Moths (as an actual gameplay feature)

Moths are like the #1 bug of all time hands down factual, i would sell one of my legs to get them in mc. Some ideas for how they work:

1: A silk worm mob that spawns when an area is fully covered by leaf litter AND has a tree nearby, the silk worm will slowly grow and form a cocoon on a nearby tree, leaving it behind as they sprout into a moth. The cocoon can be dismantled for string, and the moth itself will occasionally drop string

2: a random spawning moth mob similar to bees. Can land on a black and leaves string on any surface it lands on/drops string on a timer when flying.

Moths are bee-sized but with a wider wingspan

I beg for moths, i BEGGGG for moths. even if they dont do anything i NEED a moth,,
