Review of 2019 and 2020 - Moths: Erebids (Erebidae) part 1: Herald, Straw Dot, Snouts and Tussocks and allies

EREBIDS (EREBIDAE)


Herald Scoliopteryx libatrix - Singles in the garden on 23rd and 24th April and 2nd May 2019 and on 5th April 2020.  I've had between 1-4 every year I've trapped here.  I've not caught this species anywhere else since living here.

Straw Dot Rivula sericealis - At least 106 caught in the garden between 30th May and 25th September 2019 but no counts on 9 dates so the true total may have been higher (but possibly not a lot as a lot of counts of one around this period).  Almost certainly my worst year here, 2020 being the next worst year with 166 between 26th May and 30th September.  Over the previous 4 years I averaged nearly 460 a year.  Elsewhere caught next door on 3 nights, 20 seen at the meadows on 13 dates and 3-4 at Bintree Wood, Whitwell Street and Swanton Great Wood and singles at Hills and Holes and in Cornwall.

Snout Hypena proboscidalis - Totals of 105 caught in the garden between 23rd June and 20th October 2019 and 91 between 3rd June and 27th September 2020.  I catch more than double those totals in an average year - these were my worst totals so far.  Elsewhere a total of 29 over 17 dates at the meadows, 6 in Hellesdon, 9 in Cornwall and 1-2 at Bintree Wood, Whitwell Street, Swanton Great Wood, Weybourne and Row Heath (West Runton).

Buttoned Snout Hypena rostralis - One in the garden moth trap on 18th May 2020.  I've had 2 here before, in 2015 and 2017 (and 4 at my old house in Bawdeswell between 2010 and 2014).

Buttoned Snout, North Elmham, 18th May 2020

White Satin Leucoma salicis - None at home in either year or in any year since 2016, though 2 here in each of 2015 and 2016 and one next door in 2017.  One at the meadows on 18th July 2020 was my only record in 2019-20, my second here.

Black Arches Lymantria monacha - 4 caught in the garden between 22nd and 27th July 2019 and 6 between 18th and 26th July 2020.  I've never gone lower than 4 and the previous 2 years' totals weren't much higher but before that 22 in 2016.  Elsewhere one next door, 2 at the meadows, 3 at Bintree Wood, 5 at Swanton Great Wood and 2 at Row Heath (West Runton) on 31st August.

Gypsy Moth Lymantria dispar - I've never caught this species myself but I did get to see one that someone else caught in 2019.  I don't normally twitch moths that other people catch but I took a call from Chris Mills who said that a friend who was staying in his house (while he was overseas)and  had caught what appeared to be this species.  His friend wanted someone else to go along and see it in order to confirm the ID as as I was at Winterton I was happy to pop in on my way home and take a look.  After becoming extinct in the 19th century this species is re-establishing itself in a few areas in southern England.  This was the 5th Norfolk record since 2016 and there were another 5 records in 2020 so it seems like it may be in the process of colonising Norfolk.  In any case we can expect more in coming years...

Brown-tail Euproctis chrysorrhoea - 3 caught in the garden between 11th and 26th July 2019 and 9 between 13th and 29th July 2020.  3-4 a year here is normal but I'd never gone above 6 before.  Elsewhere one at Weybourne on 5th July 2019 and 30 at Brancaster on 2nd July 2020.

Brown-tail, Brancaster, 2nd July 2020

Yellow-tail Euproctis similis - At least 17 between 11th July and 3rd August 2019 and 40 between 18th June and 12th August 2020.  Although not counted on 3 nights in 2019, so the actual total may have been a little higher than 17, this was certainly my worst year for Yellow-tails here - I averaged 68 a year between 2015 and 2018.  Elsewhere a couple next door, 3 at the meadows (plus a caterpillar on 27th May 2020), one at Bintree Wood and 2 caterpillars at Titchwell on 1st June 2019.

Pale Tussock Calliteara pudibunda - Totals of 12 caught in the garden between 22nd April and 30th June 2019 and 7 between 9th and 22nd May 2020.  15 a year is average and these were my worst showings since moving here.  Elsewhere 4 at the meadows and 8 at Hills and Holes.

Vapourer Orgyia antiqua - Singles in the garden moth trap on 6th Augsut and 26th September 2020.  I'd only ever caught 2 here before (2015 and 2017) though I'd also found a caterpillar in 2014.  Elsewhere oone to light at the meadows on 30th July 2019 and then 3 seen in flight in daytime on 15th-17th October; another to light on 18th July 2020.  Also one day-flying at Cromer on 22nd October 2019.

A walk at Massingham Heath on 2nd October didn't produce much wildlife interest - a Common Nettle-tap Anthophila fabriciana was the only moth recorded.  A poor catch at home that night consisted of Narrow-winged Grey Eudonia angustea, Setaceous Hebrew Character, Black Rustic, Red-line Quaker, Lunar Underwing, Sallow and Rosy Rustic.

