A Heliconius erato demophoon butterfly feeds on a flower in this photo released on June 1st 2016. A gene responsible for the colours and colour patterns on the wings of butterflies and moths has been independently identified in two separate studies published in this weeks ‘Nature’. This gene, and a mutation associated with it, controlled the darkening of the peppered moth that took place during the Industrial Revolution, and the gene is also responsible for the natural colour pattern variation in certain butterfly species.
