Bombyx mori are social creatures which can locomote. Because of their role in sericulture, the adults of the species can no longer fly (Herbison-Evans 1997).

Can silkworm moths fly?

They clamber around, vibrate their wings rapidly, and mate, but they don't fly or attempt to escape from their container. During the adult phase of the life cycle, the silkworm moths do not eat or drink.

Do Bombyx mori have mouths?

Even if the mulberry silk moths (Bombyx mori) are allowed to emerge from their cocoons, without killing them by boiling the cocoons in water, the moths will live only for 5 to 10 days. Why? They neither have a mouth to eat with nor a proboscis (like a butterfly does) to suck nectar with!
