The eggs of these caterpillars are laid by moths of about 40mm in length during the evening. Attacking the buds of various species these little caterpillars quickly damage new growth and are a dreaded find for rose growers. Juvenile caterpillars can also damage foliage leaving a paned effect on the leaves.
