Saturday week ago I walked one of my regular circuits, touching the edge of Cardiff Bay near the swimming pool and ice rink, following the riverside Taff Trail a while, then veering inland across a recreation area called The Marl and around the edge of Grangemoor Park. As I walked the path between the pool and the ice rink, something small and light coloured fluttered up from a scruffy area that has been colonised by a colourful mix of wildflowers. A Clouded yellow (Colias croceus)! I don’t usually see these butterflies until much later in the summer so I’m guessing this gorgeous burst of sunshine in insect form was blown north by the heat-wave southerlies during the last week of May. Fortunately for me, the butterfly settled again very quickly and close to the path so I was able to get a few photos.
