Norfolk moths: Rockland St. Peter garden, 14 September 2013

The night of 14 September was crystal clear, cloudless, dead calm and fine. As a consequence, temperatures dropped markedly overnight: from the low teens at dusk to 7.8°C when I first checked the trap at 05h30,  4.2°C when I turned it off at 06h10 and 3.9°C by 06h30.

Not surprisingly, the catch was much reduced and for the first time there were neither micros, nor wasps nor carrion beetles. Golden Plover were calling high overhead as I patrolled the trap in the pre-dawn.

Lunar Underwing was new for the trap, with two strkingly different colour forms.

Lunar Underwing Omphaloscelis lunosa: variations on a theme.

Common Marbled Carpet Chloroclysta truncata: this strking colour form is the only one trapped so far.

Rockland St. Peter: more Golden Plover flying south

Another flock of c. 250 Golden Plover flew SW, just after midday. Whistled imitations caused the birds to swirl around high overhead for a minute or two, before they headed southward once again.

Norfolk moths: Rockland St. Peter garden, 11 September 2013

Last night, 11 September, was forecast to be the only fine night for the next few days, so I decided to give the trap an airing. Between my setting it up at dusk (19h45) and my check on activity at 21h00, a light drizzle had wet the white groundsheet and peppered the perspex. But that was probably the only rain of a night which was cool (though a degree or two warmer than preceeding nights), darkly overcast and dead calm. The temperature on checking the trap at 05h15 was 12.5°C.

The catch was up on the previous one. I finally caught my first Nutmeg, and the other new one for the trap was the common Antler Moth.

The first Nutmeg Discestra trifolii.

Canary-shouldered Thorns always brighten up a dull morning - and they're good with people too...

Norfolk moths: Rockland St. Peter garden, 4 September 2013

The night of 4 September was fine and cloudless, yet warm (a min. of perhaps 16°C?), with a very light breeze that had dropped off by the pre-dawn.

Of the four nights I have run the new trap so far, this was the most diverse, with some 35 species of macro moth. A nice big Bulrush Wainscot was the first out, but this was the night of the carpets, with six species, including a lovely fresh Green Carpet, two ginger-coloured Common Marbled Carpets and a neat Purple Bar.


Bulrush Wainscot Nonagria typhae, one of the largest wainscots.

Norfolk moths: Rockland St. Peter garden, 2 September 2013

A fine night, with a breeze that dropped from moderate to light around dawn. Almost cloudless and relatively warm (min. 14°C?).

Pebble Prominent, while not a rarity, was nice to see. The trap contained quite a few Square-spot Rustic lookalikes, ranging from grey, to brown and rufous with worn individuals mixed in.

Moth of the night was Oblique Striped, a species whose stronghold in the UK is the Brecks and designated Nationally Scarce B (species that are nationally scarce and have been recorded in 31 – 100 ten kilometre squares in Great Britain).

Norfolk Bat Survey concluded

I just retrieved the BTO's recording equipment from the final point I had signed up to survey for the Norfolk Bat Survey. I would have like to have covered a couple of extra grid squares, but have been unable to get permission to locate the equipment overnight. Nevertheless, in a little over a month I have managed to cover nine O. S. grid squares in the Rocklands area - that's 27 detector-nights, each at a different location no closer than 200 m to its closest neighbour. This should give a fair idea of the variety of bats we are lucky enough to share this area with. Looking forward to receiving the final results from the BTO...
