Moths, cocoons and caterpillars

Silk moths would be a new type of flying insect; they would begin as silkworm caterpillars.  After a while, they would climb trees and transform into cocoons that could be collected like blocks. They would have color variations for each biome variant, and after a few in-game days, they emerge and become moths. They can be attracted by bright lights and torches. They become mesmerized flying around luminous blocks. Each biome would have its own variant, some more beautiful with vibrant colors and others more earthy in color. The cocoon could be collected for decoration with a silken touch Enchantment , and breaking it open with your hand would release a lot of thread. The caterpillars could be attracted to leaves, and feeding on them would accelerate the process of transforming into cocoons. Mobs, such as some animals, might want to destroy the cocoon, so... The moth would build its cocoon high up in the tree trunks.
