I was on the beach at Heacham yesterday and noticed that there were lots of bumblebees on the clumps of Marram Grass growing on the shingle. They were crawling over the flower heads. This is not behaviour that I have noticed before, and as Marram Grass is presumably wind pollinated I assume that they were collecting pollen. Is this usual behaviour?
I have heard of bees collecting pollen from grasses and possibly drinking fluid ( the dew?).
I don’t know much about this behaviour though.
Would love to hear of any other thoughts,
