توضیح
Blackflies, houseflies, and mosquitos undergo complete metamorphosis, meaning they go through distinct stages of egg, larva, pupa, and adult in their life cycle. This type of life cycle involves a distinct pupal stage where the organism significantly changes its form before emerging as an adult. E.g Insects like butterflies, beetles, bees, ants, and most flies, including houseflies and mosquitos, all exhibit complete metamorphosis.
