Up or Down?

Wednesday 29th October 2021, Norbury Hill

Our final visit of the Joy of Wildlife programme for 2021 was to Norbury Hill. This is near the village of Norbury which is about 5 miles north east of Bishop’s Castle and situated in the collection of hills to the south of The Stiperstones and west of the Long Mynd.

Confusion reigned as we did not visit Norbury Hill as identified on an OS Map but the hill next door to the east. Unfortunately this hill does not have a name on the OS map so, for convenience, we decided to stick to Norbury Hill as the site.

As we were meeting at Norbury Village Hall I was a little concerned as it was about a mile and a half from the site and considerably lower than the site we were going to visit! 

However, I need not have worried. The person who had arranged this visit for us had a plan, and unlike one of my plans, we followed it. 

On the day we gathered in the Hall’s car park. Then someone from the hall told us that the cars we had arrived in were cluttering up the car park making it difficult for mothers bringing their toddlers to the hall for their session later to park.

After a little negotiation another area managed by the village hall was opened up and we moved the cars there, freeing up the car park.

Back to the plan. We arranged ourselves into four cars and took these and parked higher up the hill and closer to the site. We were now only about half a mile from our target and about half of the height gain required had been achieved. 

Booted up and equipment in hand we made our way to the start of the bridle path that would lead to our goal.

Then we halted.

Our arranger informed us that there were two sites which they were interested in us taking a look at, a meadow and the hill-top.

“Which would you like to do first?” adding that it was down to the meadow and up to the hill.

“Up or down?”

As I know the group generally goes in the opposite direction to the one I would take I said nothing, but secretly hoped we would go up first.

It was decided.

DOWN we went, to the meadow that occupied a valley between the real Norbury Hill and the pretend one (but real in terms of height) that we were visiting.

The aerial photograph above shows the start of the valley in the bottom right corner. Where we parked was just beyond the trees in the top left hand corner. We had descended quite a bit of the height gained in the cars!

To be fair, the choice proved correct as the valley, especially the wetter area at the bottom centre of the photograph, proved to be very interesting and provided us with plenty of opportunities to exercise our invertebrate identification and other skills.


Damp grassland is home to a tiny planthopper, Conomelus anceps, which can be abundant in this habitat. It is normally very short-winged as in the photograph but long-winged individuals are often found.

It is also home to the much bigger planthopper Cicadella viridis.

The insect in the above photograph is a female. Males are smaller and their wings tend to be dark bluish in colour.

A Small copper butterfly was noticed and photographed.

Leaving insects aside for the moment, we have, what I think is a first for this extensive series of reports of the activities of the Joy of Wildlife group, a photograph of a liverwort. This one is Riccia sorocarpa.

By now noon had passed and thoughts of lunch started to germinate in one or two minds. But they were soon distracted by sight of the star of the day, a hoverfly, Sericomyia superbiens. It was seen feeding on a scabious.

It quickly drew the photographers attention!

Here is that star.

Not wanting to be completely upstaged a couple of dragonflies drew attention to themselves: 

A Southern hawker;

And a Common darter, which decided that one member of the group’s hat was an excellent place to perch. (I am not sure if he was wearing it at the time.)

Photograph: John Martin

Another inhabitant of damp places is the plant Lesser skullcap, Scutellaria minor.

For one of the group his desire for lunch could be ignored no longer. He declared UDL, settled himself down and started eating his food.

[UDL – Unilateral Declaration of Lunch]

Within minutes, nay, seconds others joined him and partook of their feasts.

All except one who remained on the look-out for hoverflies. He was rewarded.

Episyrphus balteatus.

Another Sericomyia, this time Sericomyia silentis.

And the star returned for an encore, justifying another photograph.

Lunch over we entered the second stage of the day, to take a look at the hill-top.

Which meant the time for UP had arrived.

To reach the path to the summit we could take the long route by retracing our steps up the gentler slope back to the start and then strolling up the gentler slope to the top, or we could …

And we did …

Take the shortest and steepest slope to meet the path.

UP we went …

Pause for breath and admire the view.

Photograph: David Williams

UP we continued …

A further pause for breath and admire some more of the view.

Photograph: David Williams

At last we reached the top and a longer pause for breath and the greatest period of admiration of the view.

The area shown the top and to the right of the following aerial photograph shows much of this upper site.

I am not sure if the following photograph of Eupeodes luniger was taken on the ascent or as we entered the second site.

Photograph: Jim Almond

This fungus, possibly an emerging Parasol, was taken on the heights.

Photograph: David Williams

We shared the site with a number of sheep who were happily grazing on the vegetation of this upland grassland. Where there are sheep, there is dung. And where there is dung there are invertebrates that make use of the dung for their own purposes. 

