What is the white spot on my honey bees -is it a disease or mite?
It is October, autumn here in Scotland and my bees are taking advantage of a late spell of warm weather to gather stores for the winter. I can often tell what they are bringing in to the hive by the colours on their bodies. Some of the bees in the picture have a white spot on their backs. This is a good example where the bee has been touched by the plant whilst it has been raiding the flower for nectar. This crop of nectar which was swallowed by the bee will be regurgitated and turned into honey, and capped with wax for eating later when it is too cold to fly.
This is the plant that causes the white spot, Himalayan Balsam. A good source of food for bees in autumn.
