Do Silkworms Bite? (Are silkworms safe to touch?)

Silkworms, those fascinating creatures responsible for creating luxurious silk threads, have captured our imagination for centuries. But have you ever wondered if these tiny beings can bite? In this article, we will explore the world of silkworms, their behaviors, and whether or not they pose a biting threat to humans.

Do Silkworms Bite Humans?

The straightforward answer is no, silkworms do not bite humans. Unlike some other insects like mosquitoes or ants, silkworms are not equipped with biting or stinging mouthparts. They do have a mouth, but it’s designed for eating and chewing mulberry leaves, not for biting people.

So, if you come across a silkworm, you can rest easy knowing that it won’t harm you. In fact, these gentle creatures are often raised by humans for their silk-producing abilities.

Why Silkworms Don’t Bite?

Silkworms’ lack of biting behavior can be attributed to their biology and lifestyle:

1. Mouthparts

Silkworms possess mandibles, which are specially adapted for cutting and chewing plant material, primarily mulberry leaves. These mandibles are not suited for biting or harming other creatures. They simply don’t have the anatomical structures necessary for biting.

2. Non-predatory Nature

Silkworms are herbivores, which means their diet consists solely of plant matter. They have no interest in hunting or biting other animals. Their entire focus is on eating, growing, and eventually spinning their silk cocoons.

3. Domestication

Over thousands of years of domestication, silkworms have been selectively bred for traits that enhance silk production. Aggressive or biting behavior is not conducive to this purpose, so such traits have not been encouraged in silkworm populations.

Are There Any Exceptions?

While the vast majority of silkworms are harmless to humans, there can be exceptions. Sometimes, when a silkworm feels threatened or provoked, it may attempt to defend itself. This defense mechanism usually involves regurgitating a green, foul-smelling liquid. While this can be unpleasant, it’s not a bite and poses no physical harm.

Therefore, even in rare cases when silkworms exhibit defensive behavior, it’s not a biting action, and it’s not meant to cause harm to humans.


In the world of insects, silkworms stand out as peaceful and industrious creatures. They are essential for the production of the luxurious silk we cherish, and they play a vital role in the textile industry. However, one thing you can be sure of is that they won’t bite you. So, if you ever come across a silkworm, you can admire its fascinating journey from caterpillar to cocoon without any fear of being bitten.
