impacts stingless bee foraging activity.
Weather impacts stingless bee foraging activity, with flight typically starting at 18∘C and ceasing in cold, rain, or high winds. Extreme heat is also dangerous, as hives can overheat, so they require shade in summer but sun in winter. The key difference is that cold weather halts all external foraging, while hot weather requires active management to prevent overheating.
Temperature
Ideal foraging range: Native stingless bees begin foraging when temperatures rise above 18∘C
Cold weather: Activity ceases entirely when it's cool. On a hot, sunny day above 20∘C, they should be active; if not, there may be an issue.
Hot weather: Extremely hot weather (38∘C and above) can cause hives to overheat. Be sure to provide shade in summer, especially in the afternoon, and avoid western-facing sun traps.
Other weather conditions
Rain: Bees will not forage in the rain.
Wind: Activity decreases in wind stronger than 24.1km/h (15mph).
Cloudiness: Cloudy conditions can reduce activity, especially when combined with near-threshold temperatures.
Management based on weather
Winter: Position hives to receive as much direct sun as possible.
Summer: The hive needs to be heavily shaded from afternoon sun.
Extreme heat: On very hot days, you can use a moist, light-colored towel over the hive or a pot plant to create shade and keep it cool.
