It's most likely to be pollen.

This time of year most likely rosebay willow herb? We have lots. Is there much around where you live?

Tall thing with loose pink upside down ice cream cone of pink flowers on top. Common on waste land, verges, railway embankments etc. Google images is your friend....and the pollen can make the brood on the other side of the brood frame look a bit alarming too.
