Briseis Underwing, Ribbed Underwing

Catocala briseis is a medium-sized underwing in the Erebidae, distributed across the North American forest region. are active from July to September and possess the characteristic underwing : cryptic forewings that conceal brightly patterned hindwings. The was first described by William Henry Edwards in 1864.

Identification

Distinguished from other Catocala by specific forewing pattern and hindwing coloration, though detailed diagnostic features require examination of specimens. The species name and "ribbed underwing" suggest structural differences in forewing venation or scaling. Separation from similar underwing species typically requires close examination of forewing markings and hindwing color patterns.

Distribution

North American forest region from Newfoundland to the Pacific coast; south to Massachusetts and Pennsylvania. Records from Canadian provinces including Alberta, Manitoba, and Saskatchewan, and US state of Vermont.

Seasonality

active July to September, with timing varying by location.

Diet

Larvae feed on Populus , including Populus tremuloides (quaking aspen), and Salix species (willows). feeding habits not documented.

Host Associations

  • Populus tremuloides - larval quaking aspen
  • Populus - larval level
  • Salix - larval willow

Life Cycle

Complete with , larva, pupa, and stages. Larval stage feeds on plants. Specific details of site, stage, and other elements not documented in available sources.

Behavior

are . Like other underwing moths, adults typically rest with forewings folded over the body, concealing the brightly colored hindwings. When disturbed, they may flash hindwings as a startle defense. Attraction to light not explicitly documented for this , though underwing moths generally are not strongly attracted to lights and may remain on the periphery of light stations.

Ecological Role

Larva functions as a folivore on Populus and Salix. may serve as prey for and possibly as a , though specific ecological interactions not documented.
