Description: The Tuscarora Emerald is a small moth with a 24mm wing span, although this is on the larger side for an Emerald. The wings are a light green with a yellow hue, and have two white lines that run from the leading edge to the trailing edge of the forewing, and continue through the back wing. On the forewing, the outer line is straighter than the inner line which veers towards the body at the leading edge of the wing. Both lines on the hind wing follow a similar pattern to the outer edge of the hind wing, although not exactly. The wing fringes are light yellowish green.
Similar species: The Tuscarora Emerald is similar to many other Emerald species. Some of them can be ruled out based upon their wavier am and pm lines. Those with straighter lines are more difficult to differentiate, although most have some type of white and reddish markings on the abdomen or along the wing fringe, while the Tuscarora emerald does not.
North American Range: It has been found in Ohio, Kentucky, Tennessee, Indiana, Maryland, West Virginia, Pennsylvania, North Carolina and Virginia. In Virginia, it has been documented in Rockbridge County.
