Lovebug - Management

Management

Lovebugs are subject to some significant natural controls, such as various parasitic fungi, and dry weather—which dries out the thatch resulting in a higher mortality rate for the immatures. As the lovebug migrated around the Gulf Coast, first to Texas, then Louisiana, then further eastward, the initial populations for many years were so excessive that they caused public concern and initiated rumors of their origin. However, as pest populations migrate naturally, their natural controls are usually not far behind. While it often took decades, lovebug flights are no longer present in the huge numbers that once existed simply because their natural controls (mostly fungi) caught up with established populations. In many areas, local lovebug flights may only be present in excessively large numbers due to occasional local conditions that may not be repeated in successive years.

While lovebugs are not a favored food of most insectivores due to their acidic taste, lovebug larvae—and some adults—are food for birds such as quail and robins. Arthropod predators include spiders, some predatory insects such as earwigs, at least two species of beetle larvae, and centipedes.
