Pandemis canadana

Small size (19–20 mm wingspan) distinguishes it from larger Pandemis species. Forewing pattern includes variable greenish or brownish ground color with darker transverse bands. Examination of genitalia may be required for definitive separation from congeners.

Small moth with wingspan 19–20 mm. Forewings are typically greenish or brownish with variable banding patterns characteristic of the genus.

Deciduous forests and shrublands. Associated with stands of aspen and other broad-leaved woody vegetation.

North America: British Columbia to Nova Scotia, south to Colorado, Illinois, and Maine. Additional records from Alberta, Manitoba, and Saskatchewan.

Adults active from early July to mid-August. Single generation per year inferred from flight period.

Larvae feed on various deciduous trees and shrubs. Specific host records beyond this general statement are not documented in available sources.

Larval herbivore in deciduous forest ecosystems. Population dynamics and specific ecological impacts have not been quantified.

Minor or negligible direct economic impact. Not documented as a significant pest of forestry or horticulture.

• Pandemis limitataOverlapping range and similar size; requires genital dissection or detailed wing pattern analysis for separation
• Pandemis pyrusanaSimilar appearance and habitat use; distinguished by subtle wing pattern differences and geographic distribution
