June Bug Day is observed on June 7 and celebrates the visibility of June bugs, which belong to the Phyllophaga genus. These beetles emerge from the ground during this time, having spent up to three years as larvae. Adult June bugs are typically about an inch or shorter, with a hard brown or black casing and wings, and they are nocturnal, becoming active at dusk. They are attracted to light, often swarming around it, which can make them a nuisance for humans. June bugs primarily feed on leaves, grass, flowers, and decaying organic material, and their feeding habits can lead to damage in gardens and lawns. The name "June bug" reflects their emergence in late spring or early summer, and their scientific name, Phyllophaga, translates to "leaf eater."
