The wing tips of the Curve-Toothed Geometer Moth are unlike those of almost every other moth, pointing the way to its identity.
The only moth in its genus, the Curve-Toothed Geometer Moth has many distinctive markings that should help in identifying it. When at rest with wings flat, a definitive line that crosses from left to right stops short of reaching the edges of the wings. This line separates dark brown coloring near the head from the lighter brown color at the edge of the wings. The outer edge of the forewings curves downward and ends in a nubby point, or tooth, at the tips of the wings. The hindwings have scalloped edges.
A young caterpillar has a brown body that becomes darker and more purple as it ages. It eats the leaves of common trees like ash, oak, and maple. This easily accessible food source makes it almost effortless when expanding its range. Two generations are produced each year in warmer climates. Adults are active from late spring to late summer in wooded areas across the continent.
