Splash!

It's usually the first sign you have stumbled by a Beaver. The splash is I think a warning to others of its clan made by slapping its tail on the water surface, and then it dives. If you are lucky it will re-appear on the surface shortly, but sometimes that's all you'll get and it will disappear.

Spot the Beaver!

For a large animal Beaver can be very hard to see. This one had done the tail slap and it took me a good ten minutes to re-locate it, statue-like in the shallows. It did eventually show off by having a bit of a swim around in front of us.

We went back yesterday as Louise was keen to see one again. It wasn't the only creature making a commotion in the water as a huge Atlantic Salmon Salmo salar launched itself out of the water just in front of us, spectacular. 

It was an eventful evening with many Daubenton's Bat's swirling about us, a Roe buck barking as we disturbed him from the undergrowth. On the way home over 100 Red Deer crossed the road in front of us. 

This was the second time I'd made an evening visit to this spot recently. The photos were taken a week earlier when I took a friend there. That had been an exciting evening as before seeing the Beaver I finally got to see a live Pine Marten. I'd promised myself that I'd find my own and not go to a feeding station. Even though Pine Marten are seen by our neighbours every now and then these are not easy animals to find. No photo as it disappeared as quickly as it had appeared in front of us, posing for just the second needed to get it in the bins.

That had been the finale to an excellent day in the field. It had been a butterfly bonanza at Invergeldie, the sunny but windy afternoon conditions enabling many photographs of fritillaries.

 The afternoon had also produced Geotrupes stercorarius which I was pleased to see.

Earlier in the day we'd gone up to the community woodland to look at the orchids and bumped in the first Narrow-bordered Five-spot Burnet of the year.

 With my P-SL I seem to be going backwards as often as forwards with the species list. The two species added above were negated by the removal of Male Fern (reading indicates this is a much more difficult identification than I thought) and an Anthomyzidae, Anthomyia pluvialis was not proven.

However, a good deal of botanical learning is leading to some more species being added to the community woodland list and to mine. I now have a copy of Stace on order which will hopefully improve my understanding.

Today was a very good moth day. Lights set last night and three traps running in our small garden led to 68 moth species and a few non-moth bits and bats. Included in the 68 were Barred Grass-veneer Agriphila inquinatella and a couple of Rustic, which surprisingly I hadn't previously recorded.

Not the prettiest of moths either of these, and the list included some very attractive species.

 However, the best was yet to come as late in the day I checked the pheromone traps.

This one nearly escaped as it wasn't in the trap but under the rain cover, fortunately it fell in the trap when I touched it. 

Buff Footman, an excellent find.

Welsh Clearwing

I've used the lure for Welsh Clearwing many times with no success, until bingo! There are very few Scottish records of this species so another excellent record.

Buses

The previous post mentioned the beetle Glischrochilus quadripunctatus. Initially, I found this species in a vane trap, deceased, it has 107 records on the NBN so not a common beastie. I've been checking the vane traps at the community woodland at least once a week, but sometimes daily. The next time I looked in a trap there was another Glischrochilus quadripunctatus but this one was alive. I fished it out and released it. Then yesterday the same again, a live Glischrochilus quadripunctatus in the trap, fished out and released.

Glischrochilus quadripunctatus

A few days ago we went for a walk near Callander. The forecast was for a fair bit of rain so a lowland ramble seemed like the best plan. We set off on the Bracklinn Falls Circuit, and as I'm sure most folk do went to the falls first. Fortunately Louise and elder daughter were not marching at pace and so I had time to meander and look at moths and plants along the way. The moth Elachista argentella was seen and photographed early on, a tick.

Further along the way, in what initially appeared to be the boring forestry section of the walk, I found Micropterix calthella and more interestingly Micropterix aureatella a species I have seen only a few times previously.  

Micropterix aureatella

 It was the walk back down the hill on the road that proved most interesting though. I scrutinised the verge and very soon came across a Greater Butterfly Orchid.

