substrate.

There are 6 instars in the larval stage, and passing through it all requires 13-18 days. We can refer to a larva as an adult if it grows to a size of 20 mm. As they reach the 6th instar, they turn dark brown and step into the prepupa phase. During their development, the larvae are greedy feeders; they can eat twice their body size a day, so it is crucial to always provide them with enough streams of fruits, vegetables, and grain for optimal production.

How to store the black soldier fly larvae properly?

Once your package arrives, place the larvae from the bag in a pot, crate, or container. When kept as a part of your insect colony, place the larvae in rearing crates and give them plenty of feed. When used within two weeks, keep them in a dry, cool place protected from sunlight. With prolonged storage, the larvae may pupate under favorable conditions, from which flies hatch within a few days. However, it can still be an ideal food for reptiles and other pets in this form.


The larvae stage can be maintained for one-two months if stored at 13-15 °C.

Feeding is not necessary, but they would consume any stream of fruit, vegetable, or grain.
