And then there was one

Pam's Pools, Underton - Wednesday 2nd August 2017

Pam's Pools is not a true description of this collection of habitats but they are the first feature you notice on arrival. The site is far more extensive than first impressions and includes hillside woodland, streams, meadows and orchards as well as the pools.

Despite the poor weather ten of us gathered in our wet weather gear on site in the shadow of a very welcoming cabin which will feature later in this report. A group photograph was called for and taken just as our host arrived on her bicycle.


A group of ten - there are only 8 on the photograph?

Well, I was behind the camera and the absentee was a late arrival.

One of the group had  a personal objective for the day and wandered off to pursue this. Here are the results of his dedication:

Eventually the initial chatter of the rest of the group died down and we set off into the woods with our host who was giving us a guided tour. However some dallied to look at fungus and other things of interest.

One of us was disinclined to climb into the woods and preferred to stay and hunt for things of interest around the pools. Having explored the woods at a recent moth event I kept him company.

As we pottered by the first pool we would hear the occasional voice from the woods and every now and again someone would appear only to disappear again. Everyone seemed content so why worry?

Time marched on and we got to lunchtime. The lure of the cabin was difficult to overcome, so we returned to it only to find three others already tucking in  to their lunches. 


As we sat down to eat ours others appeared (from different directions) to join us. No-one had said we were going to have lunch here. It just happened!


Lunch over, we moved slowly through the orchard where we a found common puffball that had teeth marks in it possibly from a small rodent.

We passed between the two lakes and then spent the rest of the day by the second pool and the meadow that bordered it.

The vegetation by the pool was visited by lots of damselflies and the occasional dragonfly. These included white-legged damselflies. I do not have a photograph of a white-legged damselfly but here are some of the other things that we found by the pool.

The pool is home, unfortunately, to the invasive signal crayfish which has devastated the population of our native white-clawed crayfish through competition and carrying a deadly fungus that the native crayfish is susceptible to. The crayfish, however, provide food for others as these remains of a head indicate.

A couple came up to me to say they were leaving and left. I carried on searching in the vegetation then two more did the same. This was fine, they are grown-up, they know the way back to their cars; I knew and checked where that the other five were still in the vicinity; I carried on.

As I climbed to the top of the meadow I did another check and found that there were only two others in the area. I was not too concerned.

I nipped into an area of woodland, came out and found I was all alone.

OK, enough hints, time to go. I wandered back to the cabin and found all bar the first two milling about the cabin!

Some time later we all made our way home.

My thanks to Pam Yuille for giving us permission to visit her site and do what we enjoy doing and to the photographers Les Hughes, Jim Cresswell, Bob Kemp and David Williams for providing the excellent photographs.

A Tortoise in the tale

Rough Park and Dale Coppice - Wednesday, 26th July 2017

Whilst most of us lucky enough not to have to go to work may have peeped out of the curtains early in the morning, seen the rain coming down heavily and decided to have a lie-in and stay dry, half a dozen of us met undeterred at one of the access points to Rough Park.

The rain had abated by then but everything was soggy. Sweep nets were out of the question as one sweep would result in a useless very wet net. Eyes, beating trays, and towels were the order of the day, though spiderman insisted on taking spidervac.

The short path that we took from the cars to the park was bordered by a line of trees including oak and acers. Eyes came in useful here as we inspected leaves for galls, leaf-mines and, of course, the egg-sac of the sputnik spider - Paidiscura pallens.

Oak is the host for many gall causing insects. Amongst those we found were silk button galls on leaves caused by the gall wasp Neuroterus numismalis.

artichoke galls in the leaf buds caused by the gall wasp Andricus foecundatrix.

and knopper galls on the acorns caused by the gall wasp Andricus quercuscalicis.


A couple of the group dived into the trees and emerged a few minutes later clasping a huge mushroom - 


This is Boletus radicans. If you bruise the gills they turn blue. As you can see from the following photograph this was tried many times (some may have been natural damage)!


Eventually we made the entrance to the site and made our way along the path through the grassland that is Rough Park.


