Up/Down

Well, I'm here and alive enough to post - always a good thing I reckon. My surgery did go ahead on Weds 15th June, though I knew nothing of it until being brought out of sedation and off of a ventilator on 16th morning which probably helped with managing the pain a bit. I spent the first day in intensive care, just about getting over the anaesthetic whilst developing a morphine addiction. On Friday I got moved to a general ward, and spent the next three days gradually becoming more self-dependent and mobile. Much to my surprise and relief, on Monday 20th they muted that perhaps I could go home early (fully expected a 10 - 14day stay) as long as I came back in for a couple of check ups on the Weds and Friday - I didn't hesitate in imploring them to make it happen. I hate hospitals at the best of times, but being in there once you are actually mobile and looking after yourself is absolutely the most soul-destroying and mind-numbing thing imaginable. So on Monday night I was home and happy.

Tuesday 21st June was a nice warm sunny day so I was pleased to be able to intersperse sleeping, relaxing and generally lounging about with forays into the garden for fresh air and to watch a few insects on the border flowers. It dawned on me that with the sun shining, and with it requiring virtually zero effort, I could dangle a couple of lures. So I tried both VES and FOR with success, one Orange-tailed Clearwing to the VES lure and x3 Red-tipped Clearwings to the FOR lure. I wasn't up to fannying about with a camera though so only managed a couple of crappy phone shots ....

Orange-tailed Clearwing

Red-tipped Clearwing

I think the adrenaline of seeing clearwing and the euphoria at being home overtook common sense, and I put the moth trap on for the night. Surgery and being in hospital screws up your sleep pattern for ages so getting up early to empty it wasn't a problem, though it was a bit more physical effort than was perhaps good for me. Nothing exciting in there, but it was looking sunny again so out went the LUN lure despite it being perhaps a bit early for the target. By 08:30 there were x2 Lunar Hornet Moths in the trap. All the more excellent as with the pre-surgery records of Currant and Red-belted, all x5 clearwing species that I recorded here last year have come again - no flash in the pan luck involved, all clearly present within close enough proximity to come to the lures reasonably soon after deployment.

Lunar Hornet Moth

Again, the moth trap went out and again with some effort I got it done early in the morning. This time though there was excitement, a new for garden macro and a decent migrant that warranted a quick snap with the camera ....

An expected addition to the garden list with recent expansion in VC55 range, shame it was a bit tatty.

Bordered Straw - second garden record after one in 2006

The moth trap went out again on Thursday 23rd June, back to standard fare and by now I was thinking that I'd perhaps overdone it, so the trap got put away as the weather faded a bit anyway.

A week or so after surgery, things can go two ways. You either feel like you're getting somewhere and feeling a bit stronger each day, or you start to slide and feel a bit crapper. Over the weekend I felt a bit lethargic and lacking energy, and on Monday I was in incredible pain in my left kidney. Back to the hospital to be checked, and I ended up being re-admitted with bloods showing infection markers. A subsequent CT scan showed a build up of likely infected fluid stuck in a pocket somewhere in my pelvis, which would require draining under a radiologically guided procedure. By then I'd had a couple of doses of IV antibiotics and was feeling fine again, but the NHS system conspired against me and despite my protestations and moaning I ended up being stuck back in there until the Friday evening whilst they tried to work out if/how/when this would be done. I was absolutely exasperated; every day I was nil by mouth from midnight to c4pm just in-case they managed to fit me into someone's schedule, whilst being sedentary and having bugger all to do. On the Friday I made it clear I'd had enough and I was seriously on the page of walking out and self-discharging, luckily they'd already come to the conclusion and seen sense that they were better off bending their own rules and essentially discharged me without discharging me, so that I could go back for the procedure at an appointed time as a day case.

