Large means large

I am running a day behind these days, with daylight coming too slowly and too late for me to scribble out the blog post before life's other demands kick in. Today's handsome whopper therefore visited me on Sunday night and provided a nice surprise yesterday morning.

It's a Large Wainscot, suitable named as you can see when you compare it with the Common Wainscot which also stayed the night. Here they are below, waking up slowly in the company if a Merveille du Jour, that star of the UK's Autumn moths.

The Large Wainscot is not that common round here but it has come calling for the last three years. It likes watery spots and we have both the Oxford Canal and the River Cherwell nearby. A curiosity of its behaviour is that it flies twice a night, briefly at dusk and then for a longer spell later on. Superficially it resembles the White Speck which filled me with such joy yesterday, and inded my first thought on seeing the WS was that it was an LW.

I rhapsodised about the Green-brindled Crescent two days ago. Its appearance is usually followed by that if its very close relation, the form cappucino, and this has duly happened again this year. Here it is, above, a darker and less blingy version, with the brown body and creamy top associated with the coffee (and the Capucin monks after whom both drink and moth are named). The standard, glisteningly green form is on the left.

A distinctive micro next. This is is Hypsopygia glaucinalis, a sort of big brother to Hypsopygia costalis or the Gold Triangle, the pretty scrap of purple and gold which came the other day - and again in this bunch of Sunday nighters - see right. Glaucinalis is duller but bigger, easily the size of many UK macro moths. It's also useful. Unlike the Boxworm and White Speck (or Armyworm) which are serious crop and plant pests, its caterpillars feed on decaying matter and are useful scavengers. They have admittedly been found munching on birds' nests, but not in sufficient numbers to do serious damage. And it's hard to imagine them being foolhardy enough to dine on an occupied nest, whose inhabitants would surely seize the chance to dine on them,

When I first went to look at the trap, a small moth was all of a flutter inside the transparent collar, whirling around distractedly before finally settling on the battered plastic. Here's the view I had below:

What was it? I lifted the bulb and its holder out carefully and upturned the collar gingerly. The moth stayed put and posed for a picture, resting on my beautifully pyjama-glad knees (the jams looking a bit grubby because the collar is between them and the moth).  It's a Straw Dot, one of the macros smaller than Hypsopygia glaucinalis, which is enjoying a good long season this year.

Finally, a series of tortrix micros: a fine, fresh example of the Garden Rose Tortrix, Acleris variegana, which last arrived two nights ago in the form of a very battered specimen; the puritanically grey Acleris sparsana and the Light Brown Apple Moth, Epyphias postvittana, with a jauntily tail-cocking Red-green Carpet looking on.
