Can Corn Snakes Eat Superworms?

Can a Corn Snake Eat Superworms?

No — superworms are not appropriate for a corn snake.

Superworms (Zophobas morio) are roughly 20% protein and 18% fat, and they reach about two inches — considerably larger than a mealworm. That size and that fat content are why animals love them.

The number that decides how they should be used is calcium. Superworms carry around 100 mg/kg of calcium. Black soldier fly larvae carry about 9,340 mg/kg — roughly ninety times more. A superworm is a rich, filling feeder that supplies almost no calcium at all, which is why dusting is not a refinement here. It is the whole point.

How Many, and How Often

None — corn snakes eat whole prey.

The Risk That Matters for a Corn Snake

Corn snakes are rodent feeders from hatchling size. Insects are not part of the diet at any stage.

What to Feed Instead

The staple should be appropriately-sized frozen-thawed rodents. Superworms are a supplement to a diet, not the diet.
