...Michael L. May ABSTRACT Anax junius is a large dragonfly that regulates thoracic temperature ( T th ) during flight. This species, like several other intermittently endothermic insects, achieves control of T th at least in part by increasing circulation of hemolymph to the abdomen at high air...

...Michael L. May ABSTRACT The large, endothermic dragonfly Anax junius regulates the temperatures of its thorax ( T th ) and head ( T h ) during flight. At high ambient temperature ( T a ) it is able to dispose of excess heat from the thorax by increasing hemolymph circulation to the abdomen...
