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.

male Beech Pigmy Stigmella hemargyrella, North Elmham, 30th August 2020

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.

Eyed Hawk, a new froghopper and other bits and pieces

There were no stand-out highlights in the moth trap on 3rd September, though an Eyed Hawk-moth is always nice, especially after things have slowed down in the autumn.  The others were Light Brown Apple-moth Epiphyas postvittana, Garden Rose Tortrix Acleris variegana, 3 Common Marbles Celypha lacunana, 4 Common Grass-veneers Agriphila tristella, Elbow-stripe Grass-veneer Agriphila geniculea, Common Plume Emmelina monodactyla, 2 Brimstone Moths, 2 Light Emeralds, 12 Large Yellow Underwings, Lesser Yellow Underwing, 3 Setaceous Hebrew Characters, Square-spot Rustic, Nutmeg, 3 Common Wainscots, 5 Flounced Rustics, Rosy Rustic and Straw Dot.

There was also a Hornet and the following caddisflies: Hydropsyche pellucidula, Hydropsyche siltalai, Limnephilus auricula and 7 Limnephilus lunatus.

Moth trapping at the meadows the following night produced a reasonable variety for this late in the  season: Brown Rowan Argent Argyresthia semifusca, White-shouldered Smudge Ypsolopha parenthesella, 2 Common Marbles Celypha lacunana, Bramble Shoot Notocelia uddmanniana, Water Veneer Acentria ephemerella, 2 Ringed China-marks Parapoynx stratiotata, 2 Chinese Characters, Blood-vein, Dark-barred Twin-spot Carpet, Common Carpet, Yellow Shell, Sharp-angled Carpet, 3 Brimstone Moths, Dusky Thorn, Common Wave, Light Emerald, 4 Flame Shoulders, 3 Large Yellow Underwings, Lesser Yellow Underwing, Broad-bordered Yellow Underwing, 2 Lesser Broad-bordered Yellow Underwings, 2 Setaceous Hebrew Characters, 35 Square-spot Rustics, White-point, Brown-spot Pinion, 4 Centre-barred Sallows, Vine's Rustic, Spectacle, Straw Dot and 2 Snouts.

At home that night Pine Carpet was new for the year.  Other highlights were Beech Pigmy Stigmella hemargyrella and Thatch Neb Bryotropha basaltinella. The former was my third this year of a species I hadn't previously recorded here and the latter was my fourth this year of a species that until this year hadn't been recorded anywhere else in Norfolk.

By recent standards 32 species in a night was excellent - the rest were Garden Midget Phyllonorycter messaniella, Beech Midget Phyllonorycter maestingella, Clover Case-bearer Coleophora alcyonipennella, 2 Little Dwarfs Elachista canapennella, Barred Fruit-tree Tortrix Pandemis cerasana, Light Brown Apple-moth Epiphyas postvittana, 7 Common Marbles Celypha lacunana, 4 Common Grass-veneers Agriphila tristella, 6 Elbow-stripe Grass-veneers Agriphila geniculea, Chequered Grass-veneer Catoptria falsella, 2 Ringed China-marks Parapoynx stratiotata, Common Plume Emmelina monodactyla, 4 Blood-veins, Grey Pine Carpet, Green Carpet, 5 Brimstone Moths, Dusky Thorn, 3 Light Emeralds, 13 Large Yellow Underwings, 2 Lesser Yellow Underwings, Setaceous Hebrew Character, 4 Square-spot Rustics, Nutmeg, Angle Shades, Flounced Rustic, 4 Vine's Rustics, Burnished Brass, Straw Dot and 4 Snouts.

Mayflies and lacewings were 3 Pond Olives Cloeon dipterum, Cunctochrysa albolineata and Hemerobius humulinus.

There were very large numbers of caddisflies in the trap, though no unusual species among them: 10 Hydropsyche pellucidula, 3 Mottled Sedges Glyphotaelius pellucidus, 13 Limnephilus auricula, 3 Limnephilus flavicornis, 46 Limnephilus lunatus, 2 Limnephilus marmoratus and 3 Limnephilus sparsus.

Not much else noted - Forest Bug, the sexton beetle Nicrophorus investigator, 5 Hornets and a Common Frog.

The following night the leafhopper Kybos betulicola appeared in my study

In the moth trap there were two new moths for the garden year-list, Brown-spot Pinion and Lunar Underwing.

Moth numbers continued to dwindle with the following on 6th: Garden Rose Tortrix Acleris variegana, Barred Marble Celypha striana, Common Marble Celypha lacunana, 2 Elbow-stripe Grass-veneers Agriphila geniculea, Ringed China-mark Parapoynx stratiotata, Single-dotted Wave, Brimstone Moth, 5 Large Yellow Underwings, 5 Lesser Yellow Underwings and Setaceous Hebrew Character.  There was one mayfly (Pond Olive Cloeon dipterum), one beetle (Bradycellus verbasci) and these caddisflies: Hydropsyche pellucidula, Mottled Sedge Glyphotaelius pellucidus, Limnephilus flavicornis, 6 Limnephilus lunatus and Limnephilus sparsus.

Next day a walk round the meadows produced a few insects including Migrant Hawker, Common Darter, Small Copper and Comma.

A White-shouldered Smudge Ypsolopha parenthesella was the only adult moth found but vacated leaf-mines of Scrubland Pigmy Stigmella plagicolella and 2 Apple Leaf-miners Lyonetia clerkella were also seen.

Other insects included 2 7-spot Ladybirds, the hoverfly Myathropa florea, a Turnip Sawfly and lots of wasps feeding on ivy.  They included lots of Common Wasps, at least one German Wasp and 2 Hornets, but among them I had brief views of a Colletes bee which was very probably an Ivy Bee.  Ivy Bee was new to science as recently as 1993 and arrived in the UK in 2001, reaching Norfolk by 2014.  It is now common in many places but as hard as I tried to find one at the meadows this autumn this brief sighting was the nearest I got.  Sadly it wasn't quite good enough to be 100% sure - I believe there are one or two other Colletes species that can visit ivy at this time of year and my views were not sufficient to rule out one of them.

Shaking some Field Maple keys produced the barkfly Ectopsocus briggsi, a harvestman and 2 spiders.  The latter were I think immature, or at least I could not see enough detail in their epigyne to be able to match them to any species, but I think they were an Araniella sp. and a Philodromus sp.  My references on harvestmen are sparse but from searching the internet I'm pretty sure this one was Paroligolophus agrestis, a species I hadn't previously identified.

2 Sallows were new for the year the following night.
