Review of 2019 and 2020 - Moths: Erebids (Erebidae) part 3: Fan-foots, Small Snouts, Beautiful Hook-tip and Red Underwings

EREBIDS (EREBIDAE) (continued)


Dotted Fan-foot Macrochilo cribrumalis - Trapped in the garden on 25th June 2020 and 2nd July, the first I'd caught here since 3 in 2015-16.  Elsewhere one at Bintree Wood on 13th June 2020 and 3 at the meadows on 18th/23rd June 2020.

Dotted Fan-foot, Bintree Wood, 13th June 2020


Dotted Fan-foot, North Elmham, 25th June 2020



Fan-foot Herminia tarsipennalis - A total of 41 here between 24th June and 26th July 2019 was my worst year here but 2020 made it look good by returning just 16 between 19th June and 23rd July.  An average year here is 60.  Elsewhere 2 at the meadows and one at Hellesdon.

Fan-foot, North Elmham Cathedral Meadows, 7th July 2019



Small Fan-foot Herminia grisealis - I'd caught 54 here in my first 4 years 2015-18 with annual totals ranging from 8 to 24, so it was a bit of a shocker to have a completely blank year in 2019 followed by just a single one (on 26th June) in 2020.


Pinion-streaked Snout Schrankia costaestrigalis - Singles trapped here on 4 nights between 30th August and 24th September 2019 and on 20th August 2020.  I've had 3-6 here in each of the last 4 years but had a blank year in 2015.  Elsewhere one at Row Heath (West Runton) on 31st August 2019 and 4 in Cornwall on 6th/7th October 2020.


Blackneck Lygephila pastinum - None.  I was due a blank year or two after catching one, but only ever one, in each year between 2015 and 2018.


Waved Black Parascotia fuliginaria - None.  I've never seen this species and it's never been recorded round here, but it seems to be increasing in south Norfolk so it's perhaps just a matter of time before it turns up round here.  Hope so anyway.


Beautiful Hook-tip Laspeyria flexula - Totals of 17 here between 23rd June and 24th July 2019 followed by 3 autumn records between 9th and 25th September, then 22 between 12th June and 30th July 2020.  Although the 3 in September 2019 represented my best ever autumn showing the overall totals of 20 and 22 were my worst in the 6 years I've been here - I had been averaging 50 a year.  Elsewhere 6 at the meadows, one at Bintree Wood and 2 at Weybourne.

Beautiful Hook-tip, North Elmham Cathedral Meadows, 30th June 2019


Beautiful Hook-tip, North Elmham Cathedral Meadows, 23rd June 2020



Beautiful Marbled Eublemma purpurina - None.  I've never seen this species and until very recently it didn't seem particularly likely that I would see one in Norfolk.  After the first in Norfolk in 2016 there were 5 in 2018, 5 in 2019 and then 30 in 2020.  Given the spread of records and some repeated records of fresh individuals at inland locations it is impossible to conclude that these are all migrants - the species is clearly breeding in the county now.  Currently all the records are north or east of a line curving round from Dersingham across to Stibbard and down to Tasburgh.  I'm only just on the wrong side of that line so if things carry on going the way they've started then it won't be long before I catch one too.  Bring it on!!!


Clifden Nonpareil Catocala fraxini - None.  I've never seen one but rather like the previous species it's only the last couple of years that it has felt like I have anything more than an outside chance of finding one.  Compared to the last species there were a few more old historic records of migrants but the very recent colonisation follows a pattern that's uncannily similar except that there are a few records in the south-west quarter of the county too.  I'm very much looking forward to my first...


Red Underwing Catocala nupta - None in 2019 but 4 between 11th and 26th August 2020.  I have only ever caught 3 in my moth trap here, one in 2014 and 2 together in 2016, but in 2020 I started using sugar.

Red underwing, North Elmham, 11th August 2020


Red underwing, North Elmham, 26th August 2020



Dark Crimson Underwing Catocala sponsa - None.  Another former rare migrant that's very recently colonised the county.  Hopefully they will become a permanent fixture here and it won't be long before one finds its way to my sugar mix...


Burnet Companion Euclidia glyphica - None.  In Norfolk this species is largely restrited to the Brecks but there are a few records elsewhere.  As a day-flying species I'm not expecting to catch one in the garden but there is perhaps a small chance of me finding it at the meadows one day.


Mother Shipton Euclidia mi - None.  Another day-flying species that I don't particularly expect to catch at home but unlike the previous species there are a lot of records across Norfolk and away from the Brecks (although the Brecks is its stronghold).  It's not yet been recorded in this 10km square but I've had it this side of Beetley and I imagine it's quite likely to occur even more locally.

Review of 2019 and 2020 - Moths: Erebids (Erebidae) part 2: Ermines, Tigers and Footmen

EREBIDS (EREBIDAE) (continued)


Buff Ermine Spilosoma lutea - Totals of 105 caught in the garden between 1st June and 2nd August 2019 and 72 between 20th May and 28th July 2020, by far my worst years here.  I caught 247 here in my previous worst year.  Elsewhere caught next door (7th August), at the meadows (3 dates), Bintree Wood (2), Hellesdon (5), Hllls and Holes, Weybourne (2) and on Mull (2).  Also a caterpillar at the meadows on 4th October 2019.

