This year’s Big Butterfly Count recorded fewer butterflies than in any previous year.

Common Darter

Yesterday afternoon, at the bottom set-side in Village Green, I was chatting with an old chap who, as a boy had played in these fields, when I saw a pair of dragonflies flying by.

Canada Thistle Gall Fly
by Ian Bushell
This afternoon, I found these galls on the Creeping Thistle in the second set-aside in Village Green. They are caused by Canada Thistle Gall Fly, Urophora cardui. This is a very distinctive fruit fly which, despite its name, is indigenous to the UK and Europe.
Continue readingFact of the week
The scientific name for the seven spot ladybird is Coccinella septempunctata; if you had the right magic wand, a spell like that would put spots on anything.
Ivy flowers
The reserve’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.

Southern hawker
A late summer southern hawker photographed in the reserve last week by Clive Knight. The southern hawker’s flight period runs from the end of May right through into November but each individual dragonfly lives for only around six weeks. This one, to judge by it’s faded colours and torn wings, is approaching the end of its life.
The summer’s drought made difficulties for our dragonflies. Many of the shallow pools along the Lambrok dried up completely and the big pond, Grand Central Station for our Odonata, was reduced to a mere puddle. Not only do all dragonflies and damselflies need standing water for successful breeding, but so do their flying insect prey: nowhere to lay eggs, nothing to eat, not a good year.
Willow warbler migration
Most of our willow warblers will have left by now; they will be on their way to sub-Saharan Africa where they will spend their winter. Theirs is the longest journey undertaken by any of the park’s migratory birds. Why do such tiny birds fly so far and take such risks to do it?

Hibernation
The nighttime temperature is dropping and soon we will see the first frosts. The reserve’s invertebrates are preparing for hibernation.
Continue readingWinter song
Robins, both male and female, sing almost the whole year round with just a pause after the breeding season, when they go into hiding for the moult.

Ecosystem engineers
Ecosystem engineers are organisms that modify their environment. They increase biodiversity by creating habitat for species other than themselves. The oak apple, caused by a tiny wasp called Biorhiza pallida, is just such an engineered environment.
Continue readingOne for sorrow, two for joy…
There are several families of magpies in the reserve. This year’s crop are, as yet, short-tailed, loud- mouthed and clumsy, hanging out in gangs and still learning to fly properly. But, despite their dramatic black and white beauty, their reputation is poor.
Read on:Acorns
Oak trees produce thousands of acorns every year. Somebody has worked out that an oak tree can produce ten million acorns over its lifetime. In a good year, they carpet the ground under the tree and crunch underfoot.
Read on:Camouflage
A recent study has found that the best kind of camouflage, out there in the wildwood, is pretending to be an inanimate object.

Hornet queen
A hornet, drinking at the Iris Pond, photographed by Clive Knight. Ian Bushell, our entomologist, has identified it as a queen.

This is a common drone fly (Eristalis tenax), named for its mimicry of a male honeybee. It was first identified in the reserve in 2019.

GCN
At the end of August, Ian checked the pond that we are developing with Wiltshire Wildlife Trust in the hope of attracting great crested newts to the reserve.
(Here are some links to previous posts about the pond’s development: ONE TWO THREE)

The Guardian reports that a European pine marten (Martes martes) has been spotted in London for the first time in more than a century.

Wasps
By the end of the summer, the workers in a wasp nest will 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.
Read on:Cantharidae
There are forty one species of Cantharidae in Britain and almost all go by the common names of soldier or sailor beetle.
Read on:Wood pigeon
Wood pigeons (Columba palumbus) are our largest and most common pigeon. Gregarious, very adaptable and given to flocking in enormous numbers at this time of year, they are an everyday sight in British towns and countryside.
In towns they seem unafraid but in the park they are shy and wary. Often the first indication that they are there at all is the loud clattering and clapping of their wings as they take off and fly away. Their call is the lovely, familiar background noise of spring and summer.
Yarrow

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.
