Bombyx mori, commonly known as the domestic silk moth, is a moth species belonging to the family Bombycidae. It is the closest relative of Bombyx mandarina, the wild silk moth. Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk.
Conceivably, today's domestic silk moths are all descended from an initial stock of B. mandarina collected as far back as 5,000 years ago. [1] While wild silk could have been collected and used as threads, etc., since much earlier, the technology to breed and use silkworms from a domesticated stock did not exist before the late Neolithic .

Unlike most silk moths, those that pupate underground do not use much silk in the construction. [2] Once enclosed in the cocoon, the caterpillar sheds the larval skin and becomes a pupa, and the pupa undergoes metamorphosis for about 14 days, at which point it either emerges or goes into diapause.
Rosy maple moths are the smallest of the silk moths. The rosy maple moth is the smallest of the silk moths; males have a wingspan of 3.2 to 4.4 centimetres (1.25-1.75 in); females of 3.8 to 5 centimetres (1.5–2 in).

The polarization of the Sun's light changes with the angle of the rays, hence they can also navigate with cloudy weather. There are indications that they can even make corrections depending on the time on a day. Diamondback moths are known to fly in a straight trajectory which is not dependent on the angle of the Sun's rays. [14]
