SMALL TORTOISESHELL Aglais urticae

Although the maps do not seem to show it, this species undergoes considerable fluctuation in numbers; some years it may be exceedingly abundant in the autumn and then periods of comparative scarcity may follw, even of several years' duration. Currently (2011) it seems to be making a recovery from such a period of scarcity. It is tolerant of agricultural land, provided there are some nettle patches, and also favours patches of waste land in towns as well as more semi-natural biotopes.
