Several species of honeysuckle have become invasive when introduced outside their native range, particularly in New Zealand and the United States. Invasive species include L. japonica, L. maackii, L. morrowii, and L. tatarica.ost honeysuckle berries are attractive to wildlife, which has led to species such as L. japonica and L. maackii spreading invasively outside of their home ranges. Many species of Lonicera are eaten by the larvae of some Lepidoptera species â see a list of Lepidoptera that feed on honeysuckles.
