Light trapping at CCW

I took three light traps to the community woodland on Monday evening. 

Here's my converted Robinson in action, it has a triple wavelength 6W LED and an actinic blue circular bulb, 22W. These run comfortably all night from a lithium battery pack (a lot lighter to carry than a car battery). (I'd forgotten my plastic bowls to cover the electrics, so the box had to do, no rain forecast.)

The other two traps are Heath traps, one running a blue LED from a car battery and the other a blue actinic. Unfortunately, the one running the actinic seems to have an issue when running via a car battery and an inverter. Not sure what the problem is, the set-up runs fine from the mains. So, just two traps functioned. Fortunately the trap that failed was the one near the car, not the one way up the hill that I'd lugged a car battery to.

Closing the traps at first light, not so early now.... but there were still moths flying around the traps. I don't trap so often at the community woodland so the Robins and Wrens haven't discovered light traps as a source of tasty treats.

A good search of the outside of the traps and the surrounds led to a few moths and caddis (Trichoptera) potted to examine later.

The failed trap, which had been working when I left it the previous evening, contained nothing, sadly.

However, the blue LED held quite a few including a very nice Merveille du Jour, always a treat to see.

There were some Red-green Carpet, three in this trap and one in the Robinson.

Chloroclysta siterata

Next moths out of the trap were Rosy Rustic, three and one in the Robinson; Chestnut, one and three in the Robinson; a rather worn Frosted Orange; a total of five Pink-barred Sallow; a Green Carpet; a July Highflyer; and in the last egg tray two copper underwing sp. One of the copper underwings showed the field character of Copper Underwing Amphipyra pyramidea but the other was pretty washed out in the underwing, so retained, currently listed as Amphipyra sp.

A copper underwing, not sure if this is the identifiable one or not.

Lastly, a Green-brindled Crescent was lurking in the bottom of the trap.

 Along with the moths were various other interesting things.

Halseus radiatus, a caddis fly Tricoptera

This very interesting, tiny Hemiptera is of genus Kybos, a hopper, it requires dissection to get to species, but is probably Kybos ludus which is associated with birch Betula. There are just 4 records of K. ludus on NBN Scotland

A familiar, smelly beetle, Nicrophorus investigator, a carrion beetle

New for the woodland, and such a smart animal, Pantilus tunicatus, another Hemiptera, this time a mirid

The cranefly Pedicia occulta, there are only 29 records on NBN Scotland for this species, an excellent find

 Then to open the Robinson trap....

As well as some of the moths already mentioned, and including a second Merveille du Jour, there was an ear moth that will require dissection to determine species, Canary-shouldered Thorn, several Common Marbled carpet, Acleris laterana x2, Pinion-streaked Snout, Small Wainscot and Setaceous Hebrew Character. A big surprise was a Rush Veneer, a species usually considered to be a fairly scarce migrant in Scotland.

An ear moth Amphipoea sp

Pinion-streaked Snout, quite a small moth for something that is classed as a "macro-moth"

Rush Veneer, a very uncommon moth in Mid-Perthshire

Setaceous Hebrew Character

 In addition there were other critters, not moths, that were attracted to the light of the Robinson trap.

Rhyacophila sp - a species of caddis fly, to be determined by dissection

Sexton Beetle Nicrophorus humator with passengers, phorid mites which hitch a lift on the beetle from one meal of dead things to the next!

Limnephilus lunatus, a rather attractive caddis

So at least another twelve species for the woodland species list, with a few more to be added after they have been specifically determined. 

Given suitable conditions, a warm evening with no heavy rain, but overcast ideally, it would be worth repeat trapping latter in the week or at the weekend. Unfortunately, it may be that the warm spell has passed. After torrential rain early this morning it has now turned clear and cold. 

 

Bang, crash!!

 

Many thanks to CP for the above

We were having a cuppa and there was a huge bang. Nothing shook, but it was like a not too distant explosion. There is a firing range not too far away, so that was a possibility. However, it was shortly confirmed that this was a close-by, but not very powerful, earthquake. The epicentre was by the appropriately named Shaky Bridge in Glen Lednock, very close by. The print out from the nearby Earthquake House shows the 'quake.

Many thanks to CP for the images.

Lots of IT issues of late... our dish through which we receive our internet (a local system, not via Mr Musk) died suddenly, and took a few days to fix as the local tech' was away (many thanks to SMcK for fixing it yesterday). Now Blogger is not loading images directly, I have to save them to Google Photos in order to upload them to the blog.... 

Whilst without t'internet for a few days we found a DVD player that worked and dug out some discs we had never watched. Actually, it was rather good watching films this way. Richard II from the Hollow Crown series is pretty phenomenal.

 Our other Bang, crash!! Is the work on our roof, scaffolding still here, banging, sawing and other sounds of re-construction continuing! 

I've set the light traps a couple of times, and they are also out tonight. Best from the 3rd September was a copper underwing. These are not the easiest things to ID without dissection, but I'm not keen to kill them unnecessarily. There is a lot of rubbish around about how to ID these. Even the usually reliable UK Moths re-iterates the labial palps colouring which is not a determining feature. The paper to look at is this "Entomologist’s Rec. J. Var. 134 (2022)", it's available online via Research Gate, (but posting the URL is causing Blogger issues...). (But the reference is here, at the bottom of the page - https://literateherringthisway.blogspot.com/search?q=copper+underwing I've demonstrated that the palps issue is no good via my own dissections, there's a not very good post in this blog previously.

Anyway, here's the latest one, including a palps image. It was a tad worn but my view would be that this is Copper Underwing Amphipyrea pyramidea, as always happy for other views to be expressed via "Comments".

 There were some interesting "intruders" from 3rd, including this large bark-louse, which was new for me.

From the 8th I captured two moths that were new for the garden and NFM, excellent. 

Lathronympha stigana, quite a small micro.

Not a lot of moths but quality.

The two Red Deer stags can also be seen regularly just over the fence in the Earthquake Field.

A wander in the woods produced a few of these which I'd looked for earlier in the year. Bird's Nest Orchid seems easier to find as seed heads.
