iNaturalist Observations: In and Around the Republic of Korea (24 July - 12 August 2026)

Eastern Horse Cicada (Cryptotympana atrata)

I attended a pair of meetings (DH 2026 and DCMI 2026) in the Republic of Korea. After arriving in Seoul, I travelled to Daejeon for DH 2026 before returning to Seoul for DCMI 2026). The cicadas were in full force in both cities. While in Seoul, I took a day trip to Cheorwon-gun which was both beautiful and a great location for observations.
