South Korea, particularly the Seoul metropolitan area and Incheon’s Gyeyang Mountain, has been experiencing a large-scale invasion of insects known as 'lovebugs' or red-bodied Plecia longiforceps flies. These black flying insects, named for their mating behavior, have swarmed hiking trails, residential areas, and urban streets, causing widespread inconvenience and complaints among residents. The surge in lovebug populations has been attributed to rising temperatures linked to climate change. Local governments, including the Ministry of Environment and Incheon Gyeyang District Office, have responded by deploying eco-friendly pest control measures that avoid harmful pesticides, using sticky traps and other equipment to manage the infestation and dispose of insect carcasses. Despite the nuisance, authorities emphasize the ecological benefits of lovebugs as beneficial insects. The Gyeyang District Chief sparked controversy by urging citizens to be more tolerant of the insects. Legislative efforts have been initiated to protect citizens’ quality of life from the impact of these insects. Experts predict that the lovebug population will naturally decline and disappear within about a week to ten days. Meanwhile, social media videos show hikers struggling with the swarms, and some content creators have drawn attention by filming extreme eating shows involving the insects. Native bird species such as sparrows and magpies have been observed preying on the lovebugs, providing a natural form of population control.
