Givira lucretia

Differs from the related white-winged Givira delindae (described from White Sands, New Mexico) by geographic range and presumably by wing pattern; G. lucretia has a darker, more typical cossid appearance compared to the pale, nearly unmarked wings of G. delindae. Separation from other small North American Hypoptinae requires examination of genitalic morphology.

Small moth with wingspan 23–28 mm. Specific coloration and pattern details not documented in available sources.

Arid and semi-arid environments. Recorded from gypsum dune systems and adjacent desert scrub in Wyoming, Texas, and Arizona.

United States: Arizona, Texas, and Wyoming.

Adults active April through August; multivoltine or with extended emergence period.

• Givira delindaeAlso a small white-winged Givira from the southwestern US, but G. delindae is nearly pure white with satiny wings and restricted to White Sands, New Mexico; G. lucretia has darker coloration and broader distribution.
• Other Givira speciesMost North American relatives are dark-colored or have substantial dark smudges on forewings; four species including G. lucretia are substantially white with few or no dark markings.
