Lovebugs are not without enemies in nature. Larvae are found in extremely high numbers in pastures and other grassy areas, and make attractive prey for certain bird predators including robins and quail. Laboratory studies using invertebrate predators found in lovebug-infested pastures indicated they were voracious predators also. These included earwigs, beetle larvae and a centipede.
