I'm glad i've found out what these pests are. I have been plagued with them for the past two weeks, and could do nothing but watch them munch their way through the flowers on my dahlias, roses and runner beans. And they love the bright yellow evening primrose! They have also been attracted to my washing!Weather has now deteriorated a bit (Gt Yarmouth area) so maybe there will be less pollen beetles about. Thanks for information.
