Over 33 degrees centigrade today on Jakob's Knowle and the first of the Chalkhill Blues on the wing. If the weather stays fair expect to see numbers slowly increase over the next few weeks. They will be at their most numerous by the end of the month. Another good site is at Swells Hill.
Join the walk on the 31st July to see Chalkhill Blues, Adonis Blue along with other grassland species
