Please see #1 for main description of the walk.
The White-letter Hairstreak is one of our more-elusive butterflies as it flits high in the treetops, often appearing as a dark speck against the sky.
Elm is the sole foodplant and this species suffered as a result of Dutch elm disease in the 1970s and early 1980s, especially in southern sites.
