Xestia praevia
Lafontaine, 1998
Praevia Dart
Xestia praevia is a noctuid native to western North America, ranging from Canada to California. It belongs to the elimata group, within which genetic and morphological studies suggest it may not be distinguishable from Xestia elimata and Xestia badicollis. The species is associated with ponderosa pine forests, where its larvae feed on Pinus ponderosa. are active during mid-summer.
