There is an artical in this month BBKA news - Arrived this morning Called Rain and Bees.
So I did some reading and found some interesting articles:-
Honeybees’ foraging efforts vary according to a number of factors, including the time of day, food availability, and colony size. Researchers at Jiangxi Agricultural University in Nanchang, China, have now shown that bees may also adjust their schedules according to the weather forecast. The findings were published late last year (December 15, 2015) in Insect Science.
The researchers attached radio-frequency identification (RFID) tags to worker bees in three colonies, and then monitored their comings and goings through the hive entrance over the next 34 days. They found that bees spent longer periods out of the hive and worked later into the afternoon on days preceding rainy weather than on days preceding sunny weather. In other words, the weather of the following day determined the bees’ current foraging behavior.
In their paper, the authors suggested that the honeybees might be sensing and responding to temperature and humidity changes forecasting rainstorms, and foraging so as to maintain productivity accordingly. But Gene Robinson of the University of Illinois at Urbana-Champaign told New Scientist that this behavior would be unexpected, since honeybees are hoarding animals and therefore should not need to build up food stores for rainy weather.
Future work, the authors wrote, might address “what factors in the weather system are perceived and how bees communicate the need for behavioral changes to the whole colony.”
