Remarks
N. calmariensis and N. pusilla were introduced in the US from Europe and Asia in 1992 to control purple loosestrife. N. calmariensis emerges about a week before N. pusilla, first eating the leaves, shoots, and buds; then the N. pusilla eats the new growth, weakening the loosestrife, and after a few years the plants die off.
