Bombix Mori

The silkworm larva hatches from a small black egg and eats mulberry leaves constantly for 4 to 6 weeks as it grows. It molts its skin multiple times during this period. Then, the caterpillar spins a cocoon made of silk to pupate in for about 3 weeks. An adult moth then emerges but cannot fly and only lives for around 5 days to reproduce before dying. The lifecycle shows the progression from egg to various larval stages to pupation in a cocoon and then to the short-lived adult moths.

Larva de Bombix Mori

Lifecycle:

The tiny Silkworm larva hatches from a tiny black egg. The larva eats mulberry (Morus alba) leaves almost constantly for 4 to 6 weeks until it is 2 3/4 inches long. The white caterpillar molts its skin many times during this stage. The caterpillar then pupates; it spins a white silk cocoon around itself (in a process taking 3 or more days). The silk cover s a hard brown-shelled pupa. In roughly three weeks, the adult moth emerges. This white moth cannot fly; it reproduces and dies within about five days (the female lays from 200 to 500 lemon-yellow eggs that eventually turn black). Classification: Class Insecta (insects), Order Lepidoptera (butterflies and moths), Suborder Ditrysia (Moths, Butterflies, Skippers), Superfamily Bombycoidea, Family Bombycidae, Genus Bombyx, Species B. mori.
