Country diary: the remains of harlequin ladybirds suggest predation by a rodent

Cavenham Heath, Suffolk The woodland reveals beetles both common and rare, and a surprising pile of ladybird wings

Blue sky, still air and the winter sun have lifted the heavy overnight frost. Cavenham Heath contains one of the largest blocks of heathland and acid grassland in the south-west Breckland, but the path from the car park starts in a predominantly birch woodland. Tearing a weathered birch polypore (Fomitopsis betulina) from a standing trunk, I fumble through its white flesh. It is shot through with burrows and in places under the pale leathery skin it is dry and powdery, while elsewhere the fungus retains a tough marshmallow consistency.
