The lacewing is a delicate insect, and for most people it is a familiar sight. Lacewings are irresistibly attracted to artificial light, and they often fly in at open windows at night.

The female lacewing has a most extraordinary way of laying eggs. She first exhudes a drop of sticky liquid on the underside of a leaf, and then she raises her abdomen to draw it out into a hair-like stalk. This hardens immediately, and then she lays an egg at the end of this.

The larvae which hatch from the eggs laid by a lacewing have two long scimitar-shaped jaws. Since they are voracious feeders on greenflies, they are the good friends of gardeners.
