Britain’s Urban Butterfly Population Down 69% In two Decades – Study

‘Butterflies are disappearing more rapidly from British towns and cities than from the countryside, according to a new study taken over the last 20 years. The research blames a multitude of factors for the decline, including climate change.
The study, published in the May 2017 issue of journal Ecological Indicators, found that the number of urban butterflies fell by 69 percent over a 20 year period beginning in 1995, compared to a 45 percent decline in rural areas.
The study compared trends for 28 species in urban and countryside environments and found that 25 of those species had declined by more in city environments.
In particular, the research found that the Small Copper and Small Heath species suffered the biggest city declines.’
