Conistra rubiginosa returns

 Very little in trap, but the first Conistra rubiginosa for the year in Denham - as usual undeterred by a cold night (Nov. 28-29). So keep those traps working from time to time, and ignore the temperature!




Absent Mottled Umbers

 I have had neither Mottled, nor Scarce ditto this year; and none in local woods either. Is this a common experience elsewhere?

Plutella xylostella?


I think this is Plutella xylostella, as there is just a hint of the dorsal pattern, and the overall "jizz" looks right, but would appreciate comments!

Thanks

Westcott, Bucks

Things keep ticking over in the garden here.  On the 21st there was just a single Red-green Carpet to the overnight actinic light, the closest I've come yet to having a blank night this winter, but otherwise there has always been a selection of the few species which are still around locally at this time of year (for example, seven moths of five species last night, all macros).  Recorded over the past week have been Zelleria hepariella, Emmelina monodactyla, December Moth, Red-green Carpet, Winter Moth, Feathered Thorn, Scarce Umber, Mottled Umber, Sprawler, Brick & Silver Y.

Zelleria hepariella, Westcott 23rd November

Sprawler, Westcott 24th November

Silver Y, Westcott 25th November

Zelleria hepariella is one of the handful of lepidoptera species which use ash as their sole larval food-plant.  It still seems to be doing reasonably well despite the fungal disease Hymenoscyphus fraxineus (Ash Die-back) which is causing the demise of many trees locally.  Although never common, it is a moth that can usually be relied upon to put in a single garden appearance here each year.  This example was actually the third for 2022 and I've had it to light at four other sites in the county too.

Brick (one here on the 25th) seems to be the longest-lived of the autumnal species and records of very faded examples in mid-December are nothing unusual nowadays.  However, it is getting a bit late now for Sprawler, of which there were two in the garden on the 24th.  In past years it has occasionally lingered on until the end of this month but I have never yet had a December record.  The December Moth count is now up to 24 for the year, even though we haven't got to December yet, and amongst them have been five females so far.

Just when I think . . . . .

 . . . . .that I'm getting the hang of some basic micros, this turns up. Came to light on Sept 3rd near Chesham- can't find anything that looks like it in the books. Someone please put me out of my misery?



Thanks, David

Earlier in the year

On the 4th August, this smart micro turned up in Stoke Goldington. Looks (to me at least) a candidate for Bryotropha basaltinella, but would need the chop to be sure?

Westcott, Bucks

Three or four days ago, with the weather having turned much colder and wetter, I wasn't surprised that catches dropped away considerably and just three moths came to the twin-30wt actinic light on each of Wednesday and Thursday nights (December Moth, Red-green Carpet & Mottled Umber on Wed 16th and Red-green Carpet, Winter Moth & Scarce Umber on Thurs 17th).  I was beginning to think that was it for the year, but last night there was an upturn thanks to it being calm, dry and overcast.  The temperature still fell away to 4 or 5 degrees here but those moths which fly at this time of year are used to the cold (Winter Moths in particular seem to have glycol in their veins!).  The light brought in Agonopterix heracliana (1), Epiphyas postvittana (1), Eudonia angustea (1), December Moth (2), Red-green Carpet (1), Winter Moth (2), Feathered Thorn (4), Scarce Umber (5), Mottled Umber (1) & Brick (1).

Scarce Umber, Westcott 18th November

Prior to the cold snap we had another period with southerly winds when a number of good migrants were seen in the country (including Diasemiopsis ramburialis and Nigel's Diplopseustis perieresalis in our area), but nothing significant turned up here.  A Dark Sword-grass on the 12th and Silver Ys on the 12th and 14th were all that visited Westcott, that's apart from further appearances by Plutella xylostella, Udea ferrugalis & Nomophila noctuella as well as several examples of Turnip Moth, White-point and Angle Shades which may or may not have been migrants.  Some of the Turnips were very fresh and quite nicely marked, like the male below. 

