In keeping with the drowsy heat of a humid August, the Hills and Holes are now painted in their late summer palette of bright purples and yellows set against the pale brown canvas of the drying grasses. The purple knapweed is particularly prolific, much to the delight of feeding insects, accompanied by good numbers of field scabious, clustered bellflower, harebells and, in places, thick banks of richly scented wild marjoram. Scattered amongst them are the bright yellow flower heads of the much-maligned ragwort (now greatly reduced thanks to the efforts of the volunteer ragwort-pullers) and the paler clusters of the wild parsnips. Most of the orchids are gone, leaving only dried out husks, but, surprisingly, a few of the frog orchids are still making a brave show of it. While you are on your knees, look out for the froth of small white flowers of the parasitic common dodder clustered together in patches on the gentler slopes. As for the insects, the chalkhill blues are now coming into their own with large numbers rising in clouds from the grasses on the hot afternoons and plenty of the crimson and black 5-spot burnet moths competing for attention. In the right places, there is a scattering of whites, speckled woods, gatekeepers, small coppers and peacock butterflies to be seen. Down by your feet, the grass is alive with grasshoppers and crickets while, further up on the ragwort, there are quite a few of the yellow and black striped caterpillars of the cinnabar moth still munching away.