Buff Ermine, Bintree Wood, 13th June 2020



White Ermine Spilosoma lubricipeda - Totals of 28 caught in the garden between 18th May and 23rd June 2019 and 34 between 16th May and 16th June 2020.  As with the previous species these were my worst totals since moving here - my average annual tally is 60.  Elsewhere 5 at the meadows, 3 at Bintree Wood, 6 at Hills and Holes and a total of 37 on Mull.  One of the latter was found at an un-manned honesty shop at Lochbuie, during the day and deep inside a basket of cakes - clearly a moth after my own heart.

White Ermine, North Elmham, 20th May 2020



Water Ermine Spilosoma urticae - None.  In Norfolk this species is pretty much restricted to the Broads which is where the only one I've ever seen was.  However the other moth-trapper in my road caught one in 1996 and there have been a handful of other more recent records this side of the county, so there must be at least a small chance of me getting one locally.


Muslin Moth Diaphora mendica - Totals of 43 caught in the garden between 1st April and 28th May 2019 and 94 between 12th April and 24th May 2020.  The 2019 total was pretty typical but the 2020 total was a record high (and included a record count of 9 on 3rd May).  It's normally only the males that come to light and I've only caught males here.  I never managed to catch a single one at my last house in Bawdeswell - in fact I've only ever had one male to light anywhere else (I've also seen a couple of females at other sites, both during the day).

Clouded Buff Diacrisia sannio - 4 seen, all on Mull in June 2019: one during the day along the path from Carsaig to Rubha Dubh, singles in torchlight at 2 sites and one to an outside light at our accommodation in Carsaig.  In Norfolk this species is largely restricted to the Brecks, the only area I've seen it before.


Clouded Buff, Allt Molach (Mull), 13th June 2019


Clouded Buff, Carsaig (Mull), 13th June 2019



Ruby Tiger Phragmatobia fuliginosa - At least 34 caught in the garden between 18th May and 10th August 2019, but not counted on 2 nights so perhaps a few more.  That's pretty much average here but the 8 bewteen 14th July and 4th August 2020 was by far my worst year here.  Also a caterpillar here on 26th February 2020.  Elsewhere one next door, 28 at the meadows (on 8 nights) , 4 at Bintree Wood, one at Whitwell Street and one in Hellesdon.

Garden Tiger Arctia caja - One in the garden trap on 20th July 2019.  I've only had this species here twice before (both 2017 when I also caught one next door).  None here in 2020 but one at Brancaster on 2nd July.




Garden Tiger, North Elmham, 20th July 2019


Garden Tiger, Brancaster, 2nd July 2020



Cinnabar Tyria jacobaea - Totals of 14 caught in the garden moth trap between 22nd May and 2nd July 2019 and 17 between 19th May and 26th June 2020, my worst totals since moving here (average annual total is 42).  Elsewhere 5 at the meadows, 3 at Bintree Wood and 9 at various sites on Mull,  comprising a mixture of day time observations and individuals coming to light.  Also at least 30 caterpillars on Ragwort at the meadows on 5th July 2019 and smaller numbers the following year.  At Titchwell on 21st July 12 adults seen during the day and also some caterpillars.

Cinnabar caterpillar, North Elmham Cathedral Meadows, 19th July 2019



Rosy Footman Miltochrista miniata - At least 172 caught here between 4th July and 7th August 2019 but probably a few more as they weren't counted on 3 nights.  Also an autumn generation example on 30th September.  This is about average here, but 2020 was my worst year so far with just 80 between 25th June and 15th August 2020.  Elsewhere one next door, 8 at the meadows (4 nights), 2 at Bintree Wood and one at Weybourne.

Rosy Footman, North Elmham Cathedral Meadows, 7th July 2019


Rosy Footman, North Elmham, 25th June 2020



Muslin Footman Nudaria mundana - None.  I've never seen this scarce species but there are scattered records around the county including a couple not all that far away from here, so I'm hopeful that I'll get one sometime.


Round-winged Muslin Thumatha senex - At least 22 here between 5th July and 4th August 2019, with 2 nights not counted.  That's my best year so far, with an average of 10 a year previously.  In contrast 2020 was my joint worst year with 6 between 8th and 31st July.  Elsewhere one at the meadows and one at Hellesdon in 2019 and 15 at the meadows on 18th July 2020.

Round-winged Muslin, North Elmham Cathedral Meadows, 7th July 2019


Round-winged Muslin, North Elmham Cathedral Meadows, 18th July 2020



Four-dotted Footman Cybosia mesemella - One at Bintree Wood on 13th June 2020 was my only record in 2019/20.  I caught 8 of these in my garden between 2015 and 2017 but none since.

Four-dotted Footman, Bintree Wood, 13th June 2020



Four-spotted Footman Lithosia quadra - None.  I've only ever caught this migrant species once in east Norfolk and in Cornwall.  David Knight has caught one just down the road at Worthing so no reason why one shouldn't appear in my trap one day.


