It was not alone. Why 'Mr Smug'? Because I've been saying almost from the start that I thought this moth excites everybody the first couple of times they see it, but people then realise it is potentially very bad news, a bit like Cameraria ohridella.
Anybody who reads the Herts and Middx Moth group utterances will know that Colin Plant attracted more than ten thousand to his light a couple of weeks ago - in one night (!) in Macedonia. This species can strip Box bushes bare, to the point of death.