Turnip Moth, Westcott 14th November

Since the 13th the twin-30wt light has been run on the window-sill inside our conservatory, something I've been doing during the winter months for several years now and it has made no noticeable difference to the number of moths recorded.  I check the windows once or twice in the evening and again before dawn, potting up any arrivals, but it saves having to mess around with a trap which at this time of year few of the moths actually enter anyway.  I probably won't put a trap out in the garden again until the end of March.

Diplopseustis perieresalis

 A  Diplopseustis perieresalis was attracted to our house lights (Loosley Row) last night. I see, going back through the blog that Dave caught one in 2016.

Two 'plume' species

 Hi there,

These two turned up on Thursday night near Chesham - outside the Robinson on an adjacent white-painted door. From Page 92 in the Berkshire book, I make the first one Stenoptilia bipunctidactyla, but it looks nothing like the illustration of the same species in Sterling and Parsons.

And is the second one just a dark form of Emmelina monodactyla? The first insect was quite a bit bigger than the second.

If I'm right, then are both flying later in the year than usual - maybe due to the mild weather??

Thanks, David



Vagrant China-mark, Diasemiopsis ramburialis, Worminghall. A first for Bucks.

Very pleased to finally catch a decent autumn migrant this morning. Was even more pleased (and surprised) to find out it's a county first too.

Thanks very much to Dave and Martin for confirming. 


Vagrant China-mark,  Diasemiopsis ramburialis

Plumed Prominent

I trapped at Warburg last night with 3x 125w Robinson MV and an 8w actinic, from 17.15 to 20.45 when the moon pretty much killed it. There were 17 Plumed Prominents, all males. 19 species, including a late Metalampra italica and 2 migrants, Plutella xylostella and Nomophila noctuella.

Plumed Prominent

My annual pilgrimage to the Marlow area to check whether or not Plumed Prominent is flying yet wasn't actually needed this year as we'd already had the welcome report from Turville on 5th November (see the blog entry from a few days ago below).  Bonfire Night was traditionally the time to start looking for this nationally scarce species but it seems to have been appearing anything up to a week later than that locally over the last decade or more and in some years I've had to make several repeat trips.  However, last night I couldn't resist the urge to take another look myself and ran traps in two woods in adjacent kilometre squares to the north-west of Marlow.  Five came to light in Homefield Wood (Forestry Commission/BBOWT) and another pair in Pullingshill Wood (Woodland Trust), those totals suggesting to me that next week should bring even better numbers if anyone cares to go out looking for it.  The first appearances last night were at around 6.30pm and the last at 8.30pm while I was packing up.  As can be seen from the on-line Atlas, for reasons unknown the moth is confined in our region to that area of the Chilterns where our three counties meet.

Plumed Prominent, Homefield Wood 10th November

Other species seen in Homefield Wood last night comprised Ypsolopha ustella, Plutella xylostella, Scrobipalpa costella, Blastobasis lacticolella, Epiphyas postvittana, December Moth, Oak Hook-tip, Red-green Carpet, Spruce Carpet, November Moth agg., Feathered Thorn, Lesser Yellow Underwing, White-point, Satellite, Chestnut, Brick & Vine's Rustic, along with a Dark Bush-cricket and two very late Hornets.  The only additional species in Pullingshill Wood was Acleris sparsana.

Which Agriphila?


 

This has waited since 23rd August - well, I've been busy. I'm thinking probably tristella, but could it be straminella?

Many thanks, David

Scarce Umber

This rather poorly-marked Scarce Umber came to the actinic light at Westcott last night, accompanied only by Winter Moth (2), Sprawler (4) and a single example of the Diamond-back Moth Plutella xylostella.

Scarce Umber, Westcott 8th November

The 2022 garden year-list has already passed 700 species and when dissections are complete is certain to overtake last year's final total of 712, meaning that this will have been a record year here for species numbers if not for overall moth numbers (although they were much improved over 2021).  Scarce Umber is the last of those moths I can reasonably expect to add to the current year-list.  However, in November 2021 I was lucky enough to get two completely new species for the site after Scarce Umber had put in its appearance (Cypress Carpet & Red Sword-grass) so there's still the faint hope that something unexpected might turn up, especially as we still have several more nights of southerly winds before the cold weather sets in!