Red-necked Footman Atolmis rubricollis - None.  I caught 21 of these between 2102 and 2016, some in their Breckland stronghold but also at quite a few different sites away from the Brecks (including once here at home, in 2015).  They were often fresh individuals and not coinciding with arrivals of migrants, so it was concluded that they had spread and colonised more of the county than just the Brecks.  Sadly it all seems to have gone a bit quiet since then.  Hopefully it's just a cyclical dip - it is still being recorded away from the Brecks in smaller numbers which suggests it is hanging on, and that being so perhaps we can expect another peak quite sooon.  I certainly hope so - they're smart moths!


Buff Footman Eilema depressa - 6 in the garden between 22nd and 25th July 2019 and just 2 in 2020, on 16th July and 12th August.  These were my worst totals since moving here - I had been averaging over 15 a year.  Elsewhere 5 at Bintree Wood on 24th July 2020 and my first at the meadows on 7th August 2020.

Buff Footman, North Elmham Cathedral Meadows, 7th Augsut 2020



Dingy Footman Eilema griseola - Recorded in the garden on 33 nights between 7th July and 20th August.  I didn't count them on 9 nights starting during their peak flight period (37 on 24th July) so impossible to estimate how many in total (139 on the nights I did count).  However, having averaged well over 300 a year over the previous 4 years, I'm pretty sure this was a poor year.  2020 certainly was - 179 between 28th June and 19th August was my lowest count other than the incomplete 2019 total.  Elsewhere 28 at the meadows, 55 at Bintree Wood on 24th July, 2 in Hellesdon and one at Row Heath (West Runton).


Common Footman Eilema lurideola - Recorded at home from 5th June 2019 with 722 by 24th July (when counts peaked at 73).  Recorded without counts on another 11 nights until 5th August.  Over the previous 4 years I had averaged 785 a year.  2020 was my best year so far with 989 between 10th June and 8th August.  Caterpillars in the moth trap on 1st March, 30th May and 10th and 26th December 2019 - presumably the eggs had been laid in the trap rather than they had crawled into it).  Elsewhere 22 at the meadows (10 nights), 12 at Bintree Wood, 10 at Hellesdon, 5 at Weybourne and one at Brancaster.  Also a caterpillar at the meadows in January 2020.

Scarce Footman Eilema complana - Recorded at home between 8th July and 7th August 2019 including a record count of 25 on 24th July.  After that I recorded it every night up to 7th August but apart from one on the last date I didn't count them on the other 13 nights.  I average 92 a year - with so many nights uncounted during their peak flight period it's impossible to know if 2019 was better or worse than that.  2020 was a good year, though not my best, with 131 between 17th June and 9th August.  Elsewhere 33 at the meadows (on 7 nights including 20 on 18th July 2020), 70 at Bintree Wood on 24th July 2020, 2 at Hellesdon, one at Brancaster and one at Weybourne.

Scarce Footman, North Elmham Cathedral Meadows, 7th July 2019


I sometimes come across pale washed-out examples that resemble Hoary Footman.  They're usually just worn but I tend to check them for Hoary just in case and so far they've always proven to be Scarce Footmen as expected.  On these worn examples the hindwings can look paler too, so I'd be wary of confirming a Hoary based on its hindwing colour.  The hindwings might be sufficient on some to confirm they are just Common (and so might a strong contrasting pale edge to the forewing?) but I often check the genitalia to make sure.  Hoary Footman is definitely a species worth looking for in Norfolk - it's spreading and there have been more records in Suffolk recently.  I can't imagine it will be long before we get them in Norfolk though I don't suppose the first ones are likely to turn up round here.

male Scarce Footman, North Elmham, 21st July 2020


Update 5-Apr-21: I originally posted a photo of a caterpillar here, from 23rd March 2019, which I thought might possibly be Scarce Footman.  I couldn't find any better options at the time but felt the orange dots weren't right and the hairs looked like they might be too long.  Finally the has penny dropped - it was in fact a December Moth.


Orange Footman Eilema sorocula - 2019 was a terrible year for this species - just a single record of one here on 1st June.  I've never had fewer than 8 here in a year before and the average is 13-14.  I had 10 in a single night in 2018!  2020 was better, if a little below par, with 10 between 19th May and 17th June.  Also one at Bintree Wood and 3 at Hills and Holes.

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.


Herald, North Elmham, 23rd April 2019


Herald, North Elmham, 5th April 2020



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.

Straw Dot, North Elmham Cathedral Meadows, 25th May 2019



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).

Snout, North Elmham Cathedral Meadows, 21st June 2019


Snout, North Elmham Cathedral Meadows, 22nd August 2019


Snout, North Elmham Cathedral Meadows, 23rd June 2020



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.


White Satin, North Elmham Cathedral Meadows, 18th July 2020



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.

Black Arches, North Elmham, 23rd July 2019

Black Arches, North Elmham Cathedral Meadows, 7th August 2019



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...

Gypsy Moth, Themelthorpe, caught by Sean on 18th August 2019



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.

Yellow-tail caterpillar, Titchwell, 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.

Pale Tussock, North Elmham, 22nd April 2019

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.
