To some finding that extra crispy, burnt-looking chip at the bottom of a bag can feel like finding a pot of gold at the end of a rainbow. Unfortunately, the real explanation behind these "zebra chips" is less harmless.
These chips are actually the victims of the tomato potato psyllid, a bug that feeds on crops, and three years ago wiped out nearly 6 percent of Canterbury's potato crop.
To prevent this happening again researchers at Lincoln University have been conducting research to target the bugs.
