December notes

Wednesday 6th December 2023, Marl Pool, Radbrook

This wet woodland site is surrounded by existing housing on three sides and housing being built along the fourth side.


The Shrewsbury branch of the Shropshire Wildlife Trust asked us to visit the site. They were interested in getting information to help them decide what management action, if any, they need to take to care of this parcel of land. 

The site was a pool, or maybe two pools, in the past. The pools had disappeared as the site succeeded to woodland. 

The decision was, should they try to restore the pools, or leave it as it is. They asked us to look to see if there were any species whose habitat they may destroy should they try to recreate the pools.

It was a dry but very cold day that accompanied the well wrapped-up group as they wandered onto the site. Note the frost on the nettles!


Venturing off the path to suction sample a large patch of nettles that had grown in a small clearing we were able to find this attractive moth, Caloptila falconipennella.

Most of the trees had grown tall in competition for light. As a result there was very little for us to sample within our reach, thus most of our searching was in the ground flora, smaller bushes and dangling ivy.

We were able to prise out a 10-spot ladybird;

And a Cream-spot ladybird.

Planning ahead I wandered off to see if I could find a suitable lunch spot. As I neared the far side of the wood I was surprised to find a large recently cleared area.


I returned to the rest of the group where we were joined by the local councillor. He was rather surprised at the clearance. The cleared area belongs to the developers, however, the councillor was unaware of their intentions. It did not look suitable to build on. Perhaps they were going to create a pool. To date I have had no indication of is planned in this area.

It was not yet quite time for lunch so we carried on searching, finding a harvestman, Nemastoma bimaculatum;

And a tiny spider, Paidiscura pallens, close to a vacated “sputnik-like” egg sac.

At this point we came across the find of the day. A largish planthopper.

Unfortunately, as I tried to get it into a pot to look at it, it hopped away.

But not too far, it was still in the tray.

I tried again, and failed, as it hopped off out of the tray.

It disappeared into the clothing of one of the group.

I assumed that that would be the last we saw of it.

It wasn’t.

It hopped from the clothing back into the tray. And, this time, I was able to get it into a pot.

Photograph: John Martin

And what a find, Acericerus ribauti. This is a recent arrival to the British Isles and, as far as I know, this was the first time it has been recorded in Shropshire.

I noticed that our equipment was tired and having a rest.


The hint was taken. Time for lunch. We took advantage of the tree felling and rested on some of the laid out trunks.

As we lunched a couple of neighbours called over to us to find out what we were doing. The councillor went over to chat to them. They told us the area had been cleared within the previous two weeks and that the area supported Great-crested newts.

Lunch over our Great-crested newt “certified” members searched for signs of their presence whilst the rest of us rambled around looking for other things.

Unfortunately, no Great-crested newts or signs of their presence were found.

We had a brief discussion about what advice we could give Shrewsbury branch. It was felt that there would be little to be gained by attempting any clearance and it may be best to leave it alone as “Wet Woodland”, which is an important habitat in its own right. It remains to be seen what becomes of the developer’s area.

Then, we went home.

Wednesday 13th December 2023, Venus Pool

Our last visit prior to the short break we take for Christmas was to the Shropshire Ornithological Society’s reserve at Venus Pool.

From the car park, after the usual meeting and greeting had been completed, we marched to the area of arable land which is used to grow feed for visiting birds.

The first area that took our interest was some of the marginal grassland that was covered with some sheets of corrugated iron. Peering under them, hoping to find slow worms or grass snakes, we had to make do with a Netted slug, which was trying its best, by stretching out, to try and imitate one of the target species.

Also hiding under the metal sheets were these fungi.


We moved to the border of the planted area and suction sampled the vegetation. A huddle formed as we examined the findings.

The findings of interest were:

A 22-spot ladybird (on the left) and Rhyzobius litura (on the right);

And a large rhopalid bug, Stictopleurus punctatonervosus;

This species of bug is not found very often in this area so it was exciting to find four others and a nymph over the course of the morning.

Continuing the examination of the various samples taken our favourite wasp was spotted, Callitula pyrrhogaster;

And here are a few of the many 16-spot ladybirds that we found during the day.

Photograph: David Williams

The morning progressed. It was dry, but there was a very cool breeze. This brought about another huddle.


Normally this indicates that something of great interest has been found, but, on this occasion, I think they were imitating Emperor penguins in the Antarctic in efforts to keep warm.

Scanning round The Wrekin came into view.


The sun came out.

That was the sign the huddle was waiting for and they headed off to one of the hides to have lunch.


During lunch we observed the birds on the pool. Furthest away were Shovelers and Teal with a Gadwall coming in to land.

Photograph: David Williams

Nearer to the hide was a group of Lapwings.

