Answer
Yes, these data strongly support the notion that climate warming/global climate change is causing the butterfly species to shift its distribution to northern conditions, where the temperature is cooler and more optimal. Emergence time is occurring earlier, when the temperature conditions are optical for that stage of the species' life history.
