Specimen labels

This species is characteristic of lowland sandy heath in North Europe. Nests are in the ground, often with low earth mounds and carton lined chambers. Flight period August. Fertilised queens start colonies through adoption by established nests of Lasius alienus, Lasius niger or Lasius psammophilus. Males which have well toothed mandibles have been seen to pick up objects and to feed themselves (Collingwood, 1979).

At a Glance • Temporary parasite  



Collingwood (1979) - Clear yellow; pubescence on head rather dilute but close and very fine on gaster. Funiculus segments distinctly longer than wide; scapes and tibiae elliptical in cross section with thin front edge. Petiole sides straight to weakly convex, dorsal margin flat to slightly emarginate. Body and appendage hairs numerous. Length: 3.5-5 mm.

Resembles Lasius umbratus but the different habits, flat appendages and rectangular scale in the queen, shining darker colour and fine sculpture in queen and male clearly distinguish the species from L. umbratus, although workers may be less easy to separate.


Spain to Japan, ltaly to Scandinavia (Collingwood 1979).
