Review of 2019 and 2020 - Moths: Geometers (Geometridae) - part 8: Pugs III and Seraphims etc. (Eupithecia III to Trichopteryx)

GEOMETERS (GEOMETRIDAE) (continued)


Common Pug Eupithecia vulgata - Totals of 146 in my garden between 15th May and 4th July 2019 and 119 between 26th April and 29th June 2020.  146 is my highest total so far (average is 114).  Elsewhere 15 at the meadows and also recorded at Bintree Wood, Sculthorpe Moor, Hills and Holes, Weybourne, Keswick (Cumbria) and on Mull.  I'm always a bit paranoid about overlooking one of the scarce or rare pugs so tend to check more than I probably really need to, but this approach has got me a few interesting records in the past that I would have overlooked (including one or two of my Satyr Pugs for example).  Worn ones can be particularly confusing and it's not all that unusual for me to get mixed up between even familiar species like Grey Pug.  I've picked fresher examples to show below so these are among the more straightforward ones that I checked, although the third one had me quite puzzled, not that there were any clear candidates for an alternative ID.

Mottled Pug Eupithecia exiguata - A total of 11 here 19th May and 2nd June 2019 making it just about my worse year here (average about 16) followed by an on-par 16 between 8th May and 1st June 2020.  Elsewhere one at the meadows and 2 at Hills and Holes.

Yarrow Pug Eupithecia millefoliata - One in the garden on 23rd July 2019 was a new moth for the garden and only my second adult anywhere.

female Yarrow Pug, North Elmham, 23rd July 2019

Tawny Speckled Pug Eupithecia icterata - Totals of 7 caught in the garden between 25th July and 25th August 2019 and 14 between 8th and 19th August 2020, either side of the average of around 10-11 per year.  Elsewhere one next door and one at Swanton Great Wood on 27th August 2019.


Bordered Pug Eupithecia succenturiata - 4 in the garden between 5th July and 8th August 2019 and 5 between 24th July and 11th August 2020 (the last being my latest ever).  5 was my best annual total but this species is quite erratic with 3-4 in 2016, 2018 and 2019 and none at all in 2015 or 2017.  Elsewhere one at the meadows on 7th July 2019 and one next door on 8th August 2019.

Shaded Pug Eupithecia subumbrata - None.  This is quite scarce in Norfolk away from the Brecks and the coast but I caught one here in my garden in 2016 and 2 together in 2017.


Grey Pug Eupithecia subfuscata - Totals of 12 trapped here between 2nd June and 12th July 2019 and 10 between 21st May and 1st July, which are very average numbers.  Elsewhere 3 at the meadows, one at Hellesdon, one at Hills and Holes (on 21st May 2020, my earliest ever) and 5 on Mull.

Treble-bar Aplocera plagiata - An average year in 2019 with 10 trapped here between 2nd June and 30th August then an exceptional 37 between 18th May and 26th August 2020 (my previous best annual total was 15).  Elsewhere one at Row Heath (West Runton) on 31st August 2019 and one at the meadows on 8th September 2020. 

Treble-bar, North Elmham, 18th May 2020

female Treble-bar, North Elmham Cathedral Meadows, 8th September 2020

Lesser Treble-bar Aplocera efformata - None.  I carefully check each and every Treble-bar I find for Lesser Treble-bar but so far have found absolutely no evidence that they exist.


Streak Chesias legatella - Singles caught in the garden on 17th October 2019, 17th October 2020 and  8th November 2020.  These were my 3rd to 5th records here following singles in November 2014 and November 2015.

Broom-tip Chesias rufata - None.  I've only seen this species in the Brecks which is where the vast majority of recent Norfolk records have been, but there are a couple of recent records from elsewhere in the county and a good spread of older records, and there are some good patches of Broom locally so I'm optimistic that it might be lurking round here somewhere.


Grey Carpet Lithostege griseata - None.  Like Broom-tip, Grey Carpet is mainly found in the Brecks and that's the only place I've seen it.  However unlike Broom-tip, there have been quite a few records of Grey Carpets in mid Norfolk (e.g. Dave Norgate had one in Toftwood in 2018 and David Knight has had one just down the road from here in Worthing) so I reckon I've got more than half a chance of getting one locally sometime.


Seraphim Lobophora halterata - I think this was one of the 2-3 commonest moths that I'd not seen until 2019 but that year it finally gave itself up with one to MV light at the meadows on 25th May, swiftly followed by another to LEDs at a different part of the meadows on 31st May.  Further afield one at Hills and Holes on 21st May 2020.

Small Seraphim Lobophora halterata - Singles trapped in the garden on 11th July 2019 and 24th June 2020.  I've now caught 5 here, until the last one all in odd years.

Yellow-barred Brindle Acasis viretata - Just one caught in the garden in 2019, on 8th August.  Numbers of this species fluctuate greatly but this was exceptionally bad - 5 was my previous worst year and in 2016 I caught 38.  2020 was only a bit better with 7 between 5th and 21st August.  Elsewhere one at the meadows on 4th August 2019.

Yellow-barred Brindle, North Elmham Cathedral Meadows, 4th August 2019

Early Tooth-striped Trichopteryx carpinata - None in 2019 but I added this species to my garden list in 2020 catching one on 22nd April and then a different one on 24th April.  There was only one previous record in this 10km square but having caught one at my last house in Bawdeswell and also one at Bawdeswell Heath, I knew they weren't very far away.

