About This Product

LIVE ARRIVAL GUARANTEED if your temps fall within our LAG (read here). Please check your temps before ordering!

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 - 50 count Medium will contain at least 50 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!

Our Toads Love Them

These larvae are easy to feed, and our toads love them. They arrived safely and lived for a long time.



Love the cost and fast shipment


Very Impressed!

My very first purchase from Josh's Frogs! I was very impressed with how fast my order shipped and was received. Very well packaged and very affordable (including shipping), as well. The BSFL were the perfect size for my jumping spider. All arrived alive and active. Great quality. Great company. Great service. I'll definitely be a returning customer.


My Day Geckos loved these!

My Day Geckos went right after the soldier flies and really seemed to enjoy them.