The grass and trees were still very wet from the rain so spidervac was fired up. Whilst some of us inspected the catch from this device others used their eyes and cameras.

Time was pressing, i.e. it was lunchtime. We headed for a seat which turned out to be close to the entrance to Dale Coppice.



 As shown by the post just beyond the gate in the background of the above photograph


Some sit to eat lunch, some stand and some wander about. One wanderer found a nymph of a bronze shield bug on a bramble leaf


Lunch over we headed into Dale Coppice. The path plunged downwards. We came across several trees covered in fungus resounding in the evocative names Dryad's saddle, lumpy bracket and dusky bracket.



Lumpy bracket is lumpy but it is often covered in a green algae as it is here


On through the coppice we meandered until we came to a lane. Following the lane along the edge of the wood we came across the newest habit to grab our interest.


Vegetation in the middle of the road! Someone has to do it.

Our travels through the county take us along many minor roads where lack of regular traffic and the accumulation of soil allows grass and other plants to grow in the middle. Often there is just a hint of green but sometime there is short grass and very occasionally longer grass and other vegetation. As we drive along these roads our thoughts wander to "What lives there?" Well, there is only one way to find out and that is to look.

This was our first try. Spidervac was employed on the above patch and several others. We had results! Spiders (not sure which species they were) and a ground bug Drymus brunneus. I have know added this habitat type into my records! I look forward to more opportunities to investigate. If you know of this habit near you let me know.

Pressing on we followed the lane to its end, then a path which opened out onto Rough Park. Looking around this area we found the labyrinth spider Agelina labyrinthica

Here is something closer to an insects view of the spider

The heavens opened. We were as far as we could be from the cars so we sought shelter.

The rains stopped. We made our way into the patch of heathland in the middle of Dale Coppice.

The heath is on quite a slope but we managed to stumble to the bottom where we set up camp and then went about exploring the area.

A snail-killing fly, Coremacera marginata, was spotted and photographed.

A common green grasshopper was tracked down

Someone noticed a blue bug nymph which was feasting on what looks like a sawfly larva.

A further shieldbug grabbed our attention. Actually our spiderman grabbed the bug! A small grass bug nymph. As you can see its treatment caused it no harm.

Photograph: David Williams
Time to return to our cars.

We clambered out of the heathland the way we came and as we were crossing the grassland to get to the path our orthopterist with much younger ears than most of us - and a bat detector - announced that he could hear Roesel's Bush-cricket.

"Shall I try sweeping for it?" asked the Great Stick Finder (see "A Forgetful Day" - 7 May 2014).

"Yes."

So he swept.

He did not find the bush-cricket but he did find this

Photograph: David Williams
A tortoise shieldbug. What a find. I was beside myself.

It can be found in the Wyre Forest but apart from one record from Dolgoch Quarry a couple of years ago it has never been found (to my knowledge) anywhere else. It has now cropped up in Telford. It must be elsewhere, so please keep a look out for it.

By the way the sun was shining by the end of our outing.

My thanks to Severn Gorge Countryside Trust for permission to survey in Dale Coppice, the photographers Bob Kemp, Jim Cresswell and David Williams for allowing me to share their photographs and those who braved the weather to make this another memorable day.

This is a true story

"Bagbatch", All Stretton - Sunday, 23rd July 2017

Arriving for our second visit to this site this year we were met by two moth trappers. They had trapped the night before and had just finished going through the catch. Thus, the first 10-15 minutes was taken up by looking at what they had found.

Inspection over we got ready and eventually we left the car parking area. On our last visit we took a circular route around the site in a clockwise direction. So, this time, for a change we started out on a similar route but anti-clockwise. You cannot say we are not adventurous.

We walked about 40 yards into the first meadow then set up camp there staying for about the next 45 minutes. We set a fast pace.

An early find in the bramble at the edge of the meadow was a mid-instar Green shieldbug nymph.

And on some water in the vicinity a pondskater provided a wonderful subject on which to practice photographic skills.

Pretty impressive - and no need for Photoshop.

