Although total harvests of silk were down in 2016, the mean acquisition price for the industry rose by . The silkworm is one of the few organisms wherein the principles of genetics and breeding were applied to harvest maximum output[citation needed]. Various arthropods, e.g. The larvae then prepare to enter the pupal phase of their lifecycle, and enclose themselves in a cocoon made up of raw silk produced by the salivary glands. Some may emerge with the ability to lift off and stay airborne, but sustained flight cannot be achieved. The median ocelli develop from a transverse fold of the ectoderm. The domestic species B. mori, compared to the wild species (e.g., B. mandarina), has increased cocoon size, body size, growth rate, and efficiency of its digestion. While other Lepidoptera produce cocoons, only a few large Bombycidae and Saturniidae have been exploited for fabric production. Dab at the sweat stain.