Back home for another week, gradually building myself up again after going backwards in hospital. Yesterday I went in for a CT Guided Drain procedure - and by christ it was the most painful experience of my life, local anaesthetic only works so deep, and to avoid any remaining organs or major blood vessels they went in the most direct route - basically they skewered my backside and it fucking hurt! Anyway, it's done now and I can get back on with recovering (although the drain will of course have to some back out, which will also be uncomfortable but a lot quicker!). I'm actually feeling a lot perkier now and I'm okay with basic pain relief. I've got a long way to go with recovery but feel like I'm on the right path now.

Having major surgery, losing body parts and being in pain or uncomfortable etc is of course worth it if it means I'm still here for the foreseeable, watching the kids grow up (metaphorically, they've already grown up physically), being here for and with Nichola and contributing to society. The surgeon told me last week that the histology on the stuff they removed has clear margins - that should mean I am cancer-free and there will be no further treatment. I'd really like to hear that again with Nichola by my side at a formal post-surgery consultation in due course.

The trap will be back out tonight, I've missed some of the best mothing weather for ages and feel like I need to get back on track. I'm also able to sit at the desktop PC for a while now - hence posting. 

I realise that a lot of this post is a bit self-centered and unlikely to be of any interest to anyone, but as I'm sure I've said before I write this blog for me first and foremost.

In other news, apparently a large number of MPs in the lying bastard party with no integrity and morals have realised that their leader really is a lying bastard with the integrity and morals of a pile of bat guano. Who knew!

I really like this new track from Simple Minds ....

Temporary Silence

Today we said farewell to Adrian at a very calm and celebratory ceremony, with wall to wall sunshine outside and a strong attendance. It was good to see a few faces for the first time in a long while thanks to Covid etc, but clearly not in the circumstances we wanted to be meeting.

That should have been the toughest part of the week, but it isn't. I'm not going to lie, whilst I've been putting on a brave face and fronting things for a while now I'm pretty apprehensive about what's coming.

My life has been a rollercoaster since early 2019 when I was suddenly very ill indeed, got diagnosed with rectal cancer and since then I've had three separate operations, two different lots of radiotherapy and two lots of chemo. The last surgery in October 2020 was radical and life-changing - I've not spelled it out before but I'm sure some realise that I have a permanent colostomy with absolutely zero chance of reversal. You'd think by now I'd be over it, but it seems that all of the treatment and surgery so far is not quite enough. My cancer is starting to come back - right in the place where it would have been before having body-parts removed. Thankfully for now at least, there is no sign of any spread; whilst it is a pretty resilient cancer it doesn't seem to be malicious enough to try and finish me off. Not just yet at least. So I have another shot at getting rid of it for good, but this time I am facing even more major radical surgery and at the end of it I'll be pretty empty below my navel - no bladder or prostate, but helpfully I'll have another bag to balance me out ....

I've come through surgery and just about got back to as near a normal life as possible. I've not been as constrained as I may have been, and I've been able to enjoy stuff like festivals, gigs, West End shows, football matches home, away and abroad, beers and curry and - not least - getting out and about to enjoy nature when time and weather allow. I know I will do all that again, even though it will be tough again, but that doesn't clear the nagging doubt in the back of my mind about what if this doesn't work. 

I'm not planning on going anywhere any time soon though, and certainly will not be going without kicking and screaming. But you can expect this blog to be quiet for a while. I go for surgery on Thursday and am likely to be in the hospital for a couple of weeks, and then I am back at the start of the long road to recovery again. Whilst I'll be trying to get back connected to the world asap, I doubt I'll have anything to post for a while. But of course as soon as I can, the garden light and pheromone traps will be out again so you never know.

For now I'll share this one, a beetle that has few VC55 records and was a complete surprise in my garden pheromone trap this afternoon (with FOR lure deployed hoping for Red-tipped Clearwing). This is Triplax russica - new for me, and perhaps just the fifth or sixth for VC55 (four reliable records, a possible fifth, last in 2005). Excuse the moth scales that it has picked up whilst having a jolly time in the pheromone trap.

