It’s true that not all insects have a pupal stage. Some examples of insects with simple metamorphosis (and without a pupal stage) are cockroaches, crickets, and bed bugs. In these groups, the newly hatched insect is usually called a nymph and it looks like a miniature form of the adult insect that it will become.

Developmental stages

• Egg.
• Larva.
• Pupa.
• Imago.

There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.

In ametabolous insects, the immatures are called young. In hemimetabolous insects, the immatures are called nymphs. (A naiad is an aquatic nymph.) In holometabolous insects, the immatures are called larvae and pupae….Examples:

Satyr is the male equivalent of the nymph.

In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph’s overall form already resembles that of the adult, except for a lack of wings (in winged species).

Nymphs are commonly found under or on rocks, in aquatic vegetation, fallen tree branches in the water, and even in gravel, sand, or loose sediment. They do not have wings nor can they fly in this insect stage.
