This species is widespread in Europe, and has been introduced into Hawaii, and the eastern and western parts of North America. For Hawaii, although a small percentage of the vouchers from these releases are this species, most turned out to be N. tapiae . This species was also among the predators introduced and established for biological control of Adelges piceae attacking balsam fir, Abies balsamea , in North America. It is known to attack various species of Adelges infesting species of Abies , and less frequently species of Pineus infesting Pinus .
