Bees are also picky in color

Not only to watch, this flower color is more colorful than other flowers turned out to be very useful, at least if you are a bee. The flower color preference of yellow-tailed bees ( Bombus terrestris ), in this case purple, can help them find more bile, the researchers found.

The researchers chose bees that had never seen real flowers in the bees in southern Germany, and exposed them to the purple or blue artificial flowers in the lab. They found that these bees (one of the most crowded bees in Europe) often prefer purple flowers, in an instinctive way.

Next, the researchers gave the bees and the same herd to collect bile in real flowers in nature. It turns out, the purple flowers that they choose are much more vivid than the green flowers. So, bees like purple get more honey.

"If you ask someone, everyone will say their favorite color, and now we find that it is actually very useful," said researcher Nigel Raine, from the University of London. know.

The researchers conjecture perhaps the bees formed the color preference to coincide with the most secretive flower. In fact, purple flowers or green flowers are also often the most eye-catching colors in many places of residence.
