The Asian chestnut gall wasp (aka "Oriental chestnut gall wasp" on iNaturalist) is an invasive gall maker that was first found in New York around 2012. Today the species can be found in 17 different counties and infestations are most severe in western and southeastern parts of the state. Galling is detrimental to chestnut trees as it reduces nut production, leaf area, and shoot elongation. Galling can occur on almost all species of chestnut trees (excluding Ozark chinquapins and some European/Japanese hybrids such as 'Bouche de Bètizac"). During the growing season newly developed galls are green to rose colored and are typically found on the petiole or midvein of chestnut leaves. These galls turn brown and woody at the end of the season and will often remain on the tree for at least 2 years. If you believe you have found galls on your chestnut tree feel free to contact Chris Johnston at Additionally you can upload pictures to iNaturalist!
