The group of insects that undergoes complete metamorphosis is

The group of insects that undergoes complete metamorphosis is the one that includes houseflies, beetles, and butterflies. Complete metamorphosis is a process that involves four distinct stages: egg, larva, pupa, and adult. Insects that undergo complete metamorphosis have a larval stage that looks very different from the adult stage, and they go through a pupal stage during which they transform into the adult form. Houseflies, beetles, and butterflies all undergo complete metamorphosis. Housefly larvae are known as maggots, while beetle larvae are called grubs. Butterfly larvae are commonly known as caterpillars. These larvae look very different from their adult counterparts and go through a pupal stage before emerging as adults.
