The Light Emerald is unrelated to the ten other Emerald moths - they are nearly 30 pages apart in the Moth Bible - but it shares a feature of the colour green. This fades faster than any other colour in the spectrum on moths. It is commonplace to find a bleached emerald moth after only a few weeks of its life. Older specimens in collections need to be preserved so far as possible from any light or their colour is lost for ever.
Another delightful visitor last night was this Marbled Coronet, below, a moth which is almost impossible to see on lichen or bark, hence my choice of my pyjamas as the background. I tried to entice the moth on to some lichen on a wall, to prove my first point, but it spotted a crack in the mortar and wisely scuttled into it and out of reach.
The next picture shows another newcomer for the year, a Heart and Club, and then we've a more familiar pair, a Peppered Moth in the background, behind a Spectacle, whose perky look I could not resist.
The immigrant Bordered Straw put in another appearance, below, and the regular Privet Hawk found a new resting position, gazing at the mercury vapour bulb in adoration from the neck of the trap's funnel.
Now for a little rogue's gallery of micros, which I will endeavour to ID. Left to right, top to bottom, I'm going for Barred Fruit-tree Tortrix (Pandens ceresana), Bud moth (Spilonota ocellana), Um, Er and finally Scoparia pyralella. Fingers crossed... Update: Trent kindly confirms these and fills in the missing one as Celypha lacunana (which I've often had and ought to recognise by now). Dave Wilton on Upper Thames Moths' blog, meanwhile, cautions that Scoparids are difficult to be sure of unless in fresh condition. As I say in my reply to Trent below, it's a tricky old business!
Lastly, I'm not sure what this is, below. A Square-spot Rustic with some scales missing? Update: Trent confirms SSR. Many thanks.
