Can Wasps Fly At Night?
Most wasps are diurnal, meaning they are active during the day and rest at night. However, some species are capable of flying at night, particularly those that are attracted to artificial lights or have adapted to nocturnal activity.
Species-Specific Behavior: Most common wasps, such as yellow jackets and paper wasps, are inactive at night. However, some tropical or parasitic wasps have evolved to be nocturnal.
Artificial Light: Some wasps may be drawn to porch lights, street lamps, or other artificial light sources, temporarily disrupting their normal rest cycle.
Temperature and Weather: Warmer temperatures may increase the likelihood of nighttime movement, whereas cold weather slows them down.
Disturbance: If a wasp nest is disturbed at night (e.g., by a flashlight or physical contact), wasps may become aggressive and take flight.
If you're dealing with a wasp infestation and considering nighttime removal, exercise caution—disturbing a nest at night can still provoke defensive behavior.
Do Wasps Fly At Night?
A few types of wasps are known to fly and remain active after dark. These include:
European Hornet (Vespa crabro) – Unlike most wasps, European hornets can be active at night, especially in warm temperatures or when attracted to artificial lights. They are known to hunt at dusk and even after dark.
Asian Giant Hornet (Vespa mandarinia) – This species, also known as the "murder hornet," can be crepuscular (active at dawn and dusk) and may continue activity into the night, particularly when raiding honeybee colonies.
Tropical and Subtropical Paper Wasps – Some species of paper wasps in tropical regions have been observed flying at night, often in response to artificial lighting.
Nocturnal Spider Wasps (Pompilidae) – A few species of spider wasps, particularly in warmer climates, can exhibit nocturnal activity. These wasps hunt spiders and can navigate in low-light conditions.
Polistes Carnifex (Executioner Wasp) – This large tropical wasp, found in Central and South America, has been documented flying in dim light conditions and may be active at night in certain cases.
Many nocturnal or crepuscular wasps are drawn to artificial lights, much like moths. If you're noticing wasps flying at night near your home, it may be due to outdoor lighting attracting them.
