This family includes moths with spindle-shaped bodies^ and narrow, strong wings, some of the species resembling Hawk-moths quite closely in this respect. The larvae are wood-borers, living in the solid wood of the trunks of trees. They are often very injurious to forest or shade trees, and one recently imported species is very injurious to pear trees. The wood-boring habits of the larvae suggest the popular name Carpenter-moths for the insects of this family. These moths fly by night, and lay their eggs on the bark.
