Norfolk moths: Rockland St. Peter garden, 1 April 2014

The day was fairly warm perhaps 15°C but the sun has been obscured over the past several days by a kind of smog, both local air pollution from the UK Midlands and dust blown in from the Sahara. The night began overcast with high, white cloud and a temperature of 9.6°C at 21h00 (an hour after I turned on the trap). There was a thin, waxing crescent moon and a very light E wind. By 05h00 it was calm and there appeared to be a mist in the air, much of which proved to be particulate. The temperature on turning off the trap at 06h00 was 6.4°C.

The catch was about half that of the previous night, the only new moth for the year being a fresh Spectacle, flying a couple of months ahead of schedule: "this moth is out in June, sometimes late May" (South 1908). A single Pale Pinion a different individual to the one caught at the weekend  rested on a nearby wall.
