Later on in the morning i visited the Charleston Bottom area and Friston Forest and found 2 White-Letter Hairstreak and a Brown Hawker along the ridge.
In the Forest were hundreds of Broad Leaved Helleborines, unfortunately another week before these are out in full flower.
On the bank there were many Small Skippers but i did manage to find an Essex Skipper amongst these, however it was a problem to photograph. Also many Brown Argus, Small Copper and a Chalkhill Blue.
