Zygoptera is a scientific name for a group of insects commonly known as damselflies. Synonyms for this word include suborder Zygoptera, infraorder Zygoptera, and order Odonata. These synonyms are used interchangeably to refer to the same group of insects. Damselflies are characterized by their slender bodies, long wings, and compound eyes. They can be found in a wide range of habitats, including ponds, lakes, rivers, and wetland areas. Damselflies are important predators in their ecosystems, feeding on other insects including mosquitoes and flies. They are also used as indicators of water quality, as their presence or absence can indicate the health of aquatic ecosystems.
