Nymphs and larvae are both immature stages of insects, but they have key differences.
Nymphs are typically similar to the adult insect, but smaller and wingless. They may also have different proportions or body parts than the adult. Nymphs typically live in the same environment as the adults and eat the same food. They undergo a series of molts as they grow, gradually developing wings and other adult features.
Larvae, on the other hand, are typically very different from the adult insect. They may have a completely different body shape and may not have any wings or adult features. Larvae typically live in a different environment than the adults and eat different food. They undergo complete metamorphosis, which means they go through a pupal stage before becoming adults.
| Feature | Nymph | Larva |
|---|---|---|
| Body shape | Similar to adult | Very different from adult |
| Wings | Wingless | May or may not have wings |
| Habitat | Same as adults | Different from adults |
| Food | Same as adults | Different from adults |
| Metamorphosis | Incomplete | Complete |
Examples of nymphs include grasshoppers, crickets, and cockroaches. Examples of larvae include caterpillars, maggots, and grubs.
