Neoleucopis atratula (Ratzeburg, 1844: 170;

Musca)

Type locality: Germany (NT ♂, CNC) .

This species is widespread in Europe, the Near East, and the eastern Palearctic, and has been introduced into Australia and New Zealand, Argentina, and in several parts of North America. This species was among the predators introduced and established for biological control of Adelges piceae attacking true firs, Abies spp., in North America (Humble 1994). Rearing indicates that Adelges piceae is a primary host for this species. In addition, it is known as a predator of species of Pineus (such as Pineus strobi) infesting species of Pinus, and of other species of Adelges infesting species of Abies . The species has been collected from canopies of Scots pine, Pinus sylvestris (Thunes et al. 2004) .
