Glaucina baea
Rindge, 1959
Glaucina baea is a of geometrid in the Ennominae, described by Rindge in 1959. It belongs to a of small to medium-sized moths characterized by relatively plain, grayish or brownish forewings. The species is known from North America, though specific details about its remain poorly documented. It is one of approximately 20 described species in the genus Glaucina, most of which occur in western North America.

Identification
Members of Glaucina can be distinguished from similar geometrid by their relatively unmarked, somewhat triangular forewings with smooth outer margins and reduced pattern elements. Within the genus, identification generally requires examination of genitalic structures. Glaucina baea was described from California and may be separable from by subtle differences in wing shape and the degree of grayish suffusion on the forewings, though published diagnostic characters are limited.
Distribution
Known from North America; the type locality is in California, USA. Records suggest a western North American distribution consistent with other members of the .
Similar Taxa
- Glaucina errorariaOverlaps in distribution and shares similar plain grayish forewing coloration; distinguished by more pronounced discal spot and slightly more angular wing apex.
- Glaucina lowensisSimilar size and ground color; G. baea may differ in having less contrasting wing markings and more uniform gray tone.
- Iridopsis speciesAnother geometrid with plain gray ; Iridopsis typically shows more pronounced wavy transverse lines and a more pointed forewing apex.

Taxonomic note
The Glaucina was revised by Rindge (1959), who described G. baea based on material from California. The specific epithet 'baea' is of unclear derivation. No subsequent taxonomic treatments have focused specifically on this .
