March of the armyworm

Armyworms are ravenous. They decimate crops and will take a thriving vege garden down to stalks overnight. Then they’ll come inside and eat your houseplants. They’ve been in New Zealand a long time but this summer, they boomed—and an even hungrier cousin blew in from over the ditch.

Living World

Geography
