Seeing the Changes 15

The Gorse (Ulex europaeus) has apparently never been out of flower but is now a mass of yellow. White umbellifers, including Hemlock (Conium maculatum), and yellow crucifers are much in evidence near the river in Bynea. The first Greater celendines (Chelidonium majus) are out in the same location and the Rowan or Mountain ash (Sorbus aucuparia) is in flower in Loughor. There has been a sudden influx of Clouded yellow (Colias croceus) into the region. This butterfly is capable of quite impressive migrations (from Southern Europe to the south of Sweden).
