yellow butterfly

The Clouded Yellow butterfly is a beautiful migrant butterfly that we look forward to seeing every year here in the south west of Cornwall. Although seen annually numbers fluctuate wildly. In some years we’ll only see a handful and yet in others, as in the most recent years of 2006 and 2013, we have enjoyed the wonderful spectacle of hundreds flying over a single coastal field.
These ‘Clouded Yellow years’, as they are often referred to, coincide with warm summers, large broods abroad and winds emanating from Southern Europe and North Africa.
