We live in northwest Florida and usually get them in late April-early May and September and they hang around for a few weeks. The bugs drift around slowly in the air while attached for mating (see photo in above post). They are really quite small, much smaller than they appear in the ilustration, and they do not bite or sting. They tend to fly in large groups and are especially drawn to white, yellow, and orange surfaces (from our experience). They are a nuisance in that many people really don't like bugs landing on them, and when there is a heavy infestation they will coat the front of your vehicle and need to be washed off. We've never seen them as heavy as in the windshield photo above. We tend to just ignore them and brush them off if they land on us. But try not to dine outdoors during love bug season as they will land on your food.
