Much varying in colour: the males get pro-
gressively darker with age and occasional-
ly completely black or even ultramarine
(when alive) specimens can be found. The
females can vary from unicolorous light to
almost black. The males are usually sub-
brachypterous, while the females are
brachypterous.
S. sordidus is found everywhere where
the vegetation is lush i.e. it is a typical
leafhopper of the infield in ditches and
fields used for haymaking. It is widespread
in Europe and also found in Scotland and
Norway. It is perhaps surprising that this,
the most common leafhopper on the
Faroes, is not found in Iceland while the
most common Icelandic leafhopper (Jas-
sargus distinguendus Flor), which is also
found in Scotland and southem Norway, is
not found on the Faroes.
