Warm weather may make 2019 a boom year for butterflies, say experts

Last summer, overall numbers of butterflies in England were up 110% on 2017 figures

The common blue butterfly could be booming in the UK thanks to recent spells of hot weather, according to a conservation charity.

Experts are predicting that the July heatwave and Met Office forecasts for above-average temperatures in August might mean that the common blue has its "best ever summer", Butterfly Conservation said.
