During the month of January, many species overwinter as eggs, larvae or pupae with only a few species overwintering as adult butterflies. Many hibernate in tree hollows, sheds, outhouses, barns and peoples houses. Only on clear sunny days with temperatures above 10° are you likely to get the rare chance to encounter a butterfly with the Red Admiral being the most likely species to be seen.
Its a risky strategy... if the temperature falls quickly, individuals which have become active may die unless they find warmth and shelter.
As the effects of global warming increase, so have the number of winter butterfly sightings with more records occuring over the last 5 years. |
