The Ohio Lepidopterists maintains a Collection of Ohio Butterflies and Moths at the OSU Museum of Biodiversity in Columbus. With the recent donation of the Parshall Collection to OSU the Museum of Biodiversity is the premier source for Ohio Butterfly specimens/data.
The Ohio Lepidopterists, with support originally from the Division of Wildlife, conducted a State wide survey of Ohio's butterflies and moths. TOL still maintains the State database of moth and butterfly records from Ohio and welcome new verified records.
