Lovebug mating season typically lasts four weeks and occurs in both May and September. Lovebugs are found in the southern United States, as far north as North Carolina. During mating season, lovebugs swarm in large masses.
During lovebug mating season, 40 or more males form a swarm. Females fly into the swarm and pair with males. After mating, the lovebugs stay intertwined and search for a place to deposit the female's eggs. Lovebug swarms limit visibility for drivers when they coat car windshields. The swarms can cause vehicles to overheat by covering the grill of the vehicle, which limits airflow to the engine.
