Moths of this genus are variously called "long-horned moths" or "fairy moths." I am not familiar with the caterpillars, which are supposed to feed upon leaf fragments on the ground, but the adults of this species invariably come to the naturalist's attention in the spring because of their extremely long antennae. The adults are especially attracted to the flowers of the Ox-eye Daisy Leucanthemum vulgare , on which they can be seen in the spring in some numbers.
