Cicadas, froghoppers, and pond skaters belong to the class Insecta, characterized by their three-part body structure (head, thorax, and abdomen), jointed legs, and exoskeleton made of chitin. They exhibit distinct life cycles, often involving metamorphosis, and play significant ecological roles such as pollinators and part of aquatic and terrestrial food webs. Understanding their classification and biological traits is essential in the context of biodiversity studies and ecosystem management, relevant topics in the UPSC syllabus on environmental ecology.