Photograph: David Williams

Every now and then the lapwings would be spooked and they would take to the air en masse, swirling above the pool for a few minutes in murmuration like activity before settling back on the pool.

And nearest was a Robin keeping an eye on us and hoping for scraps from our lunches.


We left the hide and headed for the marshy area of the site, where we spent the rest of the afternoon.

Here we spotted a clutch of Giant willow aphids on a Willow.

Photograph: David Williams

The willow was quite abundant and a small group met in its midst to discuss how to escape from this jungle.


A moth was caught, Agonopterix ocellana.

Photograph: John Martin

And this beetle, Galerucella sagittariae, was taken by surprise.

Photograph: John Martin

The marshy area proved to be a rich source of snails. Here are a couple:

Vertigo substriata, also known as the Striated whorl snail;

Photograph: Mags Cousins

And the aptly named Prickly snail, Acanthinula aculeata.

Our time was up. 

We made our way back to the car park, wished each other all the best for Christmas and the New Year and dispersed to our homes.

I wish all the readers of these reports a Merry Christmas and a Happy New Year. 

Thank you all for your support and interest in the adventures of the group.

My thanks to Shropshire Wildlife Trust (Shrewsbury Branch), Shrewsbury Council and Shropshire Ornithological Society for allowing us to do what we enjoy doing. My immense gratitude to the photographers for sending me their images to illuminate the report.

November notes

Wednesday 15th November 2023, Colemere

We were treated to a glorious autumnal day for this visit. We parked and met in the visitor car park, discussed which direction we should circumnavigate the mere, agreed, then immediately went the other way (should I be surprised) by starting in the large meadow.

Our first sighting was of some black cattle which were grazing the meadow. Three or four stopped what they were doing and stared at us. Then, one of them proved extremely friendly and said hello to our Dipterist.


Perhaps it was hoping that he would get his pooter out and remove the flies that were pestering it.

They followed us for quite a while until someone else arrived on site and wandered off onto the meadow. The cattle seemed to think he was more likely to give them what they wanted and trooped after him, leaving us alone.

Early activity was at the edge of the mere where the plants were being examined closely and photographed extensively.


And this is what had been found under one of the leaves.

Photograph: David Williams

Three species of ladybird. From left to right: Coccidula scutellata; Coccidula rufa and Water ladybird.

After the copious amount of rain that had fallen in the previous days the meadow was very wet and parts that were normally dry were flooded.


Within the meadow there is an area that is meant to be wet. On this occasion it was very wet, but it did nor stop one member of the group wading in to see what he could find.


I would like to think he found this:

Photograph: John Martin

A curlew. However, this was an opportunistic photograph of a passing bird snapped later in the day.

It may have been in this area where the shore fly Trimerina madizans was found. This is a fairly scarce species of wetlands that eats the eggs of wetland inhabiting spiders in the genus Hypselistes. It’s a handsome little fly sporting shiny black livery and bright orange legs. 

Photograph: Nigel Jones

Moving on we checked out the rougher vegetation at the edge of the meadow. Here we disturbed a rather groggy Silver Y.


You often come across these moths during the day when walking through grassland. Generally you see something fly away from you and settle at a “safe” distance. As you try to follow it, it will almost inevitably fly away again as soon as you start to get close enough to identify it. As you can see from this photograph, this moth had lost its get up and go.

Continuing our circumnavigation, we entered the wood. A Common darter was spotted resting on a tree. An attempt to photograph it resulted in it flying away. We saw where it went and tried again, with the same result. Fortunately, we were able to follow its flight as several other unsuccessful attempts were made before it finally decided to pose for us.

After this chase things settled down as we were able to concentrate on  more sedentary species as we made our way through the wood.

Having exited the woodland, we were now at the far side of the mere in a small open area of grassland. Glancing through the trees, bushes and other poolside vegetation we were able to see the church, on the far side, picked out by the mid-afternoon sun.

 
As time was marching on, we raced back (more like ambled with a purpose) through the woodland glade bordering the mere. To be fair, apart from a few fungi, there was little to observe.

Back at the grassland by the car park we had a last search before returning home.

Wednesday 22nd November 2023, Benthal Edge

We have visited the woods along Benthal Edge quite frequently, but have always been at the foot of the edge and never the top. This visit changed that as we wandered along the summit footpaths.

Having met in Benthal Hall car park we made our way along a lane to the Edge. There was a little dallying as the hedgerow was tapped and patches of vegetation suction sampled, but, on the whole, we got to the woodland fairly quickly.

Reaching the wood, the path divided with one going left and one going right. There was a third path that went down but temptation to take it was curtailed as this was closed due to a landslip.

