It is very interesting to see if anyone else in your area has seen this moth using the interactive map on this website. Somebody in Thatcham saw one on the same day as me (09/09/10), and of course you start to wonder if it was the same individual.
Note the picture on the website! It also shows the moth feeding on a type of Salvia - Buy one to increase your chances of attracting this enigmatic species.
