In South Korea, a remarkable swarm of Lovebugs (Plecia nearctica) has captured public attention, particularly in Incheon’s Gyeyang District, where these insects have invaded Mount Gyeyang. A viral Instagram video depicts a hiker swarmed by the bugs, using a dustpan to clear countless dead Lovebugs from the hiking path, highlighting the extent of the invasion.
Accompanying footage depicts the ground blanketed with carcasses, while live bugs swarm above, creating a disconcerting scene. One observer noted that the carpet of dead and living bugs rendered the ground soft, even causing local stray cats to vanish. Many who dislike insects would find such an experience intolerable.
Despite their overwhelming numbers, Lovebugs are not disease carriers; however, they are notorious for flying directly into people’s faces. The proliferation of these insects in South Korea has been attributed to rising temperatures linked to climate change, which has provided an ideal breeding environment. Typically, Lovebugs are spotted in northwestern Seoul, the central business district, and Gyeonggi Province.
Reports indicate that complaints regarding Lovebug infestations have surged in 2023, a clear reflection of their rapidly increasing population. These quick-breeding pests emerge in large numbers during the Korean summer, making them a familiar nuisance, particularly in urban areas. Their distinctive appearance—red thoraxes paired with black wings—sets them apart, blending annoyance with a curious beauty in the natural landscape.
