There are four stages in a complete metamorphosis and three in an incomplete one. Hope this helped.
what chrysalis forms in what stage of metamorphosis
No it does not because the first stage of a complete metamorphosis is an egg
When an insect has gone through metamorphosis, it has completely changed its form. If it had a pupal stage before metamorphosis, then it underwent complete metamorphosis. If it didn't have a pupal stage, then it underwent incomplete metamorphosis.
Yes, they have an incomplete metamorphosis because they don't have a larval stage, they have a nymph stage.
This stage is known as imago. It is the final stage in the process of metamorphosis, and is when the insect gains adult maturity.
