South Korea has recently been hit by another surge of lovebugs. But romance is certainly not in the air for residents of Seoul and neighboring Incheon city, who have been plagued by these pesky insects in recent weeks, as rising temperatures due to climate change spur their spread.

Lovebugs are swarming parts of South Korea, covering mountain peaks, homes and other places. These insects, known as Plecia nearctica, typically appear between late June and early July.
