The larval stage of a mosquito is called a wriggler. When a mosquito lays its eggs in water, they hatch into wrigglers, which are aquatic larvae. Wrigglers live in the water and breathe through a snorkel-like structure called a siphon. They feed on small organisms in the water and grow rapidly, molting several times as they increase in size.
After several days or weeks, depending on the species and environmental conditions, the wrigglers pupate and transform into adult mosquitoes. During the pupal stage, the mosquito undergoes a dramatic metamorphosis, developing wings and other structures that are not present in the larval stage. Finally, the adult mosquito emerges from the pupa and flies away in search of a blood meal.
In contrast, grubs are the larvae of beetles, maggots are the larvae of flies, and caterpillars are the larvae of butterflies and moths. While these larvae share some similarities with mosquito wrigglers, they have different body shapes and behaviors, and they do not go through the same developmental stages.
