Lacewing. Coloured scanning electron micrograph (SEM) of a green or common lacewing (Chrysopa septempunctata). Lacewings are flying insects which are commonly found in houses, as they are attracted by lights. The large compound eyes (brown) on the head of this lacewing give it a wide field of vision, which helps in finding prey and avoiding predators. The antennae (between eyes) also have a sensory function. Lacewings are insects distinguished by their delicate, net- veined wings (not seen). They are most active at twilight, and prey largely on aphids, which they kill with their powerful jaws (lower centre). Magnification: x4 at 6x7cm size.
