South Korea, particularly the Seoul metropolitan area and Incheon’s Gyeyang Mountain, is experiencing a large-scale swarm of insects known as "lovebugs" or red-backed March flies (Plecia longiforceps). These black flying insects, named for their mating behavior of flying in pairs, have proliferated due to rising temperatures attributed to climate change. The swarms have covered hiking trails, mountain peaks, residential areas, and city streets, causing widespread discomfort and complaints among residents and visitors. Local authorities, including the Ministry of Environment and Incheon Gyeyang District Office, have initiated eco-friendly pest control measures using non-chemical methods such as sticky traps to manage the infestation and dispose of insect carcasses. Despite the nuisance, experts note that lovebugs are beneficial insects. The infestation has led to thousands of complaints to Seoul city officials, and a lawmaker from the People Power Party has proposed legislation aimed at controlling the lovebug population to protect citizens’ quality of life. Officials estimate the swarm will largely dissipate within about ten days. The Gyeyang District Office head has urged the public to exercise patience amid the ongoing situation.
