MACROMOTH SPECIES ACCUMULATION OVER TIME IN A SOUTH CAMBRIDGESHIRE GARDEN: RECORDING METHOD CONTRIBUTIONS, INFERRED ORIGINS AND WIDER CONTEXT.

We report the results of a second six-year study of the macromoths in a village-edge garden in southern England. 121 additional species were recorded, mainly by light trapping, but also by daytime recording (including pheromones) or early stages. One-third were likely to be residents nearby and a few were migrants from overseas, but the majority were considered likely wanderers from more distant locations in England. Species previously identified as expanding or declining nationally generally showed similar patterns in our garden, but with a few striking exceptions. The rate of species addition with time showed no sign of levelling off and trapping when the night-time maximum temperature exceeded 20°C was identified as the most effective way to record low-frequency wanderers and thus add further species.
