Glaucina escaria
This record describes Glaucina escaria (species). Recorded family: Geometridae. Recorded order: Lepidoptera.
Identification and Appearance
Male forewings gray, heavily overlain with grayish brown or black; AM line weakly represented or absent; PM line complete but sometimes weakly represented, outwardly produced on veins with moderate concave loop approaching inner margin; ST line faintly indicated shaded basally by a slightly dark band; terminal area concolorous with remainder of wing; terminal line narrow, black or blackish brown; fringe slightly paler than wing, darkened opposite veins. Hindwing whitish gray, overlain with pale grayish brown scales, anal margin darker, small discal dot and incomplete extradiscal line present. Females similar to males, not as dark above with cross lines more prominent, hindwings with darkish band along outer margin. ( 3 ) membraneous invaginations extend transversely, at right angles to the ductus bursae. This is the type species for Glaucina .

Habitat and Range
Geographic Range
Southern Arizona. ( 3 ) In his review of the genus Grossbeck included material from the deserts of Arizona, Colorado, New Mexico, and California for Glaucina puellaria , now synonomyzed with escaria . Dr. Ed Knudson has confirmed sightings in Texas most often in the Rio Grande Valley, but occasionally in Uvalde Co. and in the Kerrville area.
Seasonal Activity
Adults fly March through October. ( 3 )
About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Glaucina escaria. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
