Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
Common green darners migrate in fall and spring but for several reasons the southward movement in fall is more noticeable. [ 15 ] By attaching micro-radio transmitters to common green darners, researchers have found them to be capable of migrating up to 140 kilometres (87 mi) in a day, though they typically cover less distance per day.
Dragonflies are among the longest distance insect migrants. Many species of Libellula, Sympetrum and Pantala are known for their mass migration. [2] Pantala flavescens is thought to make the longest ocean crossings among insects, flying between India and Africa on their migrations. Their movements are often assisted by winds. [25] [26]
