Can Axolotls Eat Black Soldier Fly Larvae?

Can a Axolotl Eat Black Soldier Fly Larvae?

Yes with a caveat, and it is worth knowing before you buy a cup.

Black soldier fly larvae — also sold as phoenix worms — are roughly 40–50% protein by dry weight, and they carry about 9,340 mg/kg of calcium.

That calcium figure is the whole reason to use them. Superworms carry around 100 mg/kg; mealworms are similarly poor. BSFL are the one common feeder that delivers calcium naturally, without dusting — which removes the single most commonly botched step in reptile feeding.

How Many, and How Often

Rarely, and only from tongs.

Why BSFL Suit a Axolotl

BSFL are terrestrial and anything uneaten fouls the water. Axolotls do better on earthworms, which are closer to a complete food for them.

The Dusting Question

Most feeders need a calcium supplement dusted on before every meal, and it is the step keepers most often rush or skip. BSFL do not depend on it. The calcium is inside the animal rather than sitting on the outside where it can be groomed off, shaken loose, or simply forgotten.

That does not make supplementation pointless across a whole diet — vitamin D3 still matters, and other feeders still need dusting. It means this particular feeder is not one more chance to get it wrong.

What Else to Feed

Run them alongside earthworms as the staple. Variety still matters — no single feeder should be the whole diet, however good its numbers are.
