In the summer we spotted Hornets catching bees and spiders. In addition to eating insects, in late summer and early autumn they can be spotted feeding on fallen fruit and sap from tree bark. They engage in feeding on plant tissues beneath the bark of trees and shrubs. This feeding has been observed on many types of trees and shrubs. We spotted these Hornets today feeding on sap and you can clearly see where they have stripped off the bark on this sapling to get to the sap.