Life on Slate

Back to yesterday: after leaving Burbage Wood I headed along the motorway north straight to Swithland Wood southern car park. If I was going to have any luck with pheromone lures for oak spp. this was as good a place as any. Immediately as I got out of the car I noted the masses of Great Wood-rush and had a quick nosey. Within a meter of starting I found the mine I was looking for ....

Elachista regificella

There is so much of the stuff here that I imagine sweeping at the right time would easily yield adults, rather than trying to rear through.

I headed into the wood to the big slate mound and biggest quarry in the middle, and deployed the pheromone trap in anticipation. Whilst waiting, I noted masses of Adela reaumurella dancing around the oaks, all too flightly and quick to grab a snap. I also thought I'd look at some more leaves and add a couple of Eriocraniidae to the list for the day. Dyseriocrania subpurpurella was decidedly easy, and especially so compared to the earlier effort on hazel! Birch mines were not quite so easy to fine, but I found a few. Eriocrania sangii is easy enough due to the dark larva, the others though are not so straightforward. The mines I found could only really be E. semipurpurella or E. unimaculella, and the couple of larvae I checked match Eriocrania semipurpurella. Not that I managed to catch a useable snap, but the lack of darkened prothoracic spots noted.

Whilst mooching about, I also found a large gall on oak ....


This is from the sexual generation Oak Apple Gall Wasp (Biorhiza pallida).

I also found a couple of tortrix larva in leaf rolls that I've not made any attempt to identify as yet ....


Back to the lure, nothing. But I did notice a load of Navelwort that I don't remember noticing in VC55 before (though I probably ignore it as I see it so much in Devon), with a much more interesting looking bunch of plants around that I didn't recognise at all. I grabbed a few snaps, figuring it would be easy to work out subsequently, but couldn't come up with anything other than Wild Candytuft - which didn't look right and would be unlikely anyway. I enlisted some help, and got work back from Geoffrey Hall (Botanical CMR) via Graham Calow that it is actually Shepherd's Cress at its only known site in VC55. Appears I stumbled on an even more unlikely plant!

Navelwort

Shepherd's Cress (Teesdalea nudicaulis)

Back to the lure again, and nothing in the trap but some movement caught my eye and I noticed what appears to be a small pale tortrix perched on a leaf. A deft bit of potting and it was secured. I'm wasn't convinced it was attracted to lure, and after scrutiny I'm even more convinced as I think it is actually a worn female ....


I'm pencilling in this as a female Pammene argyrana, and hindwings seem to agree but I'll get it chopped at some point.

Not quite what I was hoping for, but a casual jaunt around a slate mound turned into something productive anyway.

Oaky

Apologies in advance for yet another update on pheromone luring around oaks for Pammene giganteana. Pretty much every day this week, I've nipped to a spot somewhere on the way home from work and added dots to the map. I also headed out for an hour earlier today a bit further east in the next hectad. With these records, and the couple from last year, I've recorded this now in 13 tetrads. My success rate with the lure is around 87% - and where I've not been successful I think that conditions and/or time of day are factors.


In the following maps, the bright green dots are 2022 sites and the blue dots are the two 2021 sites.

SK50

SP59

SP69

I know that Graham Calow has been recording this in SP49 (as well as the four squares in SP59 around Frolesworth and Leire), and I think Adrian Russell will have added some dots to the east of Leicester.


It still seems amazing how the perceived status of this species prior to the use of pheromones was so completely wrong. Very few records to light, and no casual daytime records. There are similarly 'rare' species that may prove to be similarly common later this year. We added Pammene suspectana to the VC55 list last year, but there were no widespread efforts made to record it and I am certain it will be common. Pammene splendidulana, Pammene albuginana and perhaps Pammene ignorata and Pammene obscurana could all go the same way. Pammene argyrana may also prove to be more common and widespread than existing light trapping records suggest.

On Sunday afternoon, whilst I was out at the KP watching LCFC win, I speculatively left the MOL pheromone lure in the trap out in the garden. I put it out at 13:00, literally just before I got in the car and headed off to the game.

