Yesterday I spotted a new guest in our garden. It looked like a cross between a bumblebee and a common cockchafer, complete with the wings of a dragonfly. Flitting between the flowers of the periwinkles, it would land briefly to take a sip of nectar before winging its way towards pastures new. What strange creature is this? It’s a broad-bordered bee hawkmoth – a harmless butterfly that has taken on the fearsome appearance of a bumblebee.
