Hemileuca eglanterina
Sheep Moth, Common Sheep Moth
Hemileuca eglanterina, commonly known as the sheep moth or common sheep moth, is a day-flying saturniid moth native to western North America. The species exhibits remarkable geographic variation in coloration, ranging from nearly black to pink/yellow to the typical orange with black markings. Adults are short-lived and lack functional mouthparts, relying entirely on fat reserves accumulated during the larval stage. The species has been documented in coevolutionary dynamics with Argiope spiders, which appear to lure male moths using chemical mimicry of female moth sex pheromones.