Unfortunately, the path did not prove very interesting entomologically and very few species yielded to our efforts to find them. 

Here are photographs of a few species that we did find and were able to photograph.

A pseudoscorpion, Neobisium carcinoides, with its meal, a captured springtail.

A beetle that we were only able to identify to genus, not species, Asaphidion.

Photograph: John Martin

A harvestman Rilaena triangularis. This species has recently suffered the indignity of having its name changed – it used to be Platybunus triangularis.

Photograph: David Williams

A bristletail, again we could not identify the species only the genus, Dilta. Just look at those eyes!

Photograph: David Williams

A spider Cyclosa conica, its name seeming to reflect its conical shape.

Photograph: John Martin

Another harvestman, Nemastoma bimaculatum, with its two white patches on a dark body.

And a bit of a curiosity, a larva with what looks like caked mud between its legs.

Photograph: David Williams

Are they clumps of mud or are they parasites that have covered themselves in detritus?

I do not know, do you?

Wednesday 29th November 2023, Corbet Wood, Grinshill

You may have noticed that I have yet to mention success in finding Snow fleas recently. Although it is early in their “season” we had hoped to find them in the sites we had visited. With this in mind we visited Corbet Wood where, a few years before, several had been found.

Corbet Wood is a former quarry on the side of a hill that has naturalised with woodland. There are also some patches of conifer.

As usual, after getting ready, we dallied in the car park as a patch of rough grassland with marginal bushes and trees was investigated. Eventually it was suggested that we headed to the spot where Snow fleas had been found before.

We “raced” to that spot, skirting past the upper quarries…


And down a long descending path …


To the path that followed the foot of the site.

We followed the path for a short way to “the spot”.

Search as we might, we could not find any Snow fleas.

Very disappointing.

Down, but not out, we then concentrated on what was there rather than what was not.

An early surprise for us, and for it, was a Tawny owl that our rummaging in the undergrowth disturbed. Unfortunately all that most of us saw was a flash of wing feathers as it disappeared into the woodland.

More sedentary was this Common wasp.

Photograph: Neil Nash

And this long-legged harvestman Dicranopalpus ramosus agg.

Photograph: Nigel Cane-Honeysett

Why the agg.? Well, there is at least one other species that looks the same and rather than having to kill and dissect it to determine the species we just lump them together with the “agg.” suffix.

A cluster of 7-spot ladybirds.

A tightly rolled up Pill millipede.

A ground beetle, Notiophilus biguttatus.

A pair of spiders, Drapetisca socialis, living up to their name.

A fungus, Purple jellydisc.

Photograph: Neil Nash

A quarry wall in this lower section of the site attracted a good deal of attention.


What were they staring at?

A tiny indentation in the stone face in which a Forest bug nymph had stationed itself.

Photograph: David Williams

We were making slow progress along the bottom path as species of interest (except Snow fleas) kept turning up.

A Scarlet tiger moth larva.

Photograph: Nigel Cane-Honeysett

A harvestman Nemastoma bimaculatum whose description I mentioned above when we found it on Benthal Edge.

Photograph: Nigel Cane-Honeysett

And a very common and distinctive fly Mesembrina meridiana, known as the Noon-day fly as that is generally about the time of day you find it, on sunny days, resting on the vegetation.

Photograph: David Williams

For a change I wandered up the slope a little way and found two enormous fungi. I have no idea what they were but am happy to be enlightened. Here is one of them.


The object at the bottom of the photograph, to give you a sense of its size, is my boot.

Reaching a gently sloping path that seemed to return us to the start we ignored it and carried on along the path at the bottom. This passed some houses then joined a lane. After a few yards the lane veered off to the right and some of the group wandered off along it. 

Others were more circumspect and noticed a path over a huge stone stile that seemed to offer a route to the top. This was taken.

Clearly we had split in two. A few telephone calls later we were content that everybody would end up in the same place and we carried on.

Reaching the top one of the group spotted some holes in an oak leaf.

Photograph: David Williams

These were feeding signs of the case-bearing moth Coleophora flavipennis. Diligent searching of the tree on which the leaf was found revealed the larva tucked in at the base of a leaf bud in its case.

Photograph: David Williams

Passing through an area of conifers we caught a glimpse of The Wrekin.


One of the conifers had taken a tumble and the opportunity was taken to examine it and, lurking on its bark, was a 2-spot ladybird with beads of condensation (or melted frost) on its elytra.

Photograph: David Williams

Nearby a clump of bramble was beaten and out fell this…


I am no good at identifying a bug from its underside, so it was flipped over to reveal that it was a rhopalid bug,  Corizus hyoscyami.


And passing a final seat one of the group found it just right for a little reflection on the day's events.
