What is the scientific name of the lepidopteran domesticated for silk production?

• A. Bombyx mori
• B. Atta cephalotes
• C. Danaus plexippus
• D. Bombyx mandarina

Answer: (A)

The important idea here is to recognize the species that has been specifically domesticated for silk production. Silk comes from the caterpillar stage of the domesticated silkworm, whose scientific name is Bombyx mori. This species has been bred for producing long, strong silk fibers and for thriving in controlled rearing conditions, which is why it’s the primary source of commercial silk. Bombyx mandarina is a wild ancestor closely related to the domesticated form, not the widely farmed one. The other two options are an ant and a monarch butterfly, neither of which are used for silk. So Bombyx mori is the correct name.
