Xylenine sallows is an unconventional grouping of fourteen genera of moths in the Tribe Xylenini of the subfamily Noctuinae. The term is not commonly used but is adopted here following Peterson Field Guide to Moths of Eastern North America. Xylenine sallows inhabit woodlands and old fields. They are active at night and will come to lights, sometimes in large numbers.

Eupsilia, a genus of xylenine sallows, occurs in Europe, western Asia, and North America. In the United States it is most common east of the Great Plains and in the Pacific Northwest.


There are at least 24 species of Eupsilia worldwide, 8 species in North America north of Mexico, and 4 species in Minnesota.

Xylenine sallows rest with their wings held flat. They overwinter as adults and fly for a short time in the spring. They are active at night and will come to light.


Xylenine sallows are thick-bodied owlet moths. Adults are to 1316 (17 to 21 mm) in length. The forewings are squared off on the outer margin. Caterpillars are up to 1 (3.5 cm) long.

Identifying both adults and caterpillars is difficult. Sometimes adults have to be identified by examining the scales under a microscope, or by examining the male genitalia, also under a microscope. Late instar caterpillars lose much of their distinctive coloration. They are best identified by rearing them to adults.
