Nematus stichi (ENSLIN, 1913)

Im Scotland only recorded previously from Lanarkshire ( Benson 1958).

Nematus sp. cf leionotus

Some of these specimens were swept from an unidentified Salix sp. (or spp.).

Perhaps this taxon is one of the several ‘brown’ Nematus described by Lindqvist from northern Europe. These taxa are in need of revision. Compared to female N. leionotus this unidentified species is: more extensively dark marked, particularly the upper head; lateral lobes of mesonotum more heavily sculptured; provisionally associated with Salix rather than Betula [ N. leionotus ] and found later. N. leionotus is found only at or a few days after flushing of its host, while the birches on and below crags at Meall nan T. were in full leaf when N. sp. cf leionotus was taken.
