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.

Holkham moth night

A couple of unsuccessful attempts to see Great Knot at Titchwell produced 3 Diamond-back Moths Plutella xylostella (17th) and a Timothy Tortrix Aphelia paleana (18th).

At home 17th wasn't a great night with just 40 species, none of which were new for the year: 5 Diamond-back Moths Plutella xylostella, Light Brown Apple Moth Epiphyas postvittana, Yellow-spot Tortrix Pseudargyrotoza conwagana, Barred Marble Celypha striana, Common Marble Celypha lacunana, Triple-blotched Bell Notocelia trimaculana, 3 Hook-streaked Grass-Veneers Crambus lathoniellus, 2 Common Greys Scoparia ambigualis, 2 Narrow-winged Greys Eudonia angustea, 4 Small Magpies Anania hortulata, Common Swift, Treble Brown Spot, 3 Silver-ground Carpets, Garden Carpet, Small Rivulet, Foxglove Pug, Scorched Wing, Brimstone Moth, Willow Beauty, Light Emerald, Pale Tussock, Orange Footman, Common Footman, 5 White Ermines, 7 Buff Ermines, 5 Heart and Darts, Large Yellow Underwing, Ingrailed Clay, Setaceous Hebrew Character, Lychnis, Common Wainscot, Brown Rustic, 7 Marbled Minors, 2 Middle-barred Minors, 8 Treble Lines, Mottled Rustic, 3 Burnished Brasses, Beautiful Golden Y, 3 Straw Dots and 2 Snouts.

A new caddisfly, Athripsodes aterrimus, saved the night.  Other caddis included Limnephilus auricula, Limnephilus flavicornis, Limnephilus lunatus and 2 Limnephilus marmoratus.

On Saturday 18th I headed up to Holkham for the Norfolk Moth Survey event.  The forecast hadn't been great but it turned out to be cloudier than we'd expected, the wind had dropped right down and at first it didn't feel as cold as we'd feared.  But things seemed a bit slow anyway, despite several highlights.

I didn't get there early enough to do any dusking beforehand but those that did found and retained some New Holm-Oak Pigmies Ectoedemia heringella, the first time I've seen this species.

Surprisingly we saw more micro moths than macro, though slightly less variety according to my personal totals (which are always incomplete for events like this).  Apart from Common Grey Scoparia ambigualis, the most numerous micro was Large Groundling Teleiopsis diffinis, for which I estimated a dozen, followed by Beautiful Groundling Caryocolum marmorea (maybe half a dozen or more?).

Someone found a Small Saltern Conch Gynnidomorpha vectisana, a new moth for me.  I only saw it in a pot so my photos aren't worth sharing.  Another moth passed round in a pot was claimed as a Strophedra.  I didn't get a good enough look to challenge that but subsequently it turns out that it's probably Pine-cone Piercer Cydia conicolana.  I've not heard that it's been gen detted yet but assuming the ID proves correct then that's another lifer for me.  We also caught a Momphid which I wasn't able to identify on the night.  It was very worn and frankly looked nothing like the Little Cosmet Mompha raschkiella that it proved to be on dissection.  Surprisingly, as this is a much commoner and more widespread species, this was also a new moth for me.

The other micros were 4 Diamond-back Moths Plutella xylostella, Painted Neb Eulamprotes wilkella, Desert Groundling Bryotropha desertella, London Dowd Blastobasis lacticolella, Hedge Shade Isotrias rectifasciana, 3 Hook-streaked Grass-Veneers Crambus lathoniellus, Pearl Grass-veneer Catoptria pinella, 2 Little Greys Eudonia lacustrata, Narrow-winged Grey Eudonia angustea and Ochreous Pearl Anania crocealis.

Among the macros the highlight for me was 2 Pine Carpets - a species I've only seen once before.

Nothing else remarkable among the macros - the others I recorded were Common Swift, Cream Wave, 3 Silver-ground Carpets, 3 Green Carpets, Common Pug, 2 Clouded Borders, 2 Scorched Carpets, Brimstone Moth, Peppered Moth, Privet Hawkmoth, Buff Ermine, 12 Cinnabars, Archer's Dart, Shoulder-striped Wainscot, Brown Rustic, Treble Lines, Spectacle and 2 Straw Dots.

I think this beetle is the Marram Weevil Philopedon plagiatum.  Assuming my ID is correct then that's a new one for me.  Another new beetle that should be correct as Andy M gave me the ID was the Click Beetle Prosternon tessellatum.

The Caddisflies didn't turn up anything that I don't get at home: Phryganea grandis, 4 Limnephilus auricula and 4 Limnephilus marmoratus.

Back at home the moth trap wasn't exactly overloaded with goodies.  I didn't get any False Cacao Moths Ephestia unicolorella last year so this one was new for the house.

Riband Wave and Common Wave were new for the year here and the other moths recorded at home were 2 Barred Marbles Celypha striana, Common Marble Celypha lacunana, Hook-streaked Grass-Veneer Crambus lathoniellus, Small Magpie Anania hortulata, Common Swift, 2 Silver-ground Carpets, Common Marbled Carpet, Common Pug, Clouded Border, 2 Willow Beauties, Common White Wave, Elephant Hawkmoth, Common Footman, 2 White Ermines, 5 Buff Ermines, Cinnabar, 2 Heart and Darts, Ingrailed Clay, Brown Rustic, 4 Treble Lines, 2 Mottled Rustics, 2 Burnished Brasses and Straw Dot.  Limnephilus lunatus was the only caddisfly recorded.
