COLONIZING AND POPULATING HABITATS
Amongst the other insects, such as dragonflies, stick insects and grasshoppers, the transformation from larva to adult is much more gradual. The immature stages look quite like the adults. We call the immature stages of these insects nymphs.
Each time they moult they look a bit more like the adult. The last parts to develop are the wings and the reproductive organs. Not only do the nymphs look like the adults but they also tend to eat the same kind of food. The nymphs also have senses which are just as good as those of the adults.

This type of development is called incomplete metamorphosis because the change in shape of the animal is more gradual. The diagram below shows the life cycle of the grasshopper which develops in this way.
