Summary: flight is prodigious, as many as twenty-two midges having been found in the stomach of a single individual. Dragon-flies are also useful as the destroyers of harmful insects, more especially mosquitoes, and they are therefore protected in some places to prevent the spread of malaria and other insect-borne diseases. The habits and life histories of Odonata, especially the larval instars and metamorphosis processes, are quite fascinating and provide valuable insights into their unique adaptations and behavior. The diversity of Odonata species, their distribution patterns, and ecological significance make them a subject of great interest and research in the field of entomology.
