Insect wings as a solar cell system

This work demonstrated that most flying insect species use their wings pigment to absorb light and reemits this light as fluorescence. Four flying insects were used; dragonflies, Orthetrum brunneum; seven-spotted lady beetle, Coccinella septempunctata; white grubs, Pentodon bispinosus and sphingid moth, Acherontia styx. The results showed that the yellow and black pigments which in the lady beetle adults wings have many elements such as carbon, nitrogen, oxygen, potassium, phosphor, sulphur, chloride and calcium. Magnesium, phosphor, sulphur and calcium not found in the posterior wings (which known that a membranece). The dragon fly adult also has a yellow pigment in all anterior and posterior wings. The results showed that the yellow pigment has silicon in yellow pigment except in central veins of wings. Carbon, nitrogen, oxygen, potassium, sodium and chloride were found in white grub adult wings. The adult of sphingid moth (which have yellow and black pigment in anterior and posterior wings) has silicon, aluminum and chloride which known as the main component in solar cell system. These elements were found in the yellow pigment in the anterior wings. Silicon and chloride not found in the black pigment in the adult wings. Data cleared that the flying insects use the color in their wings as a solar system to generate the power. This mechanism can be used as an alternative source of energy in nature.
