Polyphemus Moth

Fascinating facts about the Polyphemus Moth

• A newly hatched caterpillar can consume an astonishing 86,000 times its own weight in just eight weeks, providing the energy needed for rapid growth. The larvae feed heavily on their host plants, which may include elm, birch, willow and many others, reflecting their highly polyphagous diet. During this feeding burst they can reach a length of three to four inches as bright green caterpillars.
• The hindwing eyespots of the Polyphemus moth are shaped like the head of a great horned owl, creating a startling false face for predators. These large purplish eyespots form a classic startle pattern that distracts attacks away from the body. Although the display often leaves the wings damaged, the moth retains full flight capability.
• Male Polyphemus moths will travel miles through the night to locate a calling female, guided by the scent she releases at dusk. Their plumose antennae are equipped with trichoid sensilla that house pheromone-responsive neurons, allowing detection of the female's pheromones from great distances. Male attraction peaks in the two hours before sunrise.
• When a Polyphemus caterpillar is gently prodded it produces a rapid series of clicks with its serrated mandibles, typically between fifty and fifty-five clicks that can continue for more than a minute. This acoustic alarm is immediately followed by a defensive regurgitation that is expelled toward attacking birds or mammals.
• In the late 1950s amateur lepidopterist Gary Botting succeeded in crossing the Polyphemus moth with two Asian silk species by moving the pheromone-producing scent sacs from female Polyphemus into Antheraea females and then allowing Polyphemus males to mate with them. The hybrid offspring were showcased in his award-winning U.S. National Science Fair exhibit on intergeneric hybridisation among giant silk moths. After consulting with genetic statistician J.B.S.

As the sun sets over the forest, a gentle giant stirs, its delicate wings unfolding like a map of the heavens, adorned with eyespots that shimmer like moonlit pools. The Polyphemus Moth, a creature of unhurried majesty, glides through the twilight with a soft, whispery flutter, its feathery antennae twitching as it navigates the scented currents of the night air.
