Caterpillars don't "morph" into butterflies. Their bodies turn into a protein 'goop' within their chrysalis and rapid DNA-driven cell-division takes care of the rest

Locusts are not a type of animal, it is a condition experienced by some grasshoppers when they are overcrowded (triggered by legs and arms rubbing together). Once they transform, they grow larger and change colour.

A queen bee is created by a few randomly selected larva (irrespective of gender) being fed Royal Jelly to make them develop queen morphology

Salmon change color to attract a spawning mate
