Pollen identification gallery
This gallery contains photographs of pollen collected within foraging distance of my honey bee colonies, here in rural Northumberland. The pollen was collected from plants when they were in flower.
The purpose of this gallery is to provide a way of initially identifying a pollen from its overall appearance. For many of the distinctive ones this can be enough but limitation of light microscopes may mean that it is only possible to identify the family.
The pollen gallery photos are in alphabetic order by common name. Try using the filter buttons below to filter by pollen load colour or by one of the top 10 families. See the similarities of pollen within the same family.
