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: Gelechiids (Gelechiidae) (Part 6: Groundlings - subfamily Gelechiinae II)

GELECHIIDS (GELECHIIDAE) (continued)


Subfamily GELECHIINAE (continued)


Pointed Groundling Scrobipalpa acuminatella - Singles in my garden trap on 18th April, 1st June and 23rd July 2019 and 14th June and 17th July 2020.  I've had up to 4 of these here each year except 2015.  Elsewhere what I'm pretty sure was this species at the meadows on 22nd April 2019 (but it escaped in my study and this species requires confirmation by gen detting to be officially recorded) and one on Mull in June 2019.

Sea-blite Groundling Scrobipalpa suaedella - Of 15+ similar-looking Scrobipalpa at Brancaster on 2nd July 2020, 3 were retained and confirmed to be this species.

Sea-aster Groundling Scrobipalpa salicorniae - Dave Norgate asked me about a Gelechiid he'd taken at home (Toftwood, Dereham) on 26th July 2019.  It looked really interesting - apparently a Scrobipalpa, and suspiciously similar to salicorniae.  But this is a pretty rare species even in its saltmarsh habitat with none recorded in the county since 2 in 2004.  Indeed there haven't been any other records since I was born in 1971.  So the odds of the next one turning up far inland in Toftwood seem remote to the extreme.  Surely it wasn't this.  But if not, the other similar species are mainly coastal and/or extremely rare, so this one had to be resolved and I agree to give it the chop.  And sure enough, it WAS salicorniae!  Wow!  What an amazing record!  I was pretty impressed with my 2018 record of the equally saltmarsh-specific (but much commoner) Saltern Groundling Scrobipalpa instabilella here in North Elmham, but this record tramples all over mine!

Saltern Groundling Scrobipalpa instabilella - None.  Being a saltmarsh species this isn't something I'd expect to see locally, but nevertheless I did get one in my garden trap in 2018.


Goosefoot Groundling Scrobipalpa atriplicella - One at the meadows on 25th May 2019 was very unexpected.  Until recently there was just a single old record from 1874 in Norfolk but then Graham Geen caught 2 in Methwold in 2017, followed by another 5 in 2018 and 29 (!) in 2019.  Another 3 recorders found the species at different locations in 2019 too, so it would seem that this species is undergoing a dramatic change in fortunes in Norfolk at least.

Winter Groundling Scrobipalpa costella - Singles here in the garden on 16th August 2019 and 19th October 2020.  I've recorded this species here twice before (2016 and 2018).  Also one at Tresidder in Cornwall in October 2020.

Narrow Groundling Caryocolum alsinella - One at Brancaster on 2nd July 2020 was a nice surprise, a new moth for me and only the 8th county record.

Mouse-ear Groundling Caryocolum fraternella - Caught in the garden on 1st and 4th August 2020 but not in 2019.  I've had it here on 4 occasions before.  Also one at the meadows on 4th August 2019 and 18th July and 7th August 2020.

Short-barred Groundling Caryocolum blandella - None.  I've never seen this species but although it's scarce there are a few records including in mid Norfolk, so I think there's a good chance it will turn up here (or at least at the meadows where there is plenty of Greater Stitchwort, its foodplant).


Three-colour Groundling Caryocolum tricolorella - One to light at Swanton Great Wood was my first ever of this species.
