About This Product

Black Soldier Fly (Hermetia illucens) larvae are a great feeder for a wide variety of reptiles, amphibians, birds, and invertebrates. High in calcium, black soldier fly larvae are also known in the trade as Phoenix Worms, ReptiWorms, and CalciWorms. Each container of Black Soldier Fly Larvae - 250 count Medium will contain at least 250 soldier fly larvae ready to feed out as soon as they arrive. Medium Black Soldier Fly Larvae measure approximately 1/4" - 1/2", and make perfect feeders for bearded dragons, chameleons, leopard geckos, fat tail geckos, and many insectivorous invertebrates.

How to Feed: Feed soldier fly larvae with tongs, or in a dish. Be careful not to allow solder fly larvae to escape the dish - the larvae will burrow and pupate into adult flies. After they pupate, the larvae emerge as adult black soldier flies, which resemble small wasps. Even though they look intimidating, black soldier flies are harmless. Once the worms began to pupate (if they're not eaten by them), they'll turn black. At this stage, the larvae contain a LOT of calcium, and should be quickly fed to your pets.

How to Store: Soldier Fly Larvae can be kept at room temperature, but keeping them at 55-65F will keep them in the larval stage much longer. Remember, black soldier fly larvae can still be fed out after they pupate. Adult flies can also be fed out - chameleons in particular seem to love these!

Reviewed on May 16, 2026.

These are lively little guys. Some are smaller than I expected, but that seems to be the norm for BSFL no matter where I get them. I'll order again from Josh's frogs because I like how active these are.

Chameleon Loves These!

Easy feeders/keepers, my veiled loves them even more when they turn into flies and can hunt them around her enclosure.
