A single pale spot near the tip of each wing is almost the only common factor between the One-spotted Variant's many individual manifestations.
True to its name, the One-spotted Variant comes in multiple shades and intensities. Overall, it is brown, but this may mean pale brown for one moth and tawny brown for another. One simple tan spot dots the tip of each forewing regardless of how deep the brown colors are. Small spots, speckles, and curved color bands can vary, making it difficult to immediately identify this species.
Caterpillars feed on the leaves of a variety of common trees like oak, maple, elm, poplar, and cottonwood. They also eat from fruit trees like apple, cherry, plum, and peach. The brown larva is easy to mistake for a short twig. Two broods are produced each year with the later brood overwintering before becoming an adult. They are popular food items for hungry birds during winter.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