The following night Large Wainscot was new for the year.  Apart from that it was no better than the night before: Light Brown Apple Moth Epiphyas postvittana, Feathered Thorn, Setaceous Hebrew Character, Green-brindled Crescent and 2 Lunar Underwings.

The next few nights didn't get much better:

• 4th: Setaceous Hebrew Character, Lunar Underwing, Pink-barred Sallow, 2 Large Wainscots and the caddisfly Limnephilus lunatus. 

• 5th: just single Lunar Underwing and Pink-barred Sallow.

• 6th: Garden Midget Phyllonorycter messaniella, Rhomboid Tortrix Acleris rhombana, Narrow-winged Grey Eudonia angustea, Lunar Underwing and Limnephilus lunatus.

• 7th: Light Brown Apple Moth Epiphyas postvittana, 3 Narrow-winged Greys Eudonia angustea, Common Marbled Carpet, Feathered Thorn, Lunar Underwing, Snout and the beetles Nicrophorus investigator and 2 Leistus spinibarbis.

At Cley on 7th this caterpillar was on the boardwalk to the central hides.  I wasn't sure what it was, even if it is a moth or sawfly.  Turns out it wasn't either - thanks to James again for letting me know it's a soldier beetle larva -  I'd never have guessed that!

There was a slight upturn on the night of Sunday 8th with a Spruce Carpet and my latest ever (first in October) Treble Brown Spot.  Not much else though: 3 Light Brown Apple Moths Epiphyas postvittana, Garden Rose Tortrix Acleris variegana, 2 Narrow-winged Greys Eudonia angustea, 2 Mallows, Common Marbled Carpet, 3 Lunar Underwings, Pink-barred Sallow and Snout.

A Harbour Porpoise was about the only non-avian interest at Burnham Overy on 9th October.  That night at home I caught 3 Light Brown Apple Moths Epiphyas postvittana, 3 Garden Rose Tortrixes Acleris variegana, 2 Narrow-winged Greys Eudonia angustea, 2 Mallows, Common Marbled Carpet, Shuttle-shaped Dart, 2 Lunar Underwings, Pink-barred Sallow, Straw Dot, Chrysoperla carnea agg. (lacewing) and 3 Limnephilus lunatus (caddis).

The conditions around lunchtime on Tuesday 10th October must have been just right for ladybirds to be looking for somewhere to hibernate as between about 1 pm and 2 pm at least 36 Harlequin Ladybirds entered my study through the window which was only open a crack.  There were loads more outside that didn't find their way in too.  Among them all was a single 2-spot Ladybird, the first I've recorded here this year (though I'm pretty sure one that came in to hibernate towards the end of last year was still lurking in a corner into January at least).

That night there were 2 new moths for the year - one a lovely species I've only caught here once before and the other a very common and rather less attractive species - Vapourer and November Moth.

Other moths that night were 2 Light Brown Apple Moths Epiphyas postvittana, 6 Narrow-winged Greys Eudonia angustea, Mallow, Common Marbled Carpet, Feathered Thorn, Shuttle-shaped Dart, Large Yellow Underwing, 2 Setaceous Hebrew Characters, 2 Green-brindled Crescents, Lunar Underwing, Straw Dot and Snout.  Other insects included Chrysoperla carnea (lacewing), Limnephilus flavicornis, Limnephilus lunatus, 2 Limnephilus vittatus (caddisflies) and Lamprotettix nitidulus (leafhopper).

The following night there were 5 Narrow-winged Greys Eudonia angustea, Mallow, November Moth, Feathered Thorn, Beaded Chestnut, 2 Lunar Underwings and Barred Sallow, the last of which was new for the year.  No caddisflies, lacewings, bugs or beetles.

Barred Sallow, North Elmham, 11th October

It was just as quiet the next evening but still one new for the year - Yellow-line Quaker.  The others were 6 Narrow-winged Greys Eudonia angustea, Feathered Thorn, 2 Green-brindled Crescents, Lunar Underwing, Limnephilus lunatus, 2 Halesus radiatus (caddisflies) and Harpalus rufipes (beetle).

A Firethorn Leaf-miner Phyllonorycter leucographella was new for the year on 13th October.

This was one of a surprisingly good haul of micro moths which included several species I hadn't seen since the summer. Yellow-spot Tortrix Pseudargyrotoza conwagana is one I'd not seen anywhere near this late before and as it was fresh it must have been an unusual second-generation.  I had seen late Long-horned Flat-body Carcina quercana before but it's another one that the textbooks say should stop flying in August. Gold Triangle Hypsopygia costalis is another one that must be starting to have a second generation - this was my first in October while the Double-striped Tabby Hypsopygia glaucinalis is a bit more established at this time of year.  The other micros were more expected: 4 Garden Midgets Phyllonorycter messaniella, 2 Garden Rose Tortrixes Acleris variegana, 3 Narrow-winged Greys Eudonia angustea and Common Plume Emmelina monodactyla.

