40_42 Dorrington, Calaveras Co., 4800 ft. when the sun strikes them. At once the bees are at work. They visit or rather inspect innumerable blossoms in incredibly short time, but they linger for nectar an appreciable instant only on about one flower out of seven. The other they poise before only a fiftieth of hundredth of a second, and are off to the next. Either their sense of smell or of sight tells them that the flower has no honey-nectar. Apparently they do not gather the pollen. Corolla turns pink in age. Flowers open only for one day. At midday they begin to close and soon are all closed. It is remarkable and intersting that in shady spots the flowers tend to stay open all day! |
