Butterflies have vanished from towns and cities more rapidly than from the countryside over the past two decades, according to a new study. Industrial agriculture has long been viewed as the scourge of butterflies and other insects but city life is worse – urban butterfly abundance fell by 69% compared to a 45% decline in rural areas over 20 years from 1995. Butterfly species such as the small copper and small heath have suffered particularly disastrous urban declines, according to the study published in the journal Ecological Indicators. Scientists at Butterfly Conservation, the University of Kent and the Centre for Ecology and Hydrology found that numbers of small heath fell by 78% in urban areas compared to just 17% in the countryside, while small copper abundance fell by 75% in urban areas compared to 23% in the countryside.
