It has two pairs of scaly wings, and a pair of segmented antennae. It still has the three part body (head/thorax/abdomen), 3 pairs of jointed legs, compound eyes, and a segmented exoskeleton N1:The pupa stage in a butterfly’s life is when the larva is encased in a chrysalis and undergoes metamorphosis.
