Wildlife charity Butterfly Conservation said that while the hot, dry spring and one of the warmest autumns on record saw butterflies on the wing from early March all the way through to December, the cold damp summer saw many species struggle.
Its Big Butterfly Count this year revealed numbers of common species were down 11 per cent in the face of a miserable summer.

The warm weather returned in autumn, prompting the arrival of a number of migrant moths from as far as southern Europe.
