What do Green silkworms turn into?

How many hearts does an inchworm have?
These 10 individual “hearts” or aortic arches line the central body cavity and their mechanical pumping action facilitates the circulation of the earthworm, much like a human heart does.
Do all caterpillars turn into butterfly?

Do caterpillars have brains?
The brain and nervous system of caterpillars is dramatically reorganized during the pupal stage and it has not been clear whether memory could survive such drastic changes. The findings of the Georgetown researchers suggest the retention of memory is dependent on the maturity of the developing caterpillars’ brains.
