Heat-distribution in the body and wings of the morpho dragonfly <i>Zenithoptera lanei</i> (Anisoptera: Libellulidae) and a possible mechanism of thermoregulation

Abstract Animals that live in hot environments must deal with extreme temperatures and overcome the constraints imposed by overheating. Some species exhibit remarkable adaptations to control body temperature, usually form of structures act as thermal windows cool down dissipating heat. Here, we describe case dragonfly Zenithoptera lanei, which inhabits open areas Neotropical Savannah Amazon. Males have striking unique on wings, not known any other insect. The wings are covered wax nanocrystals reflect ultraviolet light infrared radiation. Furthermore, wing membrane is permeated an intricate system tracheae, another trait Insecta. We hypothesized these might be important only for intraspecific communication, but also thermoregulation. analysed male compared them common translucent wings. results suggest dorsal surface acts a cooling system, whereas ventral serve elevate temperature. Therefore, conclude Z. lanei possesses nature; complex thermoregulation dual function or elevating depending position.
