A blue butterfly which has been struggling for the last 40 years could be making a comeback, wildlife charity Butterfly Conservation has revealed.

During 2018’s record-breaking hot weather, Common Blue numbers soared across the UK, increasing by 104% on the previous year – and following this year’s heatwave, experts are predicting the butterfly could see its best ever summer.

In Wales their numbers were up 94% for the same period.

People should be able to spot these butterflies in National Parks areas as their caterpillars mainly feed on the wildflower, Common Bird’s-foot-trefoil. In England last year, the butterfly’s numbers were up 110% from 2017 and in Wales their numbers were up 94% for the same period.