Bizarrely given the nunber of micros, macros were few and far between and every one of them was a noctuid (at least in old taxonomy).  At least with just singles of each it felt like there was some variety among them: Shuttle-shaped Dart, Black Rustic, Brown-spot Pinion, Beaded Chestnut, Barred Sallow, Large Wainscot, Burnished Brass, Straw Dot and Snout.

Beaded Chestnut, North Elmham, 13th October

There was some interest among the other insects too.  Two lacewings were both Chrysoperla but unusually only one was carnea, the other being Chrysoperla lucasina - just my third.  There weren't many caddisflies but they included my first ever Brown Sedges Anabolia nervosa, a male and a female, along with more usual Mottled Sedge Glyphotaelius pellucidus and Limnephilus vittatus.

Bugs and beetles consisted of Pinalitus cervinus, 2 Kybos sp. (probably betulicola), Edwardsiana sp., Aphodius rufipes and Orange Ladybird.

Silver Hook and other Surlingham goodies

Church Marsh, Surlingham was the destination for Norfolk Moth Survey's last night-time moth event in 2016 and I was keen to go along to this one, a site I've never visited before.  It was a windier night than we would have liked and it was a little difficult finding a site sufficiently sheltered.  We did the best we could and it turned out to be a thoroughly worthwhile night.

The star of the night was undoubtedly a Silver Hook - a scarce wetland species with its Norfolk stronghold in the Broads.  Perhaps surprisingly though, it has only rarely been recorded in the Yare Valley, and not since 1985, so this was a very pleasing result.

I was also pleased to see another Broads special, especially after missing one that was recorded by others at the last event at Claxton Manor - my first Reed Smudge Orthotelia sparganella.

A third lifer for me was the tiny Sallow Pigmy Stigmella salicis.  It is sometimes said that these Stigmella are too hard to identify with certainty to record as adults, and that there is no need to anyway as their mines are so easy to find.  Well for no logical reason I like to see adults before counting them, and I like a challenge, so I set about trying to resolve this one using the excellent Kleine Vlinders key.  Where a couplet was in the slightest bit equivocal I followed both options until I reached a dead-end on one, so I'm fairly certain I arrived at the correct ID - and I'm pretty sure there was a lot of its foodplant present too.

Other highlights included 2 Meadow-sweet Buttons Acleris shepherdana, Double-striped Knot-horn Cryptoblabes bistriga, 2 Oblique Carpets, Chevron, Vapourer, 4 Garden Tigers, Old Lady, Small Wainscot, 2 Crescents, Twin-spotted Wainscot, 6 Webb's Wainscots, Gold Spot and Pinion-streaked Snout.

Although Common Marble Celypha lacunana was suggested as the ID for this moth I don't recall seeing one quite like this so took it home to confirm.  Whoever called it that (Ben I think) was spot on.  There was a normal one too.

I was also slightly doubtful about this rather dark Flounced Rustic, although by the time I came to dissect it I had already convinced myself that was what it had to be - and I've seen a couple of similar ones since so perhaps it wasn't so odd after all.

The remainder that I saw were Horse Chestnut Leaf-miner Cameraria ohridella, Common Nettle-tap Anthophila fabriciana, Golden Argent Argyresthia goedartella, Diamond-back Moth Plutella xylostella, 2 Small Clover Case-bearers Coleophora alcyonipennella, Cyclamen Tortrix Clepsis spectrana, Barred Marble Celypha striana, Grey Poplar Bell Epinotia nisella, Marbled Piercer Cydia splendana, Common Grass-veneer Agriphila tristella, Elbow-stripe Grass-veneer Agriphila geniculea, 5 Water Veneers Acentria ephemerella, Marsh Grey Eudonia pallida, 2 Brown China-marks Elophila nymphaeata, Beautiful China-mark Nymphula nitidulata, 5 Small China-marks Cataclysta lemnata, 3 Rusty-dot Pearls Udea ferrugalis, Mother of Pearl Pleuroptya ruralis, Figure of Eighty, Small Dusty Wave, Common Carpet, Yellow Shell, Purple Bar, Green Carpet, Triple-spotted Pug, Currant Pug, Double-striped Pug, Dingy Shell, Clouded Border, Tawny-barred Angle, 2 Brimstone Moths, 2 Dusky Thorns, Common Wave, Light Emerald, Poplar Hawkmoth, Swallow Prominent, Dingy Footman, 2 Flame Shoulders, Large Yellow Underwing, Broad-bordered Yellow Underwing, Lesser Broad-bordered Yellow Underwing, Setaceous Hebrew Character, Six-striped Rustic, Square-spot Rustic, White-point, Southern Wainscot, Copper Underwing, Dark Arches, Lesser Common Rustic, Rosy Rustic, 2 Burnished Brasses, Silver Y, Spectacle, Straw Dot and Snout.


A Scorpion Fly proved to be Parnorpa germanica and although I can't remember what we thought at the time I think this beetle must be Great Silver Water Beetle (though open to contrary suggestions).
