I have current bushes. Every year, one day in June, the cutworms emerge and strip all the bushes of the foliage in about 8 hours leaving nothing but bunches of red berries dangling from naked sticks. It doesn't kill the plants, but neither do they thrive. Still, it's the tent caterpillars that are the worst. They'll strip all trees and bushes in a 20 metre radius and some years there's a nest every 10 metres. Not good in an orchard.
