The genus Cicadula has 11 species in
Fennoscandia, but on the Faroes only 1
species, which is easily recognized by the 4
black spots on the vertex. The colour is or-
ange-yellow or greenish-yellow. It lives on
lush meadows, but the hostplants are un-
known.
C. quadrinotata was first found by J.P.
Kryger in 1926 on the meadow in front of
what was then the Sanatorium (now the
High School) in Hoydalar. Sixty-six years
later we went out and looked for it on the
same meadow and were very pleased to
see, that it was still very numerous there.
But we also found the species elsewhere on
the Faroes in places with rich vegetation i.e.
with moderate to no sheep grazing, typical-
ly in the infield.
C. quadrinotata is widespread through-
out the Palaearctic and also common i Scot-
land, Norway and Iceland.
