I have not been able to find the answer to my query but know that someone here is bound to know the answer... and it's probably ever so simple!!

Butterflies and bees fly from flower to flower checking on nectar availability. Sometimes they dive in and at other times they go to another flower.

My question: does nectar continue to develop and mature in the flower so that it is worth the insect going back to check in case more is ready? Or once it is supped is that it?

Thanks
