Aglais urticae is a very common resident. Migrants are also often seen. Its distribution probably has not changed during the last century. However, the Dutch Monitoring Scheme shows a decline in numbers in the 1990s; the cause is not known. Adults can be seen looking for nectar in gardens, parks and on roadside verges. The caterpillars feed on the smaller plants of Urtica dioica in very sunny, open spots. The species flies in two generations from the beginning of March until the end of October. The adult butterfly hibernates in cool, dark places, such as barns, attics, or hollow trees.
