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: Pigmies (Nepticulidae) (Stigmella part 2)

PIGMIES (NEPTICULIDAE) (continued)


Red Elm Pigmy Stigmella lemniscella - None.  I've not found this species yet but it's common and widespread enough so hopefully I'll find it sooner or later.


Golden Pigmy Stigmella aurella - A male just above some Brambles (but beaten from an Oak tree) at the meadows 11th September 2019.  Also some mines at the meadows belonging to this species in both years, and in the Lakes in 2019.

Glossy Bramble Pigmy Stigmella splendidissimella - None.  Common and widespread enough to mean I should have a fair chance of finding it locally.


Grey Apple Pigmy Stigmella incognitella - None, but previously recorded in my garden (in 2017).


Least Thorn Pigmy Stigmella perpygmaeella - Single males netted at the meadows on 27th April, 3rd May and 9th May 2020, my first examples of this species.

Beech Pigmy Stigmella hemargyrella - Singles in my garden moth trap on 4th August 2019 and 30th August 2020.  Also a probable on 7th August 2020, keyed to this species but I damaged the genitalia during the preparation so wasn't able to confirm it.  I had 3 here in 2018.

Barred Sycamore Pigmy Stigmella speciosa - None.  I've not found this species locally yet but it's common enough and there's Sycamore at the meadows so it should be plausible.


Base-spotted Pigmy Stigmella basiguttella - A male caught in my garden trap on 25th July and a female to light at Swanton Great Wood on 27th August 2019.  These are the first I have identified.  Also an occupied leaf mine at the meadows on 20th September.   None in 2020.

Red-headed Pigmy Stigmella ruficapitella - a male caught in my garden trap on 24th June 2019.  The minimal extent of blackish androconial hair-scales on hindwing helped to secure the ID of this one, a new moth for me.  Also mines at the meadows in September 2019 and November 2020.

Black-headed Pigmy Stigmella atricapitella - A male caught in my garden on 26th July 2020 was new for the garden but followed by 2 more on 7th August.  Although these were gen detted, the blackish androconial hair-scales on the hindwing also help to secure the ID.

Chestnut Pigmy Stigmella samiatella - A male caught in my garden on 25th May 2019.  I had caught 5 of these here in 2018 and 2020 saw a return to this form with 5 between 20th May and 20th August.

Common Oak Pigmy Stigmella roborella- Singles caught in my garden on 1st June 2019 and 10th August 2020 (plus an unconfirmed probable in July).  I had 2 here in 2018.  Also one at the meadows on 17th May 2020.