Here's a very sketchy map: the blue dot is home, the green dots are definite oaks that I know of that are closest to home, and the orange dots are a large tree that I think is oak (I can't get close to it and I've never bothered trying to look at it to see, but looks like it 'naked' from the lane) and an area on Whetstone Golf Course that I think has oaks (again to be checked). The green dots to the SW of home are those at Victory Park (see last post). There are almost certainly more oaks within this image than I can recall. Either way, as you can see there are oaks dotted about reasonably close to home (within 1km) but it is not exactly abundant.


I had no expectations, but with good sunshine, a bit of warmth and a light breeze it was as good a time to try an any. I got home at 16:30 and headed straight to the garden to check the trap. Well, blow me. x2 Pammene giganteana were within it. I am 100% certain that these are completely unrelated to the use of the trap on Saturday: the one I took to photograph was still in the fridge, and had there been any inadvertently taken into the car they would have been buzzing around the trap on the passenger seat for sure. It's perhaps not an entirely unexpected garden tick, as there are plenty of similar experiences being posted on the 'Pheromone' Facebook group of garden records. This was considered a rare moth in VC55 before last spring, but it is clearly quite common - just inconspicuous and perhaps poorly attracted to light traps.



post-script: whilst I was writing this I'd left out my new ARG lure (intended for Pammene argyrana) in the garden for the last hour of daylight. I checked just after posting - another x2 Pammene giganteana, so they're clearly not coming from too far away!

I had to nip into work yesterday late morning, so whilst out I briefly stopped off at some of the large open parks that are local to my workplace and home with the MOL pheromone lure. This lure is specifically intended for Grapholita molesta (an orchard pest and non-native non-naturalised species that is not likely to be here, not yet anyway) but like many of the lure it has turned out to be very useful for attracting other species within the Tortricidae. This one is excellent for Pammene giganteana as I saw last year, albeit a bit later into the flight period.

Conditions were certainly not perfect, as although very sunny and reasonably warm the wind was absolutely blasting in persistent gusts. Nevertheless, I tried at four locations and within a few minutes at each I'd added four dots to the VC55 map which I expect will be filling out quite widely over the next year or so.


All four locations are open parkland with large oaks, but none are 'oak woodland' - in fact none are really woodland at all with large open space around the trees and at the Cosby park the oaks are actually within the boundary scrub alongside a road with housing on the other side.

Western Park

Braunstone Park - northern end

Braunstone Park - southern end

Victory Park - oaks in boundary on eastern side

This one on the trap at Victory Park ....

.... and one potted up at Western Park for a proper shot

With the wind blasting, I managed to hand the trap from snags on the bark at most of these sites and in the process found a number of resting Diurnea fagella and Luffia lapidella (f. ferchaultella) at Braunstone Park. I shall try and get out with the lure again before the end of the month, targeting similar large parks and large mature oaks.

Meanwhile the garden trap has been out the last couple of nights, no big numbers but it's starting to wake up a bit. A couple of different Twin-spotted Quakers is nice for the garden; it has never turned up in numbers here, usually one or two a year at most and it wasn't annual but this is now the fifth consecutive season it has turned up.

Simply Red

So far this evening, I've had a very productive time sorting photos from the trap and working through a number of gen det confirmations - essentially adding several species to my PSL and my garden moth list at the same time. But I'll save that for another day.

You may recall that last weekend I unexpectedly added a couple of clearwings to the garden list. Since then, I've tried on a few days in the week with the MYO lure for Red-belted and the FOR lure for Red-tipped, both without success. The conditions yesterday were perfect for clearwing hunting, but I was frankly too knackered, hot and bothered to go out after the mothing expedition on Saturday night. I decided to try a couple of different lures in the garden to see if anything else might be attracted. I stuck out the VES lure again, but again Orange-tailed turned up quickly so I couldn't leave that out. I tried the HYL lure (intended for Raspberry Clearwing) but nothing was interested in a couple of hours. Next I hung out the CUL lure (intended for Large Red-belted). Within 15 minutes or so there was some action, but the small black insect darting around the trap was not going in so I swiped it in my net ....


