Small Tortoiseshell (Aglais urticae)


Probably Britain’s favourite butterfly, hibernating in our sheds and lofts and even in the cool spare bedroom, to wake in spring and breed, producing a short-lived summer generation that breeds in turn and gives us the autumn butterflies that, if all goes well, we see again next year. 


Images L-R:  The sexes are identical; underside; caterpillars on nettles


Flight period: Almost any month but most in March to May, June to July and September to October.
