We are still celebrating Pollinator Week June 22nd through June 28th! 🎉The 2026 theme this year is ""Life on a Leaf: Celebrating Host Plants." Today's creature feature is the Imperial Moth Caterpillar. They are a species of royal silkworm moths also known as (Saturniidae). While these awesome creatures are not pollinators, we could not resist sharing a post on them. The Imperial Moth all their eating as a caterpillar and do not eat as an adult.The Imperial Moth Caterpillar eat leaves from a wide variety of tree species including oak, hickory, walnut, sycamore, basswood, maple, elm, beech, hornbeam, birch, some conifers and more. In his "Caterpillars of Eastern North America," Wagner says that “caterpillars feed by locking onto vegetation with their powerful anal prolegs (bugguide.net/node/view/1134273/bgimage) and pulling leaves or needles back over the body.” Although females lay lots of eggs, Imperial moths are not super common. Photos of both the caterpillar and the adult Imperial Moth were taken at Mothapalooza in Ohio by one of our staff naturalists. We have seen Imperial Moths and their caterpillars here at Wehr.
