Still nothing in the trap following the LBAM. However, 2 days ago my wife found this moth flying in our lounge and it turns out to be a new species for the site list, and, of course, the first new moth for 2012. There is a similar species, A. ciliella,  which can be distinguished by examination of the fringe on the hind wing. I've had a go at this and concluded that this is Agonopterix heracliana-a common species in Kent. The other species is any case extremely rare in Kent.
