Catocala luciana

Strecker, 1874

Shining Underwing, Luciana Underwing Moth

Catocala luciana is a medium-sized underwing in the Erebidae, first described by Herman Strecker in 1874. The is native to western North America, with a distribution spanning the Great Plains from southern Canada to the southwestern United States. Like other members of the Catocala, it possesses cryptic forewings that conceal brightly patterned hindwings, a characteristic defensive . are active in late summer and early autumn.

These audio files are automatically generated. While they are not always 100% accurate, they are a good starting point.

Identification

Distinguished from other Catocala by geographic range and . Within its range, identification relies on examination of forewing pattern details and hindwing coloration. Accurate identification typically requires reference to specialized keys for the Catocala and comparison with confirmed specimens. The species name 'luciana' (meaning 'shining') presumably refers to hindwing appearance, though this is not explicitly documented.

Images

Appearance

Wingspan 63–68 mm. Forewings are cryptic, typically gray-brown with mottled patterning that provides camouflage against tree bark. Hindwings are concealed at rest; when exposed, they display the bold coloration characteristic of underwing moths. Specific hindwing pattern details for this are not well documented in available sources.

Habitat

Associated with wooded and semi-wooded across the Great Plains and western North America. Specific plant requirements for larvae have not been documented in available sources. Occurs in areas supporting the tree required for larval development, though these remain unspecified.

Distribution

Western North America, extending eastward to Minnesota and Illinois. Northern limit in extreme southern Alberta and Saskatchewan, Canada. Southern distribution includes New Mexico, Arizona, and California. Widespread across the Great Plains region.

Seasonality

on wing from August to October, with exact timing varying by location within the range.

Behavior

are and attracted to artificial light sources. Like other Catocala , exhibits a startle display : when disturbed, the exposes its brightly colored hindwings to momentarily startle potential before taking . This behavior has been observed in the but not specifically documented for C. luciana.

Ecological Role

Larval stage presumably functions as a folivore on woody plants, though specific associations are undocumented. may contribute to pollination as visitors to flowers, though this has not been studied. Serves as prey for nocturnal including bats, birds, and arthropods.

Human Relevance

Subject of interest to lepidopterists and enthusiasts, particularly during National Moth Week events. The contributes to citizen science datasets through observation platforms such as iNaturalist. No documented economic importance or pest status.

Taxonomic Note

The specific epithet 'luciana' has been interpreted as 'shining' or 'light-bearing,' likely in reference to the hindwing appearance. The 'Shining Underwing' reflects this etymology.

Observation History

As of available records, iNaturalist documents 15 observations of this , indicating it is encountered infrequently relative to more common Catocala species. This may reflect true rarity, cryptic habits, or under-sampling of appropriate .
