Question types: Insect metamorphosis
Rule: Insects
Complete metamorphosis: egg → larva → pupa → adult (butterfly, beetle, bee, fly).
Incomplete metamorphosis has no pupa: egg → nymph → adult (grasshopper, dragonfly, cockroach).
Example: A caterpillar is the larva of a butterfly; between them comes the pupa.
Watch out: A dragonfly nymph lives in water and never makes a pupa: dragonflies have incomplete metamorphosis.
