The park’s ivy flowers between September and November; each plant’s flowering season is quite short but a succession of plants flowers all through the autumn. The flowers are small, green and yellow, and so insignificant-looking that many people don’t realise that that they are flowers at all.
In the world of invertebrates, black and yellow signals danger. It says to predators: I am poisonous or I will bite you. Read on to discover more:
A message from Ian:
May be of interest to you: Jerusalem Artichoke, Helianthus tuberosus, identified by Lindsay Moore [County Recorder Flora]. Ali and I found it along the stream near the bridge at the bottom of the Blackthorn Tunnel. I’ve added it to the Census. Unusual, probably from some bird dropping seed.
Unlike common wasps, honey bees (Apis mellifera) don’t die at the end of the summer. The hive stores enough food for the queen and the workers to survive through the winter.
.o.
By this end of the summer, the workers in a wasp nest will probably have finished raising and feeding the new queen larvae. The larvae have spun caps over their cells and begun the process of pupation. This indicates a change for the nest.
The Weed Act of 1959 requires landowners and occupiers to control the spread of five species of injurious weeds: ragwort, creeping thistle, spear thistle, common dock and curled dock. The Weed Act’s purpose was to increase the productivity of arable land and to protect livestock at a time, post WWII, when self sufficiency seemed at lot more important than ecology.

Like ragwort, creeping thistle (Cirsium arvense) is classed as an injurious weed by the Weed Act of 1959. Our hedges and edges are full of it: beautiful, pollen-rich, heavily scented flowers, buzzing with invertebrates, followed by seed heads elevated on stems sturdy enough to support seed-eating birds. Gorgeous.

The header picture is of a garden bumble bee (Bombus hortorum) in a spear thistle flower at the edge of the large pond.
On Wednesday, DKG and his macro lens took a close look at some of the park’s invertebrate inhabitants.

This is hogweed (Heracleum sphondylium), first cousin to the giant hogweed (Heracleum mantegazzianum) which the Daily Mail tells us has invaded Virginia, USA, and will blind us all.

On 21st of June, Hugh, Ian and Sarah G walked a regular transect through the park in order to survey the butterfly numbers.
This is a damsel fly: a beautiful demoiselle (Calopteryx virgo), another species indicating the unpolluted quality of the water courses in Southwick Country Park .
A message from Ian B on Tuesday of last week:
“Had a walk around the park this afternoon and did a bit of a butterfly transect. The park is looking good. I saw 3 speckled woods, 7 small skippers and 43 meadow browns – the latter were in perfect condition as though they had just hatched – the majority of the meadow browns were in Village Green.”
A few photos of an evening stroll in the park on Wednesday (23rd May).
This is the caterpillar of the drinker moth (Euthrix potatoria) so called because the caterpillar is believed to drink drops of dew on grass stems.
From Ian B:
“I photographed this small tortoiseshell nest this morning in Simpsons Field; there is a nettle bed on the right, about half way up the hard path from the entrance.”
This is an ichneumon wasp feeding on clog weed near Lambrok Stream.
Ring barking or girdling can kill a tree. It happens when the tree’s bark is removed right the way round its trunk. Accidental girdling may be the result of a carelessly used strimmer, or over-tight wires and ties; it might be mammals gnawing on the bark or, in the case of deer, rubbing their antlers against it.
Ragwort has many common names; in fact some, like stinking willie and marefart, are downright vulgar. Both refer to the plant’s unpleasant smell. Another set of names, staggerwort, stammerwort and sleepy-dose, are about to its toxicity. Then there is felon weed, swine grass and our personal favourites: scrog and weeby.

I found a bloody nosed beetle (Timarcha tenebricosa) in the short grass where the rabbits graze at the end of Sleepers Field.
Sunday morning, in the sunshine, Ian found and photographed this beautiful, newly emerged comma butterfly on Village Green.
Harlequin ladybirds are hibernating in substantial numbers inside the notice board at the park’s main entrance.
There were European Hornets (Vespa crabro) hunting in the Lone Oak in October. They are still quite rare in this country, but changing temperatures have extended their range as far north as Nottingham.
