Just at the moment, almost all the flower-visiting insects in my garden are covered in white pollen from
Impatiens glandulifera (Himalayan Balsam), but I agree that the white distribution on the thorax is odd - it doesn't look like a fungal infestation to me, nor do I think it is a natural colouration. (A strange little mystery! :D)
