Identification
Members of the Eupithecia ('pugs') are readily recognized by their narrow wings and unique resting posture. E. indistincta is distinguished from similar by its chocolate brown wing coloration and geographic distribution in eastern North America. Positive identification to species level typically requires examination of genitalia characters, as many Eupithecia species are morphologically similar.
Habitat
Specific requirements are not well documented. Based on distribution records, occurs in regions with temperate deciduous forest and mixed conifer-hardwood forest. One observation from California suggests potential occurrence in dry, mixed conifer forest with oaks at approximately 7,000 feet elevation.
