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 Large will contain at least 250 soldier fly larvae ready to feed out as soon as they arrive. Large Black Soldier Fly Larvae measure approximately 1/2-3/4", 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 55-65°F 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!

My Veiled LOVES both worms and flies

I think I'm switching my chameleon's food to BSFL because he loves both the worms and flies. AND my Josh's Frogs orders always arrive alive.

Geckos like them.

My crested and leopard gecko babies really like these. They especially like how they wiggle in the food dish and are easy to catch and for practice hunting for the babies. Even the clumsiest geckos can catch them. They also live just fine in their packaging and arrived perfectly fine with no deaths that I could find. They last a pretty long time but some did hatch out in the 3 weeks I had them. Their probably the least maintenance feeder I have tried. (versus crickets and mealworms)
