Glossonotus crataegi
Quince Treehopper
Glossonotus crataegi is a treehopper species in the family Membracidae, commonly known as the Quince Treehopper. The species was described by Fitch in 1851 and is native to eastern and midwestern North America. Treehoppers in this genus are characterized by their enlarged pronotum that forms distinctive helmet-like or keeled structures. G. crataegi is associated with host plants in the Rosaceae family, particularly Crataegus (hawthorn) and Cydonia (quince), which is reflected in its specific epithet. The species is part of the diverse North American treehopper fauna and has been documented in multiple states including Connecticut, Delaware, Illinois, Iowa, and Maine.
