Dainty Sulphur is a southern species. Both 2012 and 2019 had below normal rainfall in the autumn. Because of the drought, hay was brought into Maryland from other states (per Bick Borchelt). At Grist Mill Trail there was extensive replanting in 2019 (because of the removal of Bloede Dam) in which the exposed ground was replanted and covered with straw. The River Road Trail in the Orange Grove section of Patapsco Valley State Park is across the river from Grist Mill Trail.
