Bryolymnia semifascia, known as the half-banded bryolymnia, is a small noctuid native to the southwestern United States.

Identification
Distinguished from by the partial (half) transverse band on the forewing, rather than a complete band. The combination of small size (26–29 mm wingspan), southwestern U.S. distribution, and conifer forest helps separate it from similar Bryolymnia . Examination of genitalia may be required for definitive identification; see Lafontaine et al. (2010) for technical .
