Norfolk moths: Rockland St. Peter garden, 6 October 2013

After a glorious warm, sunny day, the night of 6 October was cloudless and cool with neither wind nor moon. After a day-time high of close to 20°C, the temperature had dropped to 10.2°C by 21h00 and was 7.5°C when I turned off the trap at 06h30. The only sound in the pre-dawn was the call of a solitary Redwing, flying south - the first of the year for Rocklands.

The cool night reduced moth activity slightly. There was only one new species, the long-awaited Merveille du Jour, which is every bit the marvel its name suggests. It came in early: by 21h00 it was perched on the perspex entrance to the trap, just below the light. I gently nudged it into the trap, but by dawn it was back in its original spot, having escaped! This common species, whose larvae feed on oak buds, flowers and leaves, is probably new for me since I have not trapped into the autumn in the UK before.
