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.

A very late Lesser Broad-bordered Yellow Underwing and a couple of late migrants

The highlight on Guy Fawkes Night was a Variable Smudge Ypsolopha ustella, my first here and only my fourth ever.

The weirdest record this night was a Lesser Broad-bordered Yellow Underwing, a common species but one that normally stops flying at the end of August.  I checked the wing pattern and genitalia carefully to rule out Langmaid's, not that that's a late speices either.

Good to see one late migrant - even if it was only a Diamond-back Moth Plutella xylostella.

Other moths that night were 2 Narrow-winged Greys Eudonia angustea, Common Marbled Carpet, 2 Pale November Moths, November Moth agg., 4 Feathered Thorns and 5 Sprawlers.

The next few nights were a bit more ordinary:
  • Narrow-winged Grey Eudonia angustea, December Moth, Pale November Moth, November Moth agg., 9 Feathered Thorns, Mottled Umber, 3 Sprawlers and Green-brindled Crescent on 6th;
  • December Moth, November Moth, Pale November Moth, Feathered Thorn and 2 Sprawlers on 7th;
  • Ashy Button Acleris sparsana, 5 December Moths, November Moth, 2 Pale November Moths, 4 Feathered Thorns and Yellow-line Quaker on 8th;
  • Common Plume Emmelina monodactyla, December Moth, Feathered Thorn, Setaceous Hebrew Character, Sprawler and Dark Chestnut on 9th.

The first December Moth on 8th seemed very small, and when I found the second and put them side-by-side the size difference was remarkable.  The second was in fact a bit larger than most as you can see when all 5 are in a row (they're the 3rd and 4th from the left in the second photo).

The next 3 nights' catches all consisted of Sprawlers and one other species.  On 10th November it was 5 Sprawlers and my first Scarce Umber of the year.

11th was single Sprawler and Yellow-line Quaker and on 12th it was my first Rusty-dot Pearl Udea ferrugalis of the year and 2 Sprawlers.  Nice to get a migrant so late in the year.

The Sprawlers were my last of the year (assuming I don't get any late ones) and brought the total for the autumn to an incredible 60 individuals.

Just one Mottled Umber on 13th and Satellite and Chestnut on 14th.  So few moths you'd think it was mid November already...

I was a bit surprised to find a leafhopper in the trap on 14th, with it being such a cool night.  Having eliminated some similar species on wing-venation I'm pretty sure it's Eupteryx filicum, a new species for me.

A Rusty Oak Button Acleris ferrugana, on 15th November was the only one of these I've had this autumn.  Also Feathered Thorn and Setaceous Hebrew Character.

A Chestnut was the only moth on 16th.
