Cerodontha scirpi (Karl, 1926)
Very long upper-surface corridor, in the end about 1/3 of the width of the leaf. The mine usually begins about halfway the blade and descends generally to within the leaf sheath, rarely just above. Just before pupation all frass is deposited in one big mass. Puparium within the mine, where it also passes the winter.
Cyperaceae, narrowly oligophagous
Bolboschoenus maritimus; Scirpussylvaticus.
S. sylvaticus is the main hostplant.
Not known from the Benelux countries (Fauna Europaea, 2007).
distribution within Europe
From Scandinavia to Germany, and from the UK to Lithuania and Hungary; also Bulgaria (Fauna Europaea, 2007).
Described by de Meijere (1928a, 1937a), Nowakowski (1973a) and Dempewolf (2001a). Front spiraculum very large, bifid, with 24-30 papillae. Rear spiraculum large as well, with 3 hook-like papillae. Body yellow.
anterior spiraculum (left) and rear spiraculum;
from Nowakowski (1973a)
Strongly depressed with deep intersegmental incisions; the colour ranges from yellowish brown to reddish brown (Karl, 1926a; Nowakowski, 1973a).
Dizygomyza, Phytobia scutellaris: auct. The host plant of Cerodontha scutellaris (von Roser, 1840) is unknown, probably a Carex; all references to Scirpus as a host relate to C. scirpi [Nowakowki, 1973a]).
Member of the subgenus Butomomyza Nowakowski (1973a).
