There is good news in The Guardian for the common blue butterfly. The charity, Butterfly Conservation, claims that its numbers could boom in the UK thanks to recent spells of hot weather. Seemingly the July heatwave and Met Office forecasts for above-average temperatures in August might mean that the common blue has its “best ever summer”.
According to the charity, the butterfly has been struggling for the last 40 years, but common blue populations increased by 104% in the summer of 2018 compared with the previous year, thanks to warm weather.
Dr Zoe Randle, Butterfly Conservation’s senior surveys officer, said: “People should be able to spot these butterflies in national park areas as their caterpillars mainly feed on the wildflower and common bird’s-foot trefoil.”
It could also be a record year for the painted lady butterfly, which is covered in orange, brown and white markings.”
