Though climate change is detrimental to many species, Great Britain’s brown argus butterfly, once a declining species, is thriving.

They previously only fed on rockroses, but warmer temperatures over the past few years have allowed geraniums to grow earlier, attracting the brown argus. Over the past 20 years, the butterfly’s range has expanded approximately 49 miles.