So somehow, Red-belted Clearwing arrived when using the wrong lure - with no response to the supposed target lure. I've only seen Red-belted once before, a brief appearance to MYO but not lingering and not that bothered. Every other time I've tried MYO I've had no response. I left the CUL lure out but within another 10mins or so the trap had another two Red-belted so I pulled it in. From the pheromone luring Facebook group it seems that Red-belted is actually more attracted to the CUL lure than MYO - so perhaps I should try again at a few sites and see what happens.

Later in the day, after sleeping through most of the British Grand Prix ( I saw the first lap, nodded off during the red flagged stop and woke up with about three laps to go) I decided to try again with the FOR lure. The conditions were still perfect, and I've had success with this lure when out and about late in the afternoon / early evening. I wasn't too hopeful though and left the lure in the trap whilst I made a rudimentary effort at cleaning the dust and bird shite off of my car. An hour or so later, I checked the trap and ....


A single Red-tipped Clearwing, the fifth clearwing sp. new to the garden this year. Ironically, this is the one that I was most hopeful about!

The clearwing season is probably not going to last much longer, and I doubt there will by any others added to the garden list. Yellow-legged has resolutely failed to turn up but I can't keep leaving out VES anyway, Hornet Moth does not respond too well to the lure but will be over by now, and Six-belted is unlikely here despite being one of the commonest clearwing sp. But I think there is more to come from hanging out the lures, one way or another.

I imagine from the blog post title you were expecting me to post a link to some dirge from a ginger-haired Mancunian .... nope.

Orange Moon

Yesterday was almost ridiculous. And I don't mean the match last night ....

When I set the moth trap on Saturday night, I also left out the LUN pheremone lure in the vain hope that it would attract one or two Tineid moths (as it has done for many others). Sunday morning, not quite at the crack of dawn, I emptied the moth trap and checked the lure - nothing. By the time I'd emptied the trap it was c06:30 and I intended to get back into bed for another couple of hours or so. I simply left the pheromone trap hanging. When I was back up and in the kitchen waiting for the kettle to boil, I looked out and thought I saw some movement inside the trap .... surely not .... but I went and checked ....

I couldn't quite believe it, x2 Lunar Hornet Moths in the garden. I'd never thought of putting the lure out in the garden to target this clearwing. There is a decent sized sallow in the adjacent garden, but I'm sure these came from a bit further afield (though clearly not too far). From using this lure last year, I reckon these don't fly too early in the morning, I had no success anywhere before c9am.



Buoyed by this inadvertent success, I decided to try another lure that has not hung in the garden before - mainly because I'd seen a couple of other reports from around the VC suggesting it might be worth a punt. So out went the VES lure whilst I nipped out with the LUN lure attempting (but failing) to add another dot to the VC map.

I got back after around one and a half hours, had a squint at the trap and could not believe it - more clearwings. The VES lure was initially intended for Yellow-legged Clearwing which is pretty much a specialist of mature oaks / oak woodland. But the lure also works for Orange-tailed Clearwing which, until this year, was thought to be rare in the VC and pretty much restricted to the east of Rutland. Orange-tailed mainly feeds on Wayfaring Tree which is itself pretty scarce in VC55. I suspect no-one bothered trying the lure in their gardens in years gone by as neither clearwing species seemed likely. But Orange-tailed also feeds on Guelder Rose, and perhaps it is also feeding on cultivated viburnums. Either way, there were three in my garden and again these can't have come too from too far away.




Orange-tailed Clearwing

I tried to make it a hat-trick but the FOR lure failed to bring in Red-tipped Clearwing although the afternoon was pretty dull and cloudy. Still I can't complain with two garden ticks in rapid succession.


Otherwise, the last couple of times the trap has been out I've lazily pointed the camera at Torts on the sheet and trap body ....
