When a larva has eaten enough food and grows big enough, it pupates into the third body form, the pupa. While in this form, the beetle does not eat or move very much. The pupa just sits and waits while its insides rearrange into the form needed for the fourth and final body stage.
Beetles, like other insects, go through a complete process of metamorphosis in which it goes through four stages of development. (Some female beetles keep their eggs inside of them and give birth to live larvae). It usually takes from 4 – 19 days for the eggs to hatch. They then enter into the larval stage.
Where do beetles pupate?
The larvae of ambrosia beetles feed on fungus gardens cultivated by adults in the sapwood of trees. Following the larval stage, the beetle enters the pupal stage. The pupa develops beneath the skin of the final larval stage, then emerges when the skin splits. The pupa is a soft, pale image of the adult it is to become.
How does a beetle transform?
Beetles, like all insects and other arthropods, go through distinct changes in form throughout their life cycle. This change in form is known as metamorphosis. You may recall other examples of life changes from your biology classes such as the caterpillar changing to the butterfly or a tadpole maturing into a frog.
What do little beetles eat?
What Do Beetles Eat? They feed on plants, small insects and animal fibers, depending on species. A few beetles are considered pests in gardens and crops, although some species may benefit humans by killing harmful insects. Adults often deposit their eggs near the food that the larvae will eat when they hatch.
