The harlequin ladybirds, Harmonia axyridis, are awakening from their hibernation in my window frames. Yesterday one of them walked across the carpet to my tiny plastic Dalek and bit it repeatedly all over, so I got my camera out. I'm not sure it counts as common nature exactly....
My wildlife identification skills don't extend beyond, "Ooh, pretty!", when it comes to beetles. This attractively burnished specimen landed on me whilst I was working in the garden today.
