What does continuous rain do

Bees in the rain

How does prolonged rainfall affect bees?

Have you always wondered what effects prolonged rainfall has on bees? Where are all the insects all of a sudden when it rains? Can raindrops even kill the little hymenoptera? NABU provides answers.

Raindrops are comparatively huge for insects and can even become deadly projectiles - especially for flying insects such as flies, butterflies or bees. In addition, the flying insects can hardly get up into the air if they are soaked with water and therefore have to carry more weight.

That's why bees don't like rain. When it rains, but also in cool temperatures, the hymenoptera stay in their beehive, warm and feed the larvae and live on their reserves of pollen and nectar. If the rain takes a break, some workers fly out to fetch drinking water.

If a bee is surprised by the rain, it quickly hides under leaves, in flowers, on trees or under house roofs. There she holds out until the rain shower has passed.

Long periods of rainy weather can even be life-threatening for bees and their colonies. With continuous rain for days, bees can hardly collect pollen and nectar. As a result, many bees starve to death and the bee colony is severely weakened. In addition, cool, damp weather makes the bees sluggish and more susceptible to disease.
