Can Tokay Geckos Eat Silkworms?

Can a Tokay Gecko Eat Silkworms?

Yes — silkworms are one of the better feeders you can offer a tokay gecko, 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

3–4 silkworms twice a week.

Why Silkworms Suit a Tokay Gecko

Tokays are large, muscular geckos and silkworms are among the highest-protein feeders available at roughly 64% by dry weight. Good for growth without the fat that comes with most rich feeders.

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 discoid roaches 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.
