Atymna castaneae
Atymna castaneae is a treehopper species in the family Membracidae, first described by Asa Fitch in 1851. It is a specialist herbivore restricted to chestnut trees (Castanea spp.), feeding on both the American chestnut (C. dentata) and Allegheny chinquapin (C. pumila). The species epithet directly reflects this host association. Its historical distribution across eastern North America has been impacted by the decline of its primary host due to chestnut blight.