Crimson Speckled & Plumed Prominent in Bucks

On 5th November Luke Harman recorded a single Crimson Speckled and 3 Plumed Prominent. Both species new to the site at Turville in South Bucks. Thanks to Luke for supplying the information

A Berkshire Migrant

Three moths of three species last night. Eudonia angustea and Red-green Carpet were not unexpected but this one was a surprise.


Ben Dale on the Berkshire Moth Group Facebook page has kindly confirmed it as Diasemiopsis ramburialis

Another garden newcomer

Last night (5th November) it did at least remain overcast to keep the temperature into double figures, even though there was also plenty of rain.  30 moths of 13 species came to the trap including four micros, two of which provided all of the interest because they were new for the year-list:  Povolnya leucapennella and Bedellia somnulentella.  

Povolnya leucapennella, Westcott 5th November

Bedellia somnulentella, Westcott 5th November

Povolnya leucapennella, instantly recognisable with that "beak" of a scale tuft beneath its palps, seems to be a genuinely uncommon moth in Bucks despite the larval food-plant being oak.  There are only six previous records, all from the far south of the county and four of those are from the Rothamsted Insect Survey trap at Burnham Beeches.  Needless to say, this was a completely new moth for the garden.  Bedellia somnulentella has been recorded here previously both as the adult and at the larval stage (active mines on bindweed) but is another uncommon moth in the county although in this case it must be through under-recording. There are only 16 previous records and, again, half of those come from the RIS trap at Burnham Beeches.

Could this be a Delicate?

I had a single moth to my garden trap last night - the individual shown below. It is rather worn, and the picture is taken in fairly poor light. I wondered if it could be a Delicate?

The End is Nigh

It got quite chilly here last night and I wondered if that might tempt out the first Winter Moth of the season.  Sure enough, one did appear at the twin-30wt actinic trap, accompanied only by December Moth (3), Sprawler (1) & Red-line Quaker (1).

Tortrix for ID

This is my first season recording micros although in the past I did extensively record macros when living in Cambridgeshire and Cheshire.

I am working through a few outstanding records from earlier in the year and would appreciate comments on these three. On the 31st of July I caught this one and posted the picture on the Berkshire Moth Group Facebook page but no one suggested an ID. I then posted it on the UK Micro Moth page and Ben Sale suggested Rhopobota stagnana which appears to be a fairly rare moth in the County.


Then on the 3rd August I caught this one and didn't recognise it as the same thing - there were a lot of moths in the trap late July and early August although looking now it certainly looks like the same thing.

I posted the image on the Berkshire Moth Group page and Ben Dale kindly id'ed it for me as a second R. stagnana.

I've been sorting through my photos over the last few weeks and have found this one from the 1st August

which looks like a third record.


Worminghall, Bucks

Unfortunately no mega migrant here during the recent influx (although I did desert my post for a few days and headed to the coast to find some). Highlight was an Oak Rustic (the first for the garden) and a few nice migrants including 2 Delicates, up to 17 Rush Veneer in one night (30th October), a Vestal, a Diamond-back and a couple of Rusty-dot Pearls.  Also a late Clifden Nonpariel on 25th October and a few new for years including Sprawler and December moth and another potential new for garden in the form of an Acleris kochiella/logiana (awaiting dissection) which takes the 2022 garden year list to 492 (unverified).

December Moth

The first garden December Moth of 2022 turned up here last night.  Despite all the wind and rain it was accompanied by a reasonable selection of other species, including Udea ferrugalis, Nomophila noctuella, Red-green Carpet, November Moth agg., Feathered Thorn, Turnip, Large Yellow Underwing, Merveille du Jour, Blair's Shoulder-knot, Sprawler, Satellite, Beaded Chestnut & Barred Sallow.

December Moth, Westcott 2nd November

I saw my first December Moths of the season in Yardley Chase, close to the Northamptonshire border, back on 27th October and several more in Bernwood Forest two days later, so it should be starting to appear everywhere now.
