Review of 2019 and 2020 - Moths: Noctuids (Noctuidae) part 8: Chestnuts and allies, Pale Pinion and Shoulder-knots

NOCTUIDS (NOCTUIDAE) (continued)


Beaded Chestnut Agrochola lychnidis - Totals of 37 caught here between 20th September and 5th November 2019 and 24 between 18th September and 19th October 2020, my worst years yet (although the 2020 total was reduced by me being away for a few nights in early October).  Plotting my annual totals here gives me a smooth downward curve from the 84 here in 2014.  Elsewhere 79 over 7 nights in Cornwall in early October 2020 and 2 at the meadows on 8th November 2020.

Brown-spot Pinion Agrochola litura - Singles in the garden on 3 consecutive nights 2nd to 4th October 2019.  I caught 30 of these in 2014 but in the 5 years since then I've only caught 19 in total; 2020 was my first year without catching any at all.

Brown-spot Pinion, North Elmham, 2nd October 2019

Flounced Chestnut Agrochola helvola - None.  I first saw this species in 2017 and that remains the only one I've caught here.


Red-line Quaker Agrochola lota - Totals of 10 in the garden between 2nd October and 2nd November 2019 and 24 between 22nd September (my earliest ever) and 7th November 2020.  I've averaged about 11 a year here and 2020's total was my highest ever, and included my best count of 4 on 20th October.

Red-line Quaker, North Elmham, 2nd October 2019

Yellow-line Quaker Agrochola macilenta - Totals of 22 in the garden between 14th October and 27th November 2019, the last being my latest ever, and 17 between 17th October and 15th November 2020.  These totals were a fair bit below the average annual total of over 35.  Singles seen at the meadows on 5 dates from 4th October 2019.

Yellow-line Quaker, North Elmham Cathedral Meadows, 4th October 2019

Brick Agrochola circellaris - None here in 2019 but 5 between 2nd and 13th November 2020.  I've had poor years before (e.g. just one in 2016) but 2019 was my first complete blank.  I've caught up to 12 here in a year, averaging at 5.  Elsewhere 9 at the meadows on 4 dates (mostly on Ivy) including 5 on 4th October 2019.

Lunar Underwing Omphaloscelis lunosa - Totals of 360 caught in my garden between 10th September and 14th October 2019 and 348 between 8th September and 20th October 2020, both over my average annual tally of 282.  Elsewhere 316 in Cornwall in the first week of October (including 92 at our Tresidder cottage on 8th October).  Incredibly, I haven't managed to find this species at the meadows yet.

Lunar Underwing, Tresidder (Cornwall), 7th October 2020

Chestnut Conistra vaccinii - My best years for this species at home with 58 up to 27th March  2019 and then 17 from 1st October to the year end, 27 up to 10th April 2020 and then 66 from 29th September to the year end (including a record 8 on 16th October).  The totals of 75 and 93 compare with an average annual total of less than 60.  At the meadows recorded on 12 nights with a total of 24.  The record at home on 29th September 2020 and 4 at the meadows the same night were my earliest autumn records ever.  So far 2021 is shaping up to be another excellent year for this species.

Dark Chestnut Conistra ligula - 5 caught in the garden in the first winter period of 2019, up to 23rd February, then 4 in the autumn between 21st October and 24th November followed by one on 13th February 2020.  5 between 2nd October (my earliest ever) and 21st December 2020.  I average just under 7 a year here.  Elsewhere one at the meadows on 4th October 2019 and one in Cornwall in October 2020.  I find some Conistra quite difficult to be certain about and so dissect a few of the trickier individuals to confirm - the results suggest I'm being over-cautious as my suspected ID nearly always proves right, but I do occasionally get it wrong and sometimes think these are over-simplified, especially with worn examples.

Dotted Chestnut Conistra rubiginea - None at home in either year.  This species has very recently colonised Norfolk and is still spreading - I caught my first here in 2016 and a second in 2018.  Elsewhere one at Cranwich Heath on 14th March 2020.

Dotted Chestnut, Cranwich Heath, 14th March 2020

Tawny Pinion Lithophane semibrunnea - None.  This is a scarce species and I've never seen one, but it's pretty widespread so I remain optimistic that one will land in my trap sometime.


Pale Pinion Lithophane socia - Singles in my garden on 26th March 2019 (my earliest ever record) and 1st April 2020.  The 2019 individual had one wing very much shorter than the other.  This species isn't quite annual here though I average one a year.

