Complete Metamorphosis vs. Incomplete Metamorphosis — What's the Difference?
By Tayyaba Rehman — Published on December 15, 2023
Complete metamorphosis has four stages: egg, larva, pupa, and adult; incomplete metamorphosis has three: egg, nymph, and adult.

Key Differences
Complete Metamorphosis vs. Incomplete Metamorphosis: Complete metamorphosis involves a four-stage life cycle. In contrast, incomplete metamorphosis consists of only three stages without a pupal phase.
Complete Metamorphosis vs. Incomplete Metamorphosis: In complete metamorphosis, the larva looks and behaves differently from the adult. With incomplete metamorphosis, the nymph usually resembles a smaller version of the adult and matures gradually.
Complete Metamorphosis vs. Incomplete Metamorphosis: Butterflies and moths undergo complete metamorphosis, passing through a distinct pupal stage. In comparison, grasshoppers and crickets experience incomplete metamorphosis without a pupal stage.
Complete Metamorphosis vs. Incomplete Metamorphosis: The transformation from larva to adult in complete metamorphosis is drastic. In contrast, insects with incomplete metamorphosis show a more gradual change from nymph to adult.
Complete Metamorphosis vs. Incomplete Metamorphosis: In the realm of insects, complete metamorphosis is considered a more evolved trait. In contrast, incomplete metamorphosis represents an earlier stage in insect evolutionary development.

Common Curiosities
What is the main difference between larva and nymph?
Larva, found in complete metamorphosis, looks different from adults. Nymphs, in incomplete metamorphosis, resemble smaller adults.
What insects undergo complete metamorphosis?
Butterflies, moths, beetles, and flies are examples of insects that undergo complete metamorphosis.
Which metamorphic process is more evolutionarily advanced?
Complete metamorphosis is considered a more evolved trait in insects.
Are the insects active during all stages of incomplete metamorphosis?
Yes, insects are typically active during all stages of incomplete metamorphosis, unlike the pupal stage in complete metamorphosis.
Do all stages feed in incomplete metamorphosis?
Typically, yes. Unlike the pupal stage in complete metamorphosis, all stages in incomplete metamorphosis usually feed.
Can we say all insects undergo either complete or incomplete metamorphosis?
While many do, some primitive insects have even simpler life cycles without clear metamorphosis.
Is the nymph stage present in complete metamorphosis?
No, the nymph stage is characteristic of incomplete metamorphosis.
Are the changes in complete metamorphosis more drastic than incomplete?
Yes, the transformation in complete metamorphosis is more dramatic compared to the gradual change in incomplete metamorphosis.
Why don't we see the pupal stage in incomplete metamorphosis?
Incomplete metamorphosis has a more direct development without a resting or transformation phase like the pupa.
Which type of metamorphosis is found in cockroaches?
Cockroaches undergo incomplete metamorphosis.
Is the larval form in complete metamorphosis typically active?
Yes, larvae are usually active and feed voraciously to accumulate energy for the pupal stage.
How long can the pupal stage in complete metamorphosis last?
It varies among species and environmental conditions, ranging from days to months.
Which process, complete or incomplete metamorphosis, is more common among insects?
Complete metamorphosis is more common, with about 80% of insect species undergoing this process.
In which metamorphosis do we find a chrysalis or cocoon?
A chrysalis or cocoon is found in complete metamorphosis during the pupal stage.
Is incomplete metamorphosis a more primitive trait?
Yes, incomplete metamorphosis is considered an earlier evolutionary stage in insect development.
