A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

Review of 2019 and 2020 - Moths: Noctuids (Noctuidae) part 1: Plusias to Nut-tree Tussock

NOCTUIDS (NOCTUIDAE)


Spectacle Abrostola tripartita - Totals of 17 trapped here between 30th May and 29th August 2019 and 34 between 30th May and 22nd August 2020.  2019 was my worst year here since moving in (average 43 a year).  Elsewhere 4 at the meadows (from 25th May), one at Bintree Wood and 2 at Hellesdon.

Dark Spectacle Abrostola triplasia - One in the garden moth trap on 14th June 2020.  This was my 7th here since moving in in 2014 and 2019 was my first blank year.

Dewick's Plusia Macdunnoughia confusa - None.  I've never trapped this species but it's becoming so well established in Norfolk, including in parts of mid Norfolk, that it surely can't be long before it arrives here.


Burnished Brass Diachrysia chrysitis - Totals of 36 caught here between 18th June and 30th September 2019 and 19 between 21st May (my earliest ever) and 20th September 2020. The 2020 total was my worst in 6 years and both years were well below the average annual tally of 60.  Elsewhere 5 at the meadows, one at Whitwell Street and one at Hellesdon.

Silver Y Autographa gamma - Totals of 17 trapped in the garden between 3rd June and 19th September 2019 and 25 between 2nd June and 26th September 2020.  My average annual tally here is 16 and 2020's total was my highest yet.  Elsewhere 5 at the meadows, one at Bintree Wood, one at Row Heath (West Runton), 2 on Mull and 4 in Cornwall.

Beautiful Golden Y Autographa pulchrina - 5 caught at Carsaig (Mull) between 9th and 13th June 2019.  This species is quite irregular here - I caught one in 2015, 4 in 2016, none in 2017, one in 2018 and none again in 2019 or 2020.

Plain Golden Y Autographa pulchrina - None in 2019 but one in the garden moth trap on 4th July 2020.  I've only caught 3 of these at home before, in 2015, 2016 and 2018.

Gold Spot Plusia festucae - One to LEDs at the meadows on 31st May 2019.  I've caught this species at home twice, in 2015 and 2016.  I've never seen Lenpke's Gold Spot, though I have seen a couple of individuals that experienced moth recorders assured me were this species (but which I was doubtful about and on dissection they proved to be Gold Spots).

Marbled White Spot Deltote pygarga - 3 caught in the garden between 24th and 28th June 2019, the 3rd year out of 5 that I've caught 3 here - the other 2 years yielding 11 and 13.  None caught in the garden in 2020, my first blank year here, but singles at the meadows, Bintree Wood and Hills and Holes.

Silver Hook Deltote uncula - At least 2 seen by day at different points along the footpath from Carsaig to Rubha Dubh on Mull on 10th June (both in damp grassland immediately up from the beach).  None in 2020 - I've only ever seen one of these in Norfolk and it doesn't occur locally.

Nut-tree Tussock Colocasia coryli - In 2019, 5 caught here between 8th and 29th April then at least 22 between 12th July and 5th August (not counted on 4 dates but only singles on surrounding dates).  I averaged 55 per year over the previous 4 years - safe to say this was my worst year so far.  2020 was a bit better with 7 between 6th April and 18th May and 52 between 8th July and 6th August.  Elsewhere one at the meadows, 2 at Bintree Wood and 3 at Sculthorpe Moor.