One such invertebrate is the dung beetle, Aphodius contaminatus.

Photograph: Jim Almond

And a Garden tiger moth larva was spotted lurking in amongst the vegetation.

Photograph: David Williams

We pottered around this area for a while before the relentless breeze and general exhaustion took over and convinced us to start the trek back to the cars.

On the way we paused for another look at the view. This time looking the other way, towards the Long Mynd.

Photograph: Bob Kemp

Over the last few weeks these reports have contained at least one photograph of a weevil. This indicates that we are no longer wary of these beetles as we have a member of the group who has embraced this group and is revelling in their delights.

This week is no exception. So, let me introduce this week’s Wednesday Weevil of the Week - Trichosirocalus troglodytes.

My thanks to the private owner of the valley site and the Middle Marches Community Land Trust who own the higher site for allowing us to survey, to Rob Rowe for arranging the trip and to the photographers for providing me with the material to enliven the report.

As this outing was the last of this year’s Joy of Wildlife programme, this report will be the last weekly report to appear until we restart next April. However, the group continues to meet over the off-season and I will periodically bring to you news of interesting finds or events.

To finish I would like to thank everyone who has attended the events this year for coming along and helping our recording effort and all of the people who have read the reports for the interest you have shown in what we get up to.

Keep well.

Quelle surprise!

Wednesday 22nd September 2021, Telford Millenium Village

I am not sure why I slipped into French for this report but it seemed, for some reason, to be more expressive that “What a surprise!”.

And what was the surprise?

I could leave you hanging and save it until later.

But no, I’ll mention it now.

A couple of us spent the day in the Brecks in Suffolk at Cavenham Heath National Nature Reserve. At the end of the day, as we were making our way back to the cars, we spotted a bird in the field which was worthy of further study.

Regrettably our binoculars were not up to the task of getting a good enough view of the bird to identify it. 

Fortunately, however, we noticed a couple who had a camera with a sizeable telephoto lens taking snaps in roughly the direction we had seen the bird.

We made their acquaintance.

“Could that have been a Stone Curlew that we had glimpsed?” we asked.

“Oh yes” they replied and pointed to a group of birds in amongst some grazing sheep in the middle distance.

Binoculars trained on this group we were able to see the birds very clearly.

And there were plenty of them. I counted 16. 

Taking a photograph was more tricky. My companion had the “wrong lens on” and had not brought the “right lens” with him. In desperation I set my camera on full optical zoom and managed this fuzzy shot.


At least you can tell what the bird is, if not the fine detail.

So, yes, “Quelle surprise!”. It was not an animal we had hoped to see at the site.

Right, back to the subject of this report, although there will be more about our trip to Cavenham Heath later.

Under blue skies on a lovely warm September day a baker’s dozen of us met in the capacious car park.
Actually eleven of us met, two had gone astray, suffering SatNav woes. They eventually arrived and we were not very late setting foot onto the site.

One member of the group who is also a volunteer helping with the care and maintenance of the site offered to guide us around.

“I have a rough route for us to follow” were his fateful words. 

I wished him luck.

I used to have plans for routes to take on these outings but soon realised that group dynamics tend to dictate where we go rather than my ideas. I have abandoned plans and reined my ambitions back to just getting people to the site and letting them loose. In the main it works well as we tend to stick loosely together and move in the same general direction.

No sooner had we entered the site en route to an area of heathland than we were distracted by the invertebrates in the hedgerow and rough grassland at the edge of the path.

Once again hoverflies dominated the invertebrates who were photographed:

Epistrophe grossulariae;

Melangyna umbellatorum;

Sphaerophoria scripta (this is a male making it easy to identify as its wings are shorter than the abdomen, a distinctive feature of this species);

Photograph: Jim Almond

Eupeodes luniger;

And Sericomyia silentis.

However other familiers jostled for their share of the attention.

A large fly, Tachina fera;

An Angle shades moth;

A pair of Rhopaliid bugs, Myrmus miriformis;

Photograph: David Williams

And a Green shieldbug.

Photograph: David Williams

Pied shieldbugs seemed to be quite common a few years ago, often being found on White dead-nettle basking in the sun. However sightings of this insect have declined markedly over the last few years. 

When a patch of White dead-nettle was pointed out to me “I’ve given up trying” was my off-hand response. However a feeling of guilt made me give it a quick sweep.

And what did I find?

Yes!

A Pied shieldbug!!!!!

Photograph: Jim Almond

We entered an area of heath that used to be covered in gorse but had been cleared by the efforts of the local volunteers.


There was still plenty of gorse but large amounts had been removed. My efforts to find Gorse shieldbug in the plant were unsuccessful but one was found by someone else.

