We have separated the worms from the Pupae that are starting to pupate into flys. These Pupae are darker in color and become less active as they get further into the cycle. These darker worms actually have higher levels of calcium and we strongly suggest feeding these off to your animals if they will go after slower moving bugs! These Pupae have 1-2 weeks till they turn into flys! If the conditions are good enough the black soldier flys will emerge and are still great to feed to your reptiles! Most animals actually love to chase the flys and eat them. They are a good enrichment activity and still a good feeder for your reptile!
