A 22-year-old man visited our clinic with a 1 month history of pruritic, multiple and erythematous papules with crust. At first, he was asymptomatic, but the bites subsequently became hard and developed into pruritic papules. There are many small black flying insects in the Gangwon province where he worked. He found that some of the insects had attached to the skin lesions, and so were brought to us. They were identified as blackflies, of the Simulium sp. Since there have been no reports of blackfly bite in Korea, we herein report a case of blackfly bites by Simulium sp.
