Butterfly Conservation charity launches the Big Butterfly Count (July 12-August 4) to track climate change's impact on butterfly species.

Butterfly Conservation charity urges public participation in the annual Big Butterfly Count (July 12-August 4) to track climate change's impact on butterfly species. Over 50 years of data shows many species, including the Red Admiral, Holly Blue, and Comma, expanding their range northwards due to warmer habitats. The charity aims to understand changes in butterfly populations and inform conservation efforts.