Photograph: Nigel Cane-Honeysett

The white spots on the wings struck us as unusual as we could not recall seeing similar markings before. But, are they really markings or just two bits of white detritus that, by coincidence, happened to lodge in roughly the same part of each forewing? We will never know.

Finding a Tortoise shieldbug on a site used to be a significant event but they seem to have expanded their range considerably recently and we now come across them quite often. And this site provided us with another sighting.

Photograph: David Williams

Lunch was fast approaching but we still had time to find this well-marked Araneus diadematus on its web;

Photograph: Nigel Cane-Honeysett

And take in the view.


Lunch over our guide decided to take us to a different habitat within the site. It seemed quite a long walk to reach an area of wet marshy grassland as, unsurprisingly, many of us became distracted on the way by areas of banked grassland at the side of the path we were following.

Our distractions included the large and attractive staphylinid beetle Platydracus stercorarius;

Photograph: Jim Almond

A tiny “inconspicuous” ladybird, Scymnus limbatus, less than 2mm in length;

Photograph: David Williams

And a delightful fig weevil, Cionus tuberculosus.

At last we got to the area of wet grassland.

After all the distractions did we still have time left in which to explore?

Of course we did.

So we did.


Here are some of our finds:

A couple of Nettle-tap moths;

A picture-wing fly, Euleia heraclei;

A Silver Y;

And a Figwort sawfly larva.

“It’s been a while since we saw a Blue shieldbug” was the throwaway comment I made as we gathered together thinking about returning to the car park. 

And “Hey Presto” two minutes later one was found!

Photograph: David Williams

We started our return to the car park but, as always, there were distractions, including this Rose pea gall that was on a rose at the side of the stepped path we were ascending.

Photograph: Jim Cresswell

Unfortunately two species of gall-wasps are capable of generating this gall, Diplolepis nervosa and Diplolepis eglanteriae. The advice on how to determine which species caused the gall is to rear the adult. 

The gall was left in peace.

As we neared our destination a hoverfly, Eristalis arbustorum was seen and photographed.

Photograph: Jim Almond

At last we made it back to the cars.

Photograph: Jim Almond

And went home after another very enjoyable day.

My thanks to Telford and Wrekin Council and idverde for giving us permission to enjoy ourselves, our guide for the day and the photographers for capturing so many invertebrates on their cameras and allowing me to use the photographs in this report.

Other news

Shock! Horror!

On a moth night at The Bog recently we noticed a moth being carried away by a spider.

Photograph: David Williams

We recognised the doomed moth, a Silver Y, but what was the dastardly spider?

Fortunately our spider enthusiast was able to tell us that it was probably Eratigena duellica a species that is feeling especially mean and grumpy after undergoing a couple of name changes in the last few years.

The day before the visit to Telford Millenium Village a couple of us went to Cavenham Heath NNR (as mentioned at the start of this report). 

After a rather disappointing walk past uninteresting woodland on our left and a field on our right with an intensive pig farm on its far side, the site opened out into heathland on both sides. 

Regrettably the entrances to both sides were CLOSED.

Why?

To protect the plants and animals, apparently.

A little nonplussed we walked on.

Eventually we reached an entrance that was not locked, so we went in.

After a bit more unremarkable woodland we were able to take a small path across the heathland and spend most of the rest of the day seeing what we could find.

As we walked through the heather a Wasp spider made our searching easier by climbing onto my companion’s trousers.


We detached it and placed it on the grass

Continuing our searching of the vegetation we came across the slightly bizarre looking Rhopalid bug that is not yet recorded in Shropshire, Chorosoma schillingi.



And a Hawthorn shieldbug with which I tried my hand at taking an “artistic” photograph.


A Chrysomelid beetle wandered onto one of our rucksacks by its own volition, Sermylassa halensis;

Photograph: Jim Cresswell

And we were able to find several Long-winged coneheads in the grass.


We were not done with Wasp spiders.

As we looked at the edge of a grassed area we witnessed a spider capture a grasshopper (Field grasshopper, I think) which it wrapped in silk quickly then retired to the centre of its web.


The unfortunate grasshopper was still twitching as we moved on.

On leaving the heathland several hours later we noticed a jumping spider on the gatepost. My companion tried to photograph it but it kept moving around the post as soon as he managed to focus his camera on it. He tried from the side, back, other side and front but it just kept moving. I stayed put and was able to take this snap as it paused its rotation.


On returning home I sent the photograph to our local spider expert who declared it to be the “Fencepost spider”! 

Was he joking?

No, it really is known as the Fencepost spider, Marpissa muscosa.

With a name like that I am still not sure if he was serious.

Keep well.
