To regulate its body temperature, the dragonfly may either patrol, i.e. it flies back and forth and move its wings rapidly to warm up its body, or perch, i.e. it positions itself on structures and expose its body to the sun’s rays. I read that the dragonfly can use its wings as reflectors, tilting them to direct the solar radiation toward its body. However, during hot spells, the dragonfly will use its wings to deflect the sun rays away from its body.