Greater Butterfly Orchid Platanthera chlorantha

I then found another which was either this species or its relative P. bifolia, the flower was not yet open. Better was to come, as amongst the many Heath Spotted Orchids I found Heath Fragrant-orchid Gymnadenia borealis, a species I had been very much hoping for back at the community woodland, it was listed but not recently located. Of course, years ago when I lived in SE England and there was just "Fragrant Orchid", before the split into three species, it was a familiar plant, that one is now Chalk Fragrant-orchid Gymnadenia conopsea. 

Gymnadenia borealis

 Following this I then came across a large clump of Marsh Lousewort, a plant also on the community woodland "wanted" list, a species I know I had seen in the past, but I just could not remember where and when.

Marsh Lousewort Pedicularis palustris

That same day, in the evening, there was a Weekly Wander with a botanical theme at Comrie Community Woodland (CCW) https://www.facebook.com/groups/comriecommunitywoodland. So, on return from Calander I  hurriedly sorted myself out and headed out to the CCW. I arrived early so headed up the hill to our transects to check a few plants out for the Weekly Wander leader and participants... and bumped into Heath Fragrant-orchid just a few feet from the top of one of our transects.

Gymnadenia borealis

 Light trapping in the garden on 13th June had not been especially productive, just 16 moths of twelve species from three traps. The night was saved by the Four-dotted Footman which was NFM and an uncommon moth in this vice-county.

Four-dotted Footman Cybosia mesomella

Back to the Weekly Wander. Having shown folk the Heath Fragrant-orchid we started to find a lot more butterfly orchids, most in the process of opening, and then a couple of Twayblade. At this point a moth landed on a participant, Four-dotted Footman!

Four-dotted Footman Cybosia mesomella - again

The last of us left the Weekly Wander quite late, around ten, and the midges were starting to become savage. As I walked down the hill something caught my eye. A bright orange insect was whizzing around just above the height of the grasses. I didn't have a net, but I was wearing a hat! A carefully timed swipe produced Gold Swift. 

 

 A couple of days later I was wandering around CCW when in a spider's web I spotted this - 

Gold Swift wing Phymatopus hecta

 And then the following evening I found 12 roding males as I walked elsewhere on the site. (And also bumped into the sought Marsh Lousewort.)

 Last year I was successful in the garden with Lunar Hornet Moth pheromone lure. This is a lure to use sparingly as this is a fairly uncommon species with just 86 records in Scotland from 2000 to 2024 (Leverton & Cubitt 2024). (Pheromones may disrupt the breeding of sensitive moth species.) I tried the lure up at CCW but was unsuccessful. A new lure was purchased ready for this season and deployed with a good result on 23rd.

Lunar Hornet Moth Sesia bembeciformis

I removed the lure. However, I have other lures running at the CCW, including MOL not far from where the lure for the Lunar Hornet was deployed. 

The following day I went up to the CCW again to check all the traps. In the MOL lure trap was this...

Not the best photo as it was very active, but another Lunar Hornet Moth (clearly a different individual).

P-SL controversies

There's a recent post here - https://uigboy.blogspot.com/ which is interesting, somewhat controversial, and I have pondered the same thing. I commented rather long-windedly! I have thought, but not previously dared to voice a similar opinion.

There are a good few species which quite a few P-SL folk list but which are the very devil to identify properly. These include: various moths but particularly Common and Lesser Common Rustic Mesapamea secalis and M. didyma which can only be separated by dissection. Yponomeuta moths are also very tricky, and Y. padella, malinellus and cagnella, can only be identified from larvae found on their identified food plant or adults reared from larvae found on the identified food plant, these cannot be identified any other way (not sure about genetic analysis) (and some references indicate that this may not be 100% reliable). So don't go trying to ID the ones in your light trap to species ;-) 

Mesapamea didyma, demonstrating how the external appearance of the adult is no guide to which of the two species this is.