Orange Underwing Archiearis parthenias - None.  I haven't found this species in North Elmham yet but I've had it not very far away in Bintree Wood (and at Sparham Pools).  I generally don't find many day-flying moths in my garden (although maybe there's a chance as there's a Birch in my front garden and another in the neighbour's garden behind mine) and I don't have much chance at the meadows either as the meadows are quite Birch-depleted.

Hawk-moth double act and a new Springtail

I found this Yellow-barred Brindle by the trap as I went to check it on the evening of Tuesday 15th, a new one for the year.

Yellow-barred Brindle, North Elmham, 15th May

There didn't seem to be many other moths in the trap and sure enough when I went through it in the morning there were only a dozen.  But these included my first two hawk-moths for the year, side by side on the same egg tray: Poplar Hawk-moth and Eyed Hawk-moth.  The others were Dark-barred Twin-spot Carpet, Common Pug, Brindled Pug, 2 Brimstone Moths, Waved Umber, Pale Tussock, White Ermine, Early Grey and Nut-tree Tussock (and there was a Case-bearing Clothes Moth Tinea pellionella indoors).

Next day Common Wave and 2 Spectacles were new for the year.  There were also Beech Midget Phyllonorycter maestingella, Common Pug, 2 Scalloped Hazels, Muslin Moth, Flame Shoulder, Hebrew Character and a Common Earwig.

The following night Garden Pebble Evergestis forficalis and Small Square-spot were added to the garden year list, and there were also Green Carpet, 3 Common Pugs, 2 Scalloped Hazels, Lesser Swallow Prominent, Coxcomb Prominent, Shuttle-shaped Dart, Flame Shoulder and Hebrew Character.

Small Square-spot, North Elmham, 17th May

There was one other thing in the trap of note, a springtail.  Unlike the springtail I saw at the meadows a few days earlier the third segment of the antennae was of an even width, indicating this was genus Tomocerus.  This one had spines on the dens that I could see clearly (well, clearly once I had gently prised the two prongs of the furcula apart), and they were simple, not tri-dentate, indicating (I think) that it was Tomocerus vulgaris, a new species for me.  Although it was alive and kicking (or rather jumping) when I got it out of the trap, by the time I went to photograph it an hour or two later it had already died, so my only shots are of a dead springtail I'm afraid.  It doesn't show very well in the photo but under the microscope you could clearly see how the irridescent scales formed discrete bands around each segment of the abdomen, which I believe is characteristic of this species.

Foulden Common

My first night back after my trip to Cornwall was a poor one for moths with just Yellow-barred Brindle, Early Thorn and 2 Hebrew Characters.  The first of those was a new species for the year.

Yellow-barred Brindle, North Elmham, 8th April

There was also this tiny juvenile Common Earwig and, in the house, another Varied Carpet Beetle.

Common Earwig, North Elmham, 8th April

Sunshine the next day produced Brimstone butterflies at a couple of places and in the evening I headed off to have a look round Foulden Common.  This is a site I've never visited before but have heard it mentioned a few times in the context of mothing.  The exposed parts of the west side of the common were too breezy to be any good but I caught Brown Birch Slender Parornix betulae and Double-striped Pug here, along with the green and brown lacewings Chrysoperla canea and Hemerobius humulinus.

Hemerobius humulinus, Foulden Common, 9th April

The eastern side was more sheltered and I netted another Double-striped Pug and an Early Purple Eriocrania semipurpurella.  The latter are quite hard to identify with certainty and although I had probably seen it before I hadn't managed to confirm any of the previous ones, so good to get one I was happy with at last.

Early Purple Eriocrania semipurpurella (female, gen det), Foulden Common, 9th April

Actually "gen det" simplifies it a bit too much - the ID was done through a combination of the hindwing scale width, the size and separaton of the sensoria (basically holes) on the bottom of the abdomen and a tiny little bit of its genitalia.

This leafhopper was a very common species, Empoasca vitis.

Empoasca vitis, Foulden Common, 9th April

As it got dark I decided conditions weren't good enough to bother setting up the MV light but did another quick circuit of the common with a headtorch.  This confirmed my suspicion that conditions were not good as all I added were Water Carpet and Early Thorn.  Oh, and a few click-beetles flying around which all looked the same and the one I retained for checking proved to be Dalopius marginatus.

Dalopius marginatus, Foulden Common, 9th April

Not many moths at home either, although 3 different micros made for a change.  These were Streaked Flat-body Depressaria chaerophylli (new for the year and a species I've only seen twice before) Common Flat-body Agonopterix heracliana and another new one for the year, Narrow-winged Grey Eudonia angustea.  Macros consisted of Shoulder Stripe, 2 Streamers and 3 Hebrew Characters.

Streaked Flat-body Depressaria chaerophylli (female, gen det), North Elmham, 9th April

Other insects in the trap were a Black Sexton Beetle and a new hoverfly species for me, Platycheirus albimanus.  Most examples of this genus (which I'd never encountered before) are characterised by the modifications on the front tarsi which you can see in the image below (the yellow feet sticking out behind the eyes).

Platycheirus albimanus, North Elmham, 9th April

The following night another Streaked Flat-body Depressaria chaerophylli was the highlight.  Muslin Moth was new for the year and there were also Streamer, Early Thorn, Oak Beauty and 2 Hebrew Characters. A German Wasp was also new for the year.
