Dolichovespula sylvestris (Tree Wasp)
General description:
The nests of tree wasps (Dolichovespula sylvestris) are not always situated in trees, although they require some cover. Many are found at ground level or even in cavities in the ground and in buildings. Like
most social wasp species they can often be seen on the flowers of hogweed, wild carrot and fennel, and they are important pollinators of common figwort. Although common in the Highland region of Scotland, it is not widely recorded in the islands of the Outer Hebrides
Diagnostic description:
The completely yellow clypeus (face) entirely yellow, or with just a small black central spot is the key field identification character.
