- Published laboratory work suggests that Aglais urticae may be affected adversely by drought, as the larvae thrive on actively growing plants with high leaf water and nitrogen.
- The weekly counts from the Butterfly Monitoring Scheme were used to test the hypothesis of an association between changes in abundance and drought in field data.
- The analysis supported the hypothesis; breeding success of the summer generation from 1976 to 1995 was greater when the early summer weather was cool and wet than when it was warm and dry.
