Yes. So long as there is enough moisture in the soil for there to be a sap flow in the plant, the production of nectar is a continuous process until the flower wilts or the petals fall.
Hypothesis 1: Bees have a color preference for yellow flowers over purple flowers, regardless of nectar production. Hypothesis 2: Bees are more likely to choose flowers based on nectar quantity rather than flower color.
Bees make honey from nectar gathered from flowers. If there are no nectar-bearing flowers available, then the bees can't make honey. Nor will there be any nectar to feed on, so they will feed on their stored honey.
Fruit bats will eat/lick nectar from flowers. See attached link for more information.
They gather a flowers nectar, but while they do that, the flowers pollen gets on the bee and when he goes to the next flower he drops some of it and more sticks to him, that how flowers pollenate.
No, butterflies do not spread pollen with the purpose of creating other flowers. Butterflies may inadvertently transfer pollen between flowers while they feed on nectar, but this is not the primary way that flowers are pollinated. Other pollinators like bees, birds, and wind play a more significant role in pollination.
Bees prefer fragrant, red coloured flowers like roses. Yellow, scentless or purtrid smelling flowers are frequented by flies. I have however seen hungry bees on Dandilions and dasies. Hunger seems to be a great motivator.
In terms of what species of plant, the flowers are geared to be attractive to pollinators, often specific pollinators such as a bee - evolution took care of that a long time ago - flowers that were attractive to pollinators were always going to set more seed. As for flowers that still have nectar - they haven't already been visited and the nectar taken. If you watch a bee at work you will see that they can't detect that but most flowers will continue to produce nectar or they will wither once they have been visited and pollinated.
Bumblebees also pollinate wildflowers. Bumblebees are attracted to flowers with narrow corolla tubes, such as blueberries and cranberries. They mainly forage for pollen rather than nectar and transfer more pollen to the pistils with each visit.
Bees gather nectar from flowers, which they use to make honey. They also collect pollen from flowers, which they use as a food source for themselves and their larvae. Additionally, bees help with pollination when they visit flowers, which is essential for the reproduction of many flowering plant species.
Bees will eat most sugary things,they like honey the most.I have read most articles and everyone else said that they eat honey.Read more: http://wiki.answers.com/What_does_bees_eat#ixzz1UYIx1CCH
A bee flies from flower to flower, eating the sweet nectar. In doing so, it's hairy legs rub against the flowers anther, collecting pollen. The bee then flies to the next flower to eat some more nectar. The pollen falls off the hairy legs and onto the flowers stigma, from where it travels down to the ovary. Pollination then occurs. This is how bees fertilize flowers
The reciprocal evolution of flowers and insect mouth parts has occurred over millions of years. The flowers change to make their nectar inaccessible to insects while insects change to be able to attain the nectar.
