Most UK butterflies spend the winter as caterpillars or pupae but there are five species that overwinter in their adult form: brimstone, comma, peacock, small tortoiseshell and red admiral, all of them present in the reserve.
All these photographs were taken in the reserve.

Beautiful!!
I often find butterflies overwintering under an upended wheel barrow! Somewhere safe and dry to spend the winter.
That’s useful to know. We have to make as much provision as we can for our insects.
