A "Malaise" trap in position on Otago's Old Man Range is being used to survey introduced and native Microctonus wasps. Flying insects land on the central vertical partition of the trap and then instinctively work their way up towards the light where they become caught in a preservative. The researcher in the background is using a commercial leafsucking machine to collect native weevils.