Having scoured the field and its surrounding vegetation I realised that if we did not move on

1) We could be having lunch within 40 yards of the cars;
2) We would never get around the site.

We moved into the next meadow which was smaller, wetter and with a good variety of vegetation of different heights.

Knapweed in this area was proving particularly attractive to the tachinid fly Prosena siberita.

These reports rarely include any photographs of flies other than hoverflies and craneflies so I am pleased to be able to include this one and a few others that will follow. Flies are all around us and, although sometimes unwelcome such as horseflies and mosquitoes, make up a major part of the fauna and should be enjoyed.

A couple of other finds to report, then .... guess what? 

A comma proudly displaying its comma marking on the underside of the hind wing.

And a harvestman Nemastoma bimaculatum.

Have you guessed?

It's not hard.

Lunch


Satiated we moved on. We still had about 90% of the lap to go.

We entered an area of longer vegetation and woodland as the path bordered a stream. Of passing interest were the long-horn beetle Rutpela maculata.


This is a regular in these reports and is always a delight to see.

Another fly! And another tachinid - Macquartia praefica.

Photograph: Nigel Jones
And a cuckoo bee - Bombus barbutellus

Photograph: David Williams
The hymenopterists in the group got quite excited by this find, so I assume it is unusual to see it in these parts.

Cuckoo bees follow the example of the bird they are named after, that is, they take over the nests of other bumble bees. This cuckoo takes over the nest of the Garden bumble bee Bombus hotorum.

At this point I saw a plant that I thought was cowwheat, so the heavy gang were called in to look for the Cowwheat shieldbug


The shieldbug was not found.

Not surprising really, the plant was greater stitchwort!

A new member of the group wandered down the path.


It joined us as we ascended through the woodland to the next meadow then decided it had had enough and settled down to rest.

Emerging from the wood we entered a wonderfully flower rich meadow with glorious views of the hills


This area held our attention for most of the afternoon.

What about the rest you may ask?

Well, there is always another day.

Our dipterist was especially pleased about a fly that one of the group had found.

"A very interesting conopid" I think he said.

It was. It was a nationally scarce fly that had not been recorded in Shropshire for over 30 years - Thecophora fulvipes.

Photograph: Nigel Jones
Small coppers were flitting about and one took a fancy to the picture of an Eyed hawkmoth on the front of an identification guide

Photograph: David Williams
Also found in this area was the picturesque micro-moth Agapeta zoegana.

Will you be surprised if I said that time was pressing?

It was, so we moved on swiftly through the next field, pausing only to look at a dead tree and a centipede.

Photograph: Jim Cresswell
We were about to enter the wood on our last part of the journey when a cry of "Purple hairstreak" was heard from one of the tail-enders. So we all trooped back to look

Photograph: David Williams
It was not camera shy and although it fluttered about a bit it always stayed within easy sight.

One last fly. I am not sure where this was seen but the timing of the photograph is after the one above. This one is a robber fly - Machimus atricapillus.

Photograph: Nigel Jones
We raced back to the cars only to be offered refreshments by our hosts.

How could we refuse?

So we didn't.

As we enjoyed our drink our orthopterist investigated the compost heap to look for little earwigs which ply their trade in this environment. He was not successful, but he found a pseudoscorpion which turned out to be the "Compost chernes".

My thanks to Mags Cousins for inviting us to the site, to the photographers David Williams, Jim Cresswell and Nigel Jones for generously allowing me to use the results of their craft and to the group for once again providing excellent company as well as spotting lots of interesting wee beasties.

What has the title of this piece got to do with the rest you may wonder?

If you have seen the film "Fargo" and its spin-off TV series you will know it starts "This is a true story" "The events happened in Minnesota in ..." This is untrue, it is not a true story although it may be tenuously based on some event somewhere in the world.

Well this report is a true story based on events that happened at Bagbatch on Sunday 23rd August. The key word is "based". I am the grateful recipient of photographs from attendees but am not always aware of where and when they were taken on the trip so I try to put together a plausible tale from what I remember and the photographs. 

I hope you enjoyed it!
