Climate Change Indicators - Peak Flight Time of the Common Footman Moth
The Common Footman moth (Eilema lurideola) 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 and the peak
flight time of the common footman moth has been shown to be negatively related to mean
May to July temperatures.
The graphs below show the mean flight time (expressed as a day number for the year) of the
common footman moth at ECN's sites and the mean May-July temperature at ECN's sites. A lower
day number would indicate that the Common Footman moth was active earlier
in that year.
