Description : Mosquito larvae, commonly known as ''wrigglers,'' are aquatic and characterized by a large head, a broad thorax, and a narrow, wormlike abdomen. They typically hang just below the water's surface, breathing air through tubes located at the end of their abdomen. The nutrients acquired during the larval stage are crucial for the mosquito's development into an adult. Larvae possess a specialized organ called a siphon, which they use to breathe air at the water's surface. They feed on organic matter found in standing water, such as that in unused fountains, buckets, paint cans, and rain barrels. Tehatta, West Bengal, India.
