Cerodontha scirpi (Karl, 1926)

mine

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.

hostplants

Cyperaceae, narrowly oligophagous

Bolboschoenus maritimus; Scirpussylvaticus.

S. sylvaticus is the main hostplant.

BENELUX

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).

larva

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.

synonyms

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]).

notes

Member of the subgenus Butomomyza Nowakowski (1973a).
