Among the 17 species of Sympetrum found on the Korean peninsula Sympetrum vulgatum Linnaeus, 1758 had not been recorded since its first record in 1932 by Doi, suggesting the potential for misidentification. We observed a total of four specimens on September 21, 25, 30, and November 1 2022 in Goseong, Gangwon-do and collected each one male and female. We described the morphological and ecological characteristics of this species, conducted molecular analysis using mitochondrial COI, and addressed the controversial past record regarding its presence on the Korean Peninsula.
