The seasons are in a muddle!

A pristine Coronet was the most remarkable catch of the night: it is usually single brooded
from late May to early August with the previous latest Carms record from 21/8/2012.

Conditions were pretty ideal last night, with a light southerly airflow and overcast skies.  Over 180 moths of 25 species came to my MV at Cnwc y Llwyn (Brechfa), including the 4 commonest migrant species: 10 Udea ferrugalis, 2 Nomophila noctuella, 1 Dark Sword-grass and 1 Silver Y.  I checked the three Flame Shoulder carefully in case of the migrant Radford's FS which is having a record year in Britain, but no such luck.

Spruce Carpet dominated the catch, with 75+ individuals, and there were at least 30 Epirrita sp.  Otherwise there were good counts of most common autumn moths, such as 19 Flounced Chestnut, 13 Black Rustic, 12 Yellow-line Quaker, 9 Merveille du Jour and 8 Feathered Thorn.  Four moths appear to represent atypical 2nd/3rd generations: pristine Coronet, Red Twin-spot Carpet, Pseudargyrotoza conwagana and Scoparia ambigualis.

I'm pretty certain this is Scoparia ambigualis (poor photo) because
orangey brown tones were visible around the stigmata and the pale postmedian line is jagged near the dorsum


  1. What a haul, Sam! They've obviously been waiting patiently for your return!

  2. Yes indeed Steve, I thought that I did well last night with 60-odd individuals. Sam's obviousy got the mothing equivalent of green fingers!

  3. That really is a great late-October catch, with yet more wacky out of season records. Looking like another fascinating end of season run, though it will have to be a bit better to beat the end of last year.
