Warming in Great Britain appears to have given a little brown and orange butterfly an edge. The brown argus butterfly has spread about 49 miles (79 kilometers) northward on the island over 20 years, observations indicate.
Although it's well known that climate change can prompt plants and animals to shift the ranges in which they live, the brown argus (Aricia agestis) has widened its living quarters with unusual speed, according to an analysis of decades of data collected by British volunteers.
