Yes, seen tissue moths in the Dales but no heralds yet.
I tend to notice these because for some time I've been reporting them to David Hodgson, who sadly passed away earlier this year. David studied them for over 5 decades and ran a BCRA field meeting at Scoska Cave in recent years which partly focussed on these insects.
David left a valuable archive of data in connection with his studies, which we hope will eventually be made available at some stage.
If you're seriously interested Mike, send me a PM and I can tell you a bit more.
