On the second night of testing my new moth trap which boasts a 125v mercury vapour bulb I caught this beautiful Eyed Hawkmoth. If attacked by a bird it reveals the blue eyes and rocks itself. This has been shown to be an effective deterrent against small birds. The caterpillars of this species feed on the leaves of wild and cultivated willows, sallows and apples. It is not uncommon in the Southern half of Britain, but extremely rare in Scotland. We are near the Northern edge of this species range here in North Yorkshire.
