Why white flowers open up only in the night?
It is not mysterious at all .





The plants / flowers are pollinated by insects that are nocturnal ( They are on the wings and move about only during the night time just like some animals and some birds ).





To attract them during their flight these flowers bloom during the night time . Moreover they do not waste energy on attractive colors as these will be invisible .





Instead they have heavenly fragrance !!!





So one is astonished by this insect flower relationship .
Reply:White flowers that are fragrant and open at night are usually pollinated by moths. The moths are attracted by the fragrance not by color.





Butterlflys prefer red floweres and bees prefer blue and yellow flowers.


Flies are atrracted to white flowers during the day.
Reply:it isn't all white flowers, and the ones that do are nocturnal.
