reason S. wuestneii and S. flavens, are probably
distributed over a greater part of Norway. S.
wuestneii is known from North- and Central
Europe and North America (Canada and Alaska)
(Viitasaari & Vikberg 1985, Lacourt 1999).

One ♀ was captured in a meadow at AK Oslo:

E. gagathinus is a black and shining sawfly (5–7
mm.) with yellow legs and smoky wings. E.
gagathinus is widely distributed all over Europe,
44
including Denmark and Finland (Viitasaari &
Vikberg 1985, Benson 1952, Nielsen & Henriksen
1915). The distribution in Norway is uncertain,
but the species is probably not common. The host
plant is unknown, but other species in the genus
feed on different species of Poa, Juncus and Carex
(Taeger et al. 1998) which might be host plants for
E. gagathinus as well.
