White-letter Hairstreak

[Roger Gibbons]

The progress of the White-letter Hairstreak project by Liz Goodyear and Andrew Middleton was presented at a Herts & Middx BC branch meeting this afternoon. The findings may be quite surprising to some of us: WLH appears to be much more common than generally thought and (for much of the UK) wherever there are healthy elms, there are WLH, even in central London. Localities have been found in regions where WLH was not known to exist.

The objectives and the modus operandi of the projects are given here:
