It was worth taking a photo of yet another small fly, as this one turned out to be a different species again. This is a burdock gall fly (Terellia tussilaginis). They have this pale green colour and brown banding on their wings. The larvae live on burdock flowers, causing galls and live in the old flowerheads over the winter.
