Some of these, such as yarrow, are commonplace and put on a good show whatever the mowing regime. Others are doing much better than usual and brightening up the verges no end. One such species is Black Knapweed, Centaurea nigra. It is welcome in its own right but is also a plant frequently visited by a range of insects including some interesting picture-winged flies of the Tephritidae family.
Black Knapweed is otherwise known as Hardheads. Christchurch Drive,
