Weather conditions: Largely overcast and mild.
Trapping time: 18:15h - 20:15h

Additional notes: The evening produced a record count of March Moth, beating the Reserve's previous highest total of seven. There were earliest ever records of Yellow Horned, Oak Beauty, Satellite, Clouded Drab, Common, Small and Twin-spotted Quaker. This was almost certainly due to the unseasonably warm daytime temperatures, the county is  experiencing.
