Luna moths drift through eastern North American forests like glowing green spirits, instantly recognizable by their luminous lime-colored wings and long, elegant hindwing tails. These spectacular giant silk moths live only a single week as winged adults, dedicating their brief lives entirely to finding a mate under the cover of darkness. Lacking mouthparts or a digestive system, they rely completely on energy stored during their voracious caterpillar stage.

Responsible observation
Minimize Outdoor Lighting: Use warm LED or motion-activated outdoor lights to avoid disorienting these nocturnal navigators.
Observe Gently: If one lands nearby, admire its delicate wing scales and feathery antennae without touching, as handling can rub off the protective scales.
Search Near Host Plants: Look for caterpillars on the undersides of sweetgum, walnut, and hickory leaves during late summer.
