Question

The silkworm larva ceases to eat and starts spinning silk around its body

• A. At random
• B. From inside to outside
• C. From outside to inside
• D. All of the above

Answer 1

The correct option is C From outside to inside

After the fourth and last moult of their skins, the silkworms will eat over half the food they will consume in their lifetimes. Once they reach a critical size they will empty their alimentary system completely in preparation for spinning their cocoon around the body from outside to inside.

Therefore, the correct answer is option C.
