map 174 Newbury & Wantage
All day
This walk was a
replica of the spring visit we made here in our post for 27 May, so that the
description of the route there will suffice.
Many of the summer flowers that had emerged since then had by now gone
to seed, unfortunately, so that at an early August visit would generally be
preferable - although that would miss the Chiltern gentian, which was just
coming into flower, and the peak period for clustered bellflowers.
A full list of chalk flowers seen on
this occasion is appended; only the more interesting highlights are mentioned
here.Beside the track up Kingstanding Hill was a tall clump of the alien cotton thistle Onopordum acanthium, still statuesque although the flowers were over, ghostlike in its downy whiteness. We also passed several plants of vervain Verbena officinalis, whose narrow spikes of small flowers were much more difficult to distinguish from the background vegetation, and spurge laurel Daphne laureola in the shade of the hedgerow. There were many plants of another of the majestic thistles, woolly thistle Cirsium eriophiorum, which on our last visit were only leaf-rosettes, but all were now in seed. Apple mint Mentha x villosa was a well-established garden escape , enjoyed by a variety of bees, flies and beetles.

By the open track,
Fair Mile, was tall grass with pale toadflax Linaria repens, golden melilot Melilotus
altissimua, tufted vetch Vicia cracca
and even a patch of the rarer spiny rest-harrow Ononis spinosa surviving on a less overgrown bank. Near the latter
scuttled the black carrion beetle Silpha
atrata, with a narrow head used for attacking snails. A lizard was basking
in a bare patch until we surprised it.
Red-legged partridges abounded, sometimes running for hundreds of metres
along the path in front of us instead of flying off into scrub at the side. Buzzards flew above.
A corner of an arable field with a
maize crop had a number of interesting casuals, such as small nettle Urtica urens, field pansy Viola arvensis, common fumitory Fumaria officinalis (subspecies officinalis and wirtgenii), common poppy Papaver
rhoeas, luxuriant black bindweed Fallopia
convolvulus, the unusual common amaranth Amaranthus retroflexus (with very hairy stems distinguishing it
from green amaranth), and the increasingly scarce henbit dead-nettle Lamium amplexicaulum.

In the Aston
Upthorpe combe clustered bellflower Campanula
glomerata dominated in patches, perhaps the greatest concentration we had
seen of this plant, comparable to the chalk milkwort seen here in the spring. There were also many patches of harebell Campanula rotundifolia and seedheads of
dropwort Filipendula vulgaris, which
had come and gone since spring.
Similarly, the orchids were now difficult to identify spikes of
seed-pods but would seem to include pyramidals Anacamptis pyramidalis. On
the other hand, the autumn gentians Gentianella
amarella were still mainly in bud.

Many butterflies
were enjoying the sunshine - meadow and hedge brown, small heath, large white,
peacock, small tortoiseshell, brimstone, common blue, small copper, speckled
wood and even a, presumably migrant, clouded yellow, still in good condition. The abundance of flowers even at this late
date attracted many of the greenish Lucerne Plantbugs Adelphocoris lineolatus. The
old juniper Juniperus communis bushes
also harboured many insects, particularly the small shiny domed black ladybird
with two vague reddish spots, Heather Ladybird Chilocorus bipustulatus, and the Juniper Shieldbug Cyphostethus tristriatus. (We searched for caterpillars of the rare
Juniper Carpet moth but did not find one.)
Many of the clustered bellflowers had galled spikes where the flowers
were replaced by swollen leafy clusters, caused by the mite Aculus schmardae.
This former reserve was the only place
on the walk with short enough turf for the thymes Thymus polytrichus and pulegioides
and squinancywort Asperula cynanchica.Surprisingly, it was not until we walked into Aston Tirrold that we saw any dark mullein Verbascum nigrum at the roadside. In the village were also pellitory-by-the-wall Parietaria judaica.
On our return we diverted, as before, to Riddle Hill, where there was little in the way of short turf as at the Aston Upthorpe reserve, but did have lots of devilsbit scabious Succisa pratensis, clustered bellflower and many other chalk grassland plants seen earlier. Here we saw a brown hare.
By the lane going up to Aston Upthorpe reserve there was the alien rose with sprays of small flowers
Native catmint Nepeta cataria has been recorded from many places along this walk in the past, but we were disappointed not to find single plant. It seems to disappear from known sites and re-appear at new ones, so that we have only seen it when expected on some of our walks.
