What might be the result of an exceptionally hot spring on wing pigmentation in the western white butterfly?

An exceptionally hot spring could lead to increased wing pigmentation in the western white butterfly as a response to higher temperatures. Darker pigmentation can help absorb more heat, potentially aiding in thermoregulation and survival during extreme conditions. Additionally, if warmer temperatures influence food availability or developmental rates, this could also impact pigmentation patterns as the butterflies adapt to changing environmental conditions. Overall, such changes could affect their fitness and reproductive success.
