The journey by ship from North America to New Zealand usually takes about a month to complete, going from the Northern Hemisphere to the Southern Hemisphere. Brown marmorated stink bugs (Halyomorpha halys) can end up overwintering in goods being transported, for example inside shipping containers departing the Northern Hemisphere in the late autumn. A concern is that the bugs can become active by the time they reach New Zealand during summer in the Southern Hemisphere. In recent years, a number of ships from different parts of the world have been turned away from docking in New Zealand because stink bugs were found. (Photo credit: Rob Morrison, Ph.D.)
