The brilliant display of green color on the Showy Emerald is perfectly partnered with crisp white lines.
The Showy Emerald Moth lives up to its name. The green wings may have a bluish hue, but they are bold even without it. When wings are open flat, a bright white line crosses all four wings to form a 'V' that is unmistakable. Each upper forewing has a short white line near the 'shoulders' as well. All four wings have a single, tiny black dot near the center and a white fringe. The outer edge of the forewings appears dirty, with dark speckling near the head and face. Antennae are white and are usually tucked under the wings. The body is white and the legs have some black color at the joints.
Caterpillars eat poison ivy leaves, which exude urushiol, an oil that most people are allergic to and results in tremendously itchy blisters that take weeks to heal, even if they are broken open. They also feed on winged sumac shrubs and staghorn sumac trees. They are brown and textured, with a flat back covered in brown plates. Two broods can be produced each year.
