The larvae of the genus Zale, unlike typical phalaenid larvae, are long and slender, and taper anteriorly and posterioriy. The anterior pairs of abdominal prolegs are reduced in size, and the anal prolegs are usually extended behind the body. The species are closely related to those of the genus Cntocala, with which they should not be confused.
The nomenclature of the conifer-feeding species is that used by McDunnough (1943) in his revision of the obliqua-metatata group, and the species lineosa (Walker) is the species to which Morrison's names galbanata and penna are referable (Franklemont, 1950).
