Cerodontha denticornis (Panzer, 1806)

mine

Mine begins as a narrow, usually upper-surface, occasionally lower-surface or interparenchymatous corridor in the blade, that descends towards the ligule, thence continues into the leaf sheath, generally at its inside. Usually only one mine per leaf. Puparium in a pupal chamber at the margin of the leaf sheath.

Neither mine nor larva can be distinguished from that of C. fulvipes that, as far as known, lives exclusively on Poa trivialis (Nowakowski, 1973a).

host plants

Poaceae, widely oligophagous

“Agropyron”; Alopecurus pratensis; Arundo donax; Avena; Calamagrostis arundinacea, epigeios; Dactylis glomerata; Elytrigia repens; Holcus lanatus, mollis; Hordeum vulgare & subsp. distichon; Lolium; Phalaroides arundinacea, Phleum pratense; Poa; Schedonorus giganteus, pratensis; Secale cereale; Triticum aestivum.

Hering (1957a) also mentions Phragmites australis, but Nowakowski doubts this.

notes

Member of the subgenus Cerodontha (Nowakowski, 1973a).

There are no reports of damage by this species, but it is very common in grasslands and cereal fields, and therefore a potential danger (Dempewolf, 2004a).
