摘要
The surfaces of the veins of dragonflies(Pantala flavesens Fabricius and Crocothemis servilia Drury) wings are observed through SEM,and interesting micro and nano structures and morphologies are discovered.On the surfaces of the veins,not only ripple wave morphologies are distributed,but also spikes are grown.Besides,on the surfaces of the spikes,straight stripe wave morphologies are grown along the generatrix.These marvelous micro and nano structures and morphologies may enable us to better understand the remarkable flying abilities of dragonflies.
The surfaces of the veins of dragonflies (Pantalaflavesens Fabricius and Crocothemis servilia Drury) wings are observed through SEM, and interesting micro and nano structures and morphologies are discovered. On the surfaces of the veins, not only ripple wave morphologies are distributed, but also spikes are grown. Besides, on the surfaces of the spikes, straight stripe wave morphologies are grown along the generatrix. These marvelous micro and nano structures and morphologies may enable us to better understand the remarkable flying abilities of dragonflies.
