Common green lacewing (Chrysoperla carnea) larva. Coloured scanning electron micrograph (SEM) of the body of a common green lacewing larva, showing the spiracles (airways, circular) that open onto its outer surface. Adult common green lacewings feed on pollen and honeydew, whereas their larvae are active predators of aphids and other small insects. The spiracles are the openings that lead to the larva's respiratory system. Magnification: x130, when printed 10 cm wide.
