Marbled Fungus Weevil
Euparius marmoreusAlso known as Marbled Anthribid
Marbled fungus weevils blend seamlessly into the mottled bark of decaying hardwoods, where their intricate brown, black, and white markings mimic lichen and bird droppings. Unlike true curculionid weevils, they lack long curved snouts, featuring broad, flattened mouthparts tailored for chewing through tough polypore fungi. Adults and larvae spend their lives in close association with bracket fungi like turkey tail, contributing directly to wood decay and nutrient cycling across eastern North American forests.
