Catocala marmorata

Distinguished from other Catocala species by geographic range and association with Populus and Salix host plants. Specific wing pattern differences from congeners not detailed in available sources.

Wingspan 85–95 mm. Forewings are dull-colored and serve as camouflage when at rest. Hindwings display bold, colorful patterns typical of underwing moths in the genus Catocala.

Associated with habitats containing Populus and Salix species. Exact habitat preferences not specified beyond host plant requirements.

United States: Vermont to South Carolina, west to Indiana and Illinois.

Adults on wing July to September, varying by location. One generation per year.

Larvae feed on Populus and Salix species.

• Populus - larval host
• Salix - larval host

Probably one generation per year. Larval stage feeds on host plants; adult emergence in mid to late summer.

Adults attracted to light. Typical underwing resting posture with forewings held together over back, concealing colorful hindwings.

Larval herbivore on Populus and Salix. Adult role in ecosystem not documented in sources.

Subject of interest to lepidopterists and moth enthusiasts. Adults may be attracted to fermenting bait mixtures used in moth collecting.
