Large Grey Scoparia subfusca - Caught in the garden on 30th July 2019 and 24th June 2020. I'd only caught 2 here before in the previous 4 years. Also one to light at the meadows on 30th June 2019.

Base-lined Grey Scoparia basistrigalis - 12-13 caught at home (1 escaped before I confirmed it) between 4th and 25th July 2019 and 9 between 24th June and 4th August 2020. 2019 was my best year to date - it averages 7 per year. Also 2 at Bintree Wood and one at Weybourne. Although this species no longer requires dissection for records to be accepted (it's grade 2) I don't think the ID is always that straightforward. Some are clear enough but a great deal of care is required - confusion with ambigualis is easy, especially with small or worn individuals (or large coarsely-marked ambigualis), and some even approach pyralella in appearance. I still tend to check the genitalia on any but the most obvious examples and they aren't always what I'm expecting them to be.

Common Grey Scoparia ambigualis - Totals at home of 68 between 16th May and 25th July 2019 and 50 between 20th May and 23rd July 2020. They were my worst year for this species so far - I had been averaging around 110 a year. Elsewhere 24 at the meadows, 11 at Bintree Wood, 3 at Hills and Holes and 3 at Weybourne. I generally identify these without checking their genitalia, but any that are too worn, or any that look a bit suggestive of one of the other species in some way, are confirmed.

Meadow Grey Scoparia pyralella - 5 in the garden between 7th June and 4th July 2019 and singles on 4th and 17th June 2020. The latter was my worst year here - there had been little variation 6, 5, 5, 4 and 5 in the previous 5 years. Elsewhere one at Brancaster on 2nd July 2020.

Little Grey Eudonia lacustrata - At least 185 between 15th June and 3rd August 2019 but probably more as not counted on several nights - a better year at least than the previous 3 at least. A reasonable year in 2020 too with 114 between 11th June and 19th August. Elsewhere 1-2 at the meadows on 7 dates, 7 at Bintree Wood, 6 at Weybourne and 4 at Hellesdon. This species is very variable and I find some individuals quite difficult to separate from mercurella, and tend to check a selection to make sure I'm recording them accurately (especially the darker ones which I find easiest to get mixed up).

Narrow-winged Grey Eudonia angustea - One at home on 5th May 2019 was my only record from the spring generation that year, a surprise after having 21 in spring/early summer 2018. In the more 'traditional' autumn generation numbers were more typical with a total of 177 between 22nd August and 31st October, a little under average (191). In 2020 there were 4 between 3rd and 16th June and 145 between 11th August and 9th November. None elsewhere in Norfolk - surely one of the most obvious gaps in the list of species recorded at the meadows - but 4 in Cornwall in October 2020 and 3 in NW Spain in February 2020.

Ground-moss Grey Eudonia truncicolella - 2 at Row Heath (West Runton) on 31st August 2019. None in 2020. Although common on heathlands this species can be hard to find elsewhere. I've not had a confirmed record here yet although a strong contender was caught here in 2017 (I couldn't quite 100% rule out mercurella from its worn external appearance and their male genitalia are rather similar. I may yet be able to resolve this if I ever remember to check whether male mercurella has a hamus or not - if it does then this was truncicolella).
Small Grey Eudonia mercurella - Trapped at home between 27th June and 14th August 2019 with at least 52 individuals (not counted every day). That's pretty comparable with the previous 3 years (although I recorded more in 2015 I have a suspicion that the odd incorrectly identified moth may have slipped in back then). 66 here between 15th June and 18th August 2020. Elsewhere found next door, at the meadows and at Row Heath (West Runton). Some of these look very much like lacustrata to my eyes and since realising I may have been mis-assigning some I have increased the proportion that I check genitalia.

Marsh Grey Eudonia pallida - Totals of 12 caught at home between 4th June and 19th July 2019 (including a record 4 on 24th June) and 7 between 21st June and 28th August 2020. They're my highest and equal lowest totals in 6 years. Elsewhere recorded at the meadows on 4 dates between 31st May and 3rd September 2019 and at Weybourne and Whitwell Street.
