Calophasia lunula is a species of noctuid moth known by the common names toadflax moth and toadflax brocade moth. It is used as an agent of biological pest control against yellow toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria genistifolia ssp. dalmatica) in areas where they are considered noxious weeds, such as in North America.

The adult is a hairy gray moth about 12 millimeters long. The female lays anywhere from 30 to 80 eggs on the leaves and flowers of toadflax plants. In one to two weeks the larva emerges from the egg and begins feeding. This caterpillar undergoes five molts during a one-month period. The first-stage larva is about 5 millimeters long and dark gray in color. The eyecatching older larvae are black and white spotted with bright yellow stripes. The mature larva is about 4 centimeters long. After this stage it pupates through the winter in a cocoon of chewed plant matter and leaf litter.

Damage to the plants is done by the voracious feeding of the caterpillars. They consume all the new leaf and flower buds first and then move on to eat stems, leaves, and flowers, often to the point of complete defoliation of large numbers of toadflax plants. This does not necessarily kill the plants but it severely reduces their ability to produce seeds and propagate. Adults feed harmlessly on the plants' nectar and do not contribute to the damage.

This moth is native to Europe. It was first introduced to Canada as a biocontrol agent in the early 1960s, and to the United States shortly thereafter. The moth is now established in many areas. It tends not to establish as easily in colder climates.
