For some time now, I have been finding increasing numbers of little moths appearing in the room where I store the teasel poles. I've finally had time to look them up.....Endothenia marginana. 
The larvae feed on the seed heads of the teasel (among other plants),  from September to June, emerging as adults from late May to August, so I've got a few more months of moths: (see http://ukmoths.org.uk/show.php?bf=1099)
Apparently they're quite common, which is a good thing considering just how many I've sucked up with the hoover, in one of my more manic cleaning up phases!
