|scientific name Euchlaena madusaria |
Dry woodlands in the montane, prairie, and southern boreal region.
In Alberta the peak flight activity is from late June to mid July.
Ground colour yellow-tan with fine, well-defined AM, PM and subterminal lines. Outer third of forewing darker, more pronounced than in other Euchlaena, with a contrasting pale apical dash. Forewing margin smooth not serrate as in johnsonaria, lacks pronounced discal spots of E. obtusaria.
The adults are nocturnal and come to light. Up to 225 eggs are laid, which hatch in about ten days. The grey brown striped larvae resemble twigs, and overwinter when nearly mature (McGuffin 1981).
Not of concern.
Prentice (1963) reports two larval collections from buffaloberry (Sheperdia canadensis) in the Alberta foothills, and one collection on douglas-fir (Pseudotsuga menziesii). McGuffin (1981) also lists jack pine (Pinus banksiana) as a host, but given that Prentice (1963) reports only one collection of madusaria from a conifer out of the thousands of conifer tree samples, confers are not likely usual hosts. Records of this species at prairie localities where both conifer