Spiders, these are not easy! Even though I have Roberts. There is now a very good website, - https://araneae.nmbe.ch/ I have 40 spiders and other assorted archnids on my list. I briefly worked on opiliones professionally, a long time ago. Fairly recently a spider expert I spoke to suggested that there are only around 30 spider species that can be reliably IDed in the field. (I still have some qualms about my Pirata piraticus tick...). 

There are also all sorts of other things, including stuff you'll see a lot, that are next to impossible unless you are an expert. Eyebrights Euphrasia spp - there is a whole book on these, and everything is complicated by hybrids as well, my advice; don't even think about identifying them! In Orkney, there are some endemic species of plants, but they are not on my list because I have no idea how to determine them. And then we come to the Hieracium species, brambles and dandelions.... Hundreds of micro-species, hybrids and various other impossible-to-ID things. 

The trick is to know what is possible and what is not. And that is very much a personal judgement. What is important is to be able to make that judgement. Personally I prefer things with legs and wings, but I'm quite enjoying botanical excursions this year and so slowly learning more about the complexities of plant identification.

And then there is the being shown something, but not actually being able to ID it. I don't tick these which includes various mosses in particular.

However, to be honest, I have 109 fungal species on my list and 54 lichens. I have limited understanding of these taxa and the difficulties of getting them to species, despite previously working in a lab' where we did identify some fungi (and bacteria). The ones on my list were usually identified by using AI followed up by using the quite a few books that I have and consulting online resources. Until now I've not examined spores to confirm these IDs, but I do now have a quite decent compound microscope (unearthed in a local 2nd hand shop - thank you Remake). This coming autumn and winter I will be chasing some of these up to check them further. For the moment the IDs stand. (Although it is worth noting that the whole world of fungi is in flux and I've come across quite a bit of different opinion about what is an identifiable species and what are regarded as species aggregates or groups.)

Triphragmium ulmariae - confident about this one.

The very, very good thing about P-SL is that it positively encourages citizen science and the recording of our wildlife. Whether you use iRecord (recommended) iNaturalist (ok), Birdtrack (very good for birds) or any of the various other apps and sites, recording things is good. Where there is accurate verification of records it is even better. 

Personally, I especially like recording particular sites, many of my recent P-SL listed species come from either my garden or our local community woodland where I am working on developing as comprehensive a species list as possible. This is my primary motivation, although I do enjoy the wee jousts and struggles in the lower echelons of the P-SL listing community. As a birder I was very much interested in my patch-birding and certainly in the last 20 years or so had very little interest in chasing rarities.

One of the main drivers of the Pan-Species Listing movement is Graeme Lyons. Graeme is a professional ecologist and has published an interesting book about P-SL  

I have huge admiration for anyone who has the energy and application to get any book written, let alone published. This is a motivational and useful book. My grouse (but which one?) with Graeme is his anti-AI stance which IMHO is a bit elitist. Yes, AI does use a lot of data (= energy), so is anti-environmental in that sense. However, for those of us with too much required memory for our RAM capacity it makes P-SL possible and allows us access to a world we would otherwise find pretty much impenetrable, or take up more time than we have available. Used thoughtfully, AI improves our ID accuracy and provides a useful checking tool. Additionally, as with my new found interest in vane trapping, even with an Order like Coleoptera, which I have been interested in for much of my life, there are so many families that knowing where to start can be a challenge; the key to Family is not the easiest. Obsidentify is usually pretty reliable in getting a particular animal to Family and thus providing a reliable starting point for work with the microscope and key (Mike Hackston's online keys are very good if you don't have the four volumes of Duff). There is an interesting piece on AI and identifying insects here - https://www.royensoc.co.uk/antenna-50-1-ai-powered-species-identification/

Glischrochilus quadripunctatus - fished alive out of a vane trap yesterday.

The above is nationally a quite rare beastie - https://species.nbnatlas.org/species/NBNSYS0000024510 This one is my second of late which is an encouraging indicator on the health of our woodland. And I would probably not have started vane trapping but for the motivation of P-SL.

