Description


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 3: Nebs - subfamily Anomologinae I)

GELECHIIDS (GELECHIIDAE) (continued)


Subfamily ANOMOLOGINAE


House Neb Bryotropha domestica - 15 in the garden and one next door between 23rd July and 12th September 2019 and 25 between 17th July and 8th September 2020.  2019 was a fairly typical showing here but 2020 was my best ever (and included a record count of 5 on 5th August).

Cinerous Neb Bryotropha terrella - Recorded here on 43 nights between 14th June and 17th August.  I didn't count every night but assuming only one on those nights (it was probably more) the total was 140 (including a count of 15 on 16th July).  In previous years here the total counts have varied from 31 to 62 so this was an exceptional year.  2020 was good again with 119 over 43 nights between 3rd June and 20th August.  Elsewhere recorded next door, at the meadows (19 in total), Bintree Wood, Hellesdon and Weybourne.

Thatch Neb Bryotropha basaltinella - 5 in the garden moth trap between 24th July and 3rd September 2019 and 4 between 31st July and 21st August 2020.  These follow 5 in 2018 and a total of 5 between 2014 and 2016 which were the first 5 to be recorded anywhere in Norfolk.  Since 2018 this species has started to be recorded elsewhere (2 sites in 2018, another 2 in 2019 and a 5th in 2020) so I no longer have the monopoly of county records.  Presumably this represents a real increase rather than just better detection?

Dull Red Neb Bryotropha senectella - 5 in the garden moth trap between 16th and 27th July 2019 and 4 between 14th July and 8th August 2020.  They're fairly average totals for here.  Also one at the meadows on 26th July 2019.  Although this is a grade 2 (dissection not required) I think this can be a trickier species to be sure about than the grading suggests and normally check the genitalia for confidence.  Although my pre-dissection provisional IDs are usually correct I have mistaken these with other Bryotropha, so care is needed if you don't dissect them.

Dark Neb Bryotropha affinis - recorded here on 18 nights between 5th June and 8th September (not counted every night so no total count).  That's the equal highest number of nights since moving here but it hasn't varied a great deal from year to year so far.  31 over 14 nights between 26th June and 15th August 2020, my second highest total.  Also recorded next door and at the meadows in 2019.

Obscure Neb Bryotropha similis - One in the garden on 29th July 2020.  2019 was the only complete year in 6 where I haven't recorded this species here at all, although with only one most years (2 in 2016) it was bound to happen sooner or later.

Heather Neb Aristotelia ericinella - None.  I've not found this species locally yet but it has been recorded fairly close so it might pop up one day.

 
White-bordered Neb Isophrictis striatella - One in the garden trap on 1st August 2019, the third consecutive year I have recorded one here.  None in 2020.
