Winter Butterfly 171214Posted: December 17, 2014
Today I let a Peacock butterfly out of the window of my house. It is mid December but the weather is mild.
We have a number of butterflies – mainly Small Tortoiseshell (Aglais urticae) and Peacock (Aglais io) – who appear to hibernate in our house. When the weather is mild they wake up. I am never sure whether to let them out or not. Would staying in the house mean further hibernation or slow starvation as they flap helplessly against the windowpane? Letting them out into the changing weather can only mean certain death as their life force is drained by the cold and lack of nutrients from their natural food sources.
From childhood I was taught that a butterfly’s life lasts but one day, as it emerges from its chrysalis with shimmering wings, drinking briefly from its chosen flowery nectar, choosing a mate and exhausting itself in procreative fervour. This seems not so or at least not entirely accurate. I have read that the Painted Lady butterfly (Vanessa cardui) reaches British shores after a migratory flight from northern Africa and Spain, while obviously the Peacock and Small Tortoiseshell often spend a winter, at least, in dry dark sheltered roof spaces and cupboards before embarking on life once more.
As this butterfly flew out into the dim blustery day I wonder on how much more misinformation I have been fed during my formative years, and if this brief liberation, caused by my own puzzled intervention, was truly for the best…
