It needs to be between 34.5 and 35.5 degrees Celsius (approximately 94-96 degrees Fahrenheit) or it adversely impacts the brood (eggs, larvae, and pupae), so the bees work to maintain that ideal temperature in various ways, such as fanning with their wings to cool or shivering …
WebRegardless of the outdoor temperature, honey bees have to maintain their winter cluster at close to optimal temperature (34–35 °C). This requires a significant amount of energy which bees generate via thermoregulatory behaviors such as clustering, fanning, increase in metabolic rate, and locomotor activity (Kronenberg & Heller, 1982 ).
