Climate warming is changing the habits of bugs and butterflies, according to scientists. There is evidence that some butterflies are adapting to a warmer climate by adopting new habitats, according to Chris Thomas of the British Association Science Festival in Glasgow. ?A range of species which used to be solely in the south east are expanding north,? he says.
A butterfly called the silver-spotted skipper, previously confined to sunny south-facing slopes, is now able to move to new areas as the temperature gets warmer. In the last 20 years it has expanded its range and developed a 10-20% increase in muscle mass, so that it can fly farther.
