Climate Change Indicators - Peak Flight Time of the Orange Tip Butterfly

The Orange Tip butterfly (Anthocharis cardamines) is a widespread species in the UK. The timing of insect activity is very weather dependant and butterflies are most active when conditions are warm. Warmer temperatures also result in earlier flight times. The peak timing of the orange tip butterfly is negatively related to mean January to April temperatures. The graphs below show the mean flight time (expressed as a day number for the year) of the orange tip butterfly at ECN's sites and the mean January-April temperature at ECN's sites. A lower day number would indicate that the Orange Tip was active earlier in that year.