Each to their own is my view, but whilst we might all try to push the boundaries of what is possible in the determination of particular specimens to species on occasion, being aware of ones own limitations helps.  It is fine to admit defeat, I do frequently. Sometimes after investing a couple of hours in an ID I realise the outcome is not going to be reliable. A recent tussle with Fannia sp being a case in point and a particular Tipula sp lingers in the mind!

However, sometimes the hours pay off with an ID I do have real confidence in, and all of this is a learning experience. What will the next trap emptying bring? New species or a now confident identification in moments of something that a few weeks ago took six hours (well it was an Epuraea....). 

 

Parabeckerias obtusinervis - quite a challenge, but using Mike Hackston's key to Pipunculidae backed up with the freely available, if ancient RES key (Coe R.L. 1966) I got there eventually.

 Addendum - The comments section in the blog mentioned at the beginning now has some interesting comments about how P-SL began. There are also suggestions that originally it was thought that an identification to genus or even just to family could be "counted. Personally, I'm pleased that we have to identify to species, records to genus or family are of little value IMO.

Meall Corranaich

I'm not a great one for going up the hill, not unless I have a very good reason to go. However, on this occasion younger daughter was visiting and no one else was available for transport duties or accompanying, so it fell to me.

The weather was perfect, sunny, but not too warm. And I did need to recce for later in the season when a botanical expedition to Ben Lawers will be required.

This was a pretty gentle wander for me. Younger daughter strode off into the distance to tackle Beinn Ghlas and then Lawers itself whilst I took the left hand path and headed for the col between Beinn Ghlas and Meall Corranaich.

An Stuc in the distance from the col (Ben Lawers is hidden)

 This was very useful in terms of seeing how feasible it was to drag myself up and by Ben Lawers to search for plants in July. Good to find I don't have to hack up Beinn Ghlas, but can by-pass that obstacle.

Anyway, having watched younger daughter disappear into the distance I ambled along the path to the col. There were many, likely hundreds, Ctenicera cuprea flying around.

Ctenicera cuprea

A few carabids scuttled away beside the path as I walked; annoying. But then something caught the eye. Several expletives, as although having only seen this beast once before I knew it immediately...

Carabus nitens - wow!!

This is really not a very common beetle at all. I had it in a pot for a few minutes and showed it to a couple who were heading down the hill, they were suitably impressed.

After a bit of a chat, the folk headed off, I released C. nitens and ambled on. And within a couple of minutes was looking at a second Carabus nitens!!! Now Ben Lawers is a pretty special place and it has an impressive list of rare and wonderful wildlife but that was exceptional.

I had brought the "wrong" cameras with me. I regretted leaving the EM-1 with the 60mm macro at home. I'd brought a longer lens and the wee Olympus Tough TG-4. In the bright light I was struggling a bit. However, the Tough came into its own at the col where there was a very interesting shallow pond (which I failed to photograph).

This was the day I finally decided I could tick Pirata piraticus, with this one hunting on the water's surface. 

Pirata piraticus, the Jack Sparrow of spiders.

An advantage of the TG-4 is that you can stick it underwater. There were lots of interesting things there including two different caddis larvae, several beetles and species of Corixidae which may prove to be identifiable.

Two very differen caddis larvae

I'm not sure if there is a resource for the identification of caddis larvae by their cases, I presume there probably is. Alternatively the FB Group may be able to help.

Beinn Ghlas, Ben Lawers and distantly An Stuc from the top.

I investigated a snow patch, but there were no accumulations of insects.

Way off

We then decided to go off via an alternative route. I wouldn't necessarily recommend doing this but I had checked it out on the way up.

There was less to see as we went down.

Red Deer

Red Wasp Vespula rufa near the top surprisingly.

There had been lots of  Bombus monticola Bilberry Bumblebee, but I failed to get an image.

And then, last week I did it all again, not so nice weather, a bit of a brute of a trudge up and fewer things to see, although I did get a couple of lichen ticks on Meall Clachan, the hill behind Killin.
