This last month’s
warm weather has helped to ripen the barley, oats and wheat and some
farmers have already started harvesting. However, with all the recent
rain showers the combine-harvesters have had to be put on hold until
a sunny moment returns. We certainly need the rain because of the
drought-like weather and the lack of water in our aquifers bringing
on the imposed hosepipe ban. We will need a lot of rain because because
the recent dry conditions creates the risk of fire to our heathlands.
The heathlands were beginning to turn brown with the heat where many
of the Bell Heath and Cross-leaved Heath flowers had gone over. With
the present rain however, the Ling heather flowers coming through
on the heaths will turn them purple again. Look out this month for
evidence of badgers where the harvesting has taken place. You may
come across where the badger has taken advantage of the surplus bedding
material, in the form of straw and hay, which they roll back to their
setts in plenty of time for the winter ahead.
The farmers
will soon be working hard bringing in their crops of wheat, oats
and vegetables such as potatoes. Already fields have been ploughed
and harrowed or disked. It is good for conservation when the farmer
cuts their crop and leaves some of the headland edges to give the
insects nectar from some of the arable flowers to feed on. Headlands
also act as cover for small rodents and small birds from predators
like foxes and hawks. Also the longer the farmer can leave stubble
in the fields the better it is for the smaller creatures to find
a food source in the form of cereal seeds. In the wetter areas,
that have herb-rich grassland, it is good to graze at this time
of year to help remove the coarse growth and give the finer-leaved
plant species a better chance to grow next spring.

| Common
Centuary (Centaurium erythraea) |
A plant to look
out for this month is the pink-flowered Common Centuary (Centaurium
erythraea). It can be found in a number of habitats including dry
grassland and woodland edges but it especially likes sandy grassland
and chalk downland. The plant can be very variable in shape and
size. It has long been sought-after as a remedy for wounds and various
diseases and it has even been reputed to remove freckles. It was
named after the centaur named Chiron who in mythology was half man
and half horse. “Chiron” knew all about herbalism. One
day he was attacked by Hydra, the nine-headed serpent, and bitten
and he thought he would surely die. However, remembering all he
had been taught he used this pink flower to treat his wounds and
survived to live another day.

| Yellow-wort
(Blackstonia perfoliata) |
Another plant
to look out for is Yellow-wort (Blackstonia perfoliata). It can
be found in the same habitats as the Centuary, especially on the
chalk downs. It is an unusual plant in that the stem leaves are
parallel up the stem and fused together giving the appearance that
the main stem has pierced its way through them. This characteristic
is referred to in its scientific name “perfoliata”,
which means through the leaves. The other part of its scientific
name “Blackstonia” derives from a botanist John Blackstone
who used it for its medicinal properties, which was supposed to
help alleviate bad tempers and nervous disorders.

| Slender
Thistle (Carduus tenuiflorus) |
There are many
species of thistle to be seen now but one that is often over-looked
is the Slender Thistle (Carduus tenuiflorus). It is mainly found
along the British coastline on sea cliffs like at Seven Sisters.
It has purple flowers and slender stems and grows up to a metre
high. Occasionally it has been found growing inland along motorways.
The combined fast wind action of motor vehicles and the salt on
the roads in the winter allow for this migration of a species that
would normally be confined to the coast.
 |
| Common
Restharrow (Ononis repens) |
Another flower
to look out for is Common Restharrow (Ononis repens). This pink-flowered
plant has long been associated with annoying many a farmer who tried
to plough their fields by horse. They would find themselves grinding
to a halt as the plough became tangled up with the matted stems
of this plant. The harrow was the implement that became stuck the
most, so this flower soon became known as “Restharrow”
and the name has stuck ever since. Farmers also disliked it being
where cattle grazed because it causes their milk to taste unpleasant.
Obviously, with the introduction of the many horse-powered tractors,
this plant could not hold up the ploughing and so today, it is only
found on the edges of fields and areas where the modern day plough
has not been.

| Six-spotted
Burnet moth
(Zygaeria filipendilae) |
One of the colourful
day-flying moths to look out for is the Six-spotted Burnet moth
(Zygaeria filipendilae). It is the commonest of the seven species
of Burnet moth found in this Country. They sometimes appear black
with red spots, but if you look closer, you will see that in the
correct light they can appear bronze-green. The bright colours warn
off predators, as they are poisonous to eat. The poison comes from
vetches and trefoils that are processed into hydrogen cyanide “prussic
acid” when eaten as a caterpillar.
 |
| Marbled
White butterfly
(Agapetes galathea) |
Another majestic
insect to look out for this month is the Marbled White butterfly
(Agapetes galathea). It is found in areas of grassland again especially
on chalk downland. The butterfly has mottled black and white patterning.
The caterpillars feed on many species of grass, however they especially
like to feed on Sheep’s-fescue and Cock’s-foot grasses.
Next month will turn cooler and I will tell you what to look out
for.
