A Check List of the Lepidoptera of Beaver Creek State Park, Columbiana County, Ohio

Results of a comprehensive survey of Lepidoptera occurring at a 12,334 hectare natural area in Columbiana County. Ohio conducted in 1985 and 1990 is presented. Ten species of skippers, 27 species of butterflies and 597 species and forms of moths were identified and recorded. Euagrotis forbesi, and Spodoptera eridania had not previously been collected in Ohio; and Polia nimbosa and Idia laurenti have been designated as special interest since they are considered rare Ohio residents. The gypsy moth, Lymantria dispar was taken in bait traps and is the first record for that species in the Park. The presence of the gypsy moth, and the possibility of attempted eradication poses a definite threat to the survival of the species mentioned above with the exception of the southern army worm, S. eridama which was undoubtedly a fall migrant
