Introduction

Natural biomaterials have many optimized structures and functions adapted to their living surroundings through the evolution over millions of years. Based on the structures of biomaterials, some biomimetic materials, including nano-composite materials, have been developed [1]. There are more than one million species of insects in nature. Insects are important biological resource for developing biomimetic techniques [2]. Dragonfly can hover, flap its wings for flight and accelerate [3]. The mass of the wings of a dragonfly is only 1–2% of its whole body mass, but the wings can stabilize their body and have a high load-bearing ability during flight [4].

Living dragonflies, Anax parthenope julius Brauer (Odonata, Anisoptera, Aeschnidae, Anax) were collected in Chuangchun, China. Figure  1 shows the digital camera photograph of a female dragonfly Anax parthenope juliusBrauer. The body length of the dragonflies used for tests is about 68 mm. The wing span of the forewings and...
