Distribution:Holarctic, Oriental, Neotropical ( Ozerov 2005).

Comments:At high altitudes S. neocynipsea can be highly abundant on cow pastures, but the species is rather rare in the Swiss lowlands ( Rohner et al. 2015). This trend is also represented in the data above. Similar observations from the British Isles suggest that S. neocynipsea prefers habitats at high altitudes ( Pont 1987a). In contrast to European populations, this species is much more common in North America,where it seems to take the ecological role of S. cynipsea ,which has never been recorded for the Nearctic Region.
