Which non-biting fly is considered a major nuisance during the months of April through May in Florida?

Love bugs are recognized as a significant nuisance in Florida, particularly during April and May. This period coincides with their mating season, when these insects become extremely prevalent. They are commonly found in large swarms, which can create an uncomfortable experience for residents and visitors.

Unlike biting insects, love bugs do not harm people or pets, but their sheer numbers can be bothersome, especially when they swarm around vehicles, where they can cause vehicle damage by leaving stains on paint and windshields. Additionally, love bugs are attracted to heat and light, which further contributes to their presence around homes and cars during these months.

In contrast, fruit flies, horseflies, and houseflies, while they can also be considered nuisances, do not exhibit the same seasonal behavior or large swarm patterns observed with love bugs. Fruit flies are typically associated with decaying fruits and vegetables, horseflies are biting insects that are more active in warm months but are not as troublesome in swarms, and houseflies, while common, do not have a seasonal peak as pronounced as that of love bugs. This distinctive behavior and timing make love bugs the correct answer to the question regarding which non-biting fly acts as a major nuisance in Florida during April and May.
