Can Fire-Bellied Toads Eat Silkworms?

Can a Fire-Bellied Toad Eat Silkworms?

Yes — silkworms are one of the better feeders you can offer a fire-bellied toad, and they can be a regular part of the diet rather than a treat.

Silkworms (Bombyx mori) are one of the few feeders that are genuinely good rather than merely convenient: roughly 64% protein and only 10% fat by dry weight, over 80% moisture, and a calcium-to-phosphorus ratio of about 1:1. Most feeder insects are badly inverted on that last one and need dusting to correct it. Silkworms mostly do not.

They are also soft-bodied and highly digestible, which matters for a young animal, a recovering one, or anything that struggles with hard-shelled prey.

How Many, and How Often

1–2 small silkworms twice a week.

Why Silkworms Suit a Fire-Bellied Toad

Small silkworms suit a small toad, and being soft-bodied they are easier to swallow than a hard-shelled feeder of the same length.

What Else to Feed

Silkworms are excellent but they have no real exoskeleton, and a diet of nothing but soft prey leaves the gut underworked. Run them alongside small discoid roaches and crickets rather than instead of them.

One Thing That Kills More Silkworms Than Anything Else

Never refrigerate them. Cold is the single most common cause of a whole cup dying at once. Silkworms are not crickets or waxworms — they want room temperature, and putting them in the fridge to "keep them fresh" is what kills them.