Grey Shoulder-knot Lithophane ornitopus - singles caught in my garden on 17th October and 4th November 2019 and 18th October 2020.  1-2 a year is normal though numbers have varied from 0 to 4.

Blair's Shoulder-knot Lithophane leautieri - One trapped in the garden on 28th October 2019.  This recent colonist seemed to be going from strength to strength at the time I moved here and I caught 22 in my first autumn (2014).  Since then it slumped - I caught 4 in each of the next 2 years, 3 in 2017 and none in 2018 or 2020.  A temporary dip, as in the usual peak-and-trough cycle of insect populations, or a long-term trend signalling the end of a temporary colonisation?  Time will tell, but I suspect the former.

Eyed Hawk, a new froghopper and other bits and pieces

There were no stand-out highlights in the moth trap on 3rd September, though an Eyed Hawk-moth is always nice, especially after things have slowed down in the autumn.  The others were Light Brown Apple-moth Epiphyas postvittana, Garden Rose Tortrix Acleris variegana, 3 Common Marbles Celypha lacunana, 4 Common Grass-veneers Agriphila tristella, Elbow-stripe Grass-veneer Agriphila geniculea, Common Plume Emmelina monodactyla, 2 Brimstone Moths, 2 Light Emeralds, 12 Large Yellow Underwings, Lesser Yellow Underwing, 3 Setaceous Hebrew Characters, Square-spot Rustic, Nutmeg, 3 Common Wainscots, 5 Flounced Rustics, Rosy Rustic and Straw Dot.

At home that night Pine Carpet was new for the year.  Other highlights were Beech Pigmy Stigmella hemargyrella and Thatch Neb Bryotropha basaltinella. The former was my third this year of a species I hadn't previously recorded here and the latter was my fourth this year of a species that until this year hadn't been recorded anywhere else in Norfolk.

The following night the leafhopper Kybos betulicola appeared in my study

In the moth trap there were two new moths for the garden year-list, Brown-spot Pinion and Lunar Underwing.

Moth numbers continued to dwindle with the following on 6th: Garden Rose Tortrix Acleris variegana, Barred Marble Celypha striana, Common Marble Celypha lacunana, 2 Elbow-stripe Grass-veneers Agriphila geniculea, Ringed China-mark Parapoynx stratiotata, Single-dotted Wave, Brimstone Moth, 5 Large Yellow Underwings, 5 Lesser Yellow Underwings and Setaceous Hebrew Character.  There was one mayfly (Pond Olive Cloeon dipterum), one beetle (Bradycellus verbasci) and these caddisflies: Hydropsyche pellucidula, Mottled Sedge Glyphotaelius pellucidus, Limnephilus flavicornis, 6 Limnephilus lunatus and Limnephilus sparsus.

Next day a walk round the meadows produced a few insects including Migrant Hawker, Common Darter, Small Copper and Comma.

A White-shouldered Smudge Ypsolopha parenthesella was the only adult moth found but vacated leaf-mines of Scrubland Pigmy Stigmella plagicolella and 2 Apple Leaf-miners Lyonetia clerkella were also seen.

Other insects included 2 7-spot Ladybirds, the hoverfly Myathropa florea, a Turnip Sawfly and lots of wasps feeding on ivy.  They included lots of Common Wasps, at least one German Wasp and 2 Hornets, but among them I had brief views of a Colletes bee which was very probably an Ivy Bee.  Ivy Bee was new to science as recently as 1993 and arrived in the UK in 2001, reaching Norfolk by 2014.  It is now common in many places but as hard as I tried to find one at the meadows this autumn this brief sighting was the nearest I got.  Sadly it wasn't quite good enough to be 100% sure - I believe there are one or two other Colletes species that can visit ivy at this time of year and my views were not sufficient to rule out one of them.

Turnip Sawfly, North Elmham Cathedral Meadows, 7th September

Shaking some Field Maple keys produced the barkfly Ectopsocus briggsi, a harvestman and 2 spiders.  The latter were I think immature, or at least I could not see enough detail in their epigyne to be able to match them to any species, but I think they were an Araniella sp. and a Philodromus sp.  My references on harvestmen are sparse but from searching the internet I'm pretty sure this one was Paroligolophus agrestis, a species I hadn't previously identified.

2 Sallows were new for the year the following night.
