<span style="line-height:16.383333206176758px;font-size:10px;font-family:Verdana,Arial">February 2013. In a new study, Hamilton College Biology Professor Ernest Williams and Boston University researchers have found that butterflies show signs of being affected by climate change in a way similar to plants and bees, but not birds, in the Northeast United States. The researchers focused on Massachusetts butterfly flight periods, comparing current flight periods with patterns going back more than 100 years using museum collections and the records of dedicated citizen scientists. Their findings indicate that butterflies are flying earlier in warmer years.</span><div>
