Fox-and -cubs is one of my favourite wildflowers. Its Latin name is hieracium aurantiacum, but it is also known as Devils paintbrush, orange hawkbit or Grim the collier. The reason it gets the name fox-and-cubs is because of the way the unopened flowers hide under the larger opened ones. Rather like small fox cubs hiding under the vixen.
I have several of these flowers growing around my wildlife pond and I took this video. If you look carefully you can see small whirligig beetles swimming on the surface of the pond.
