Aphanisticus emarginatus (Olivier, 1790)

Coleoptera, Buprestidae

mine

In plants with recognisable leaves oviposition primarily on the auricles, otherwise on leaf sheaths or stem. Oviposition site covered with a jet black shining drop of dried secretion. From here starts a shallow, winding corridor of 35-50 mm length and eventually ca. 1 mm wide. Usually the corridor first descends, finally turns up. At some points the corridor dives deeper into the plant tissue and is invisible for a short stretch. In these deepter sections, that generally are crammed with frass, moulting takes place. Frass yellow, initially fine grained, later coarser. Pupation in the mine in the final section of the corridor, which is widenend into a pupal chamber (Bilý, 2002a; Rennwald & Rennwald, 2002a).

hostplants

Juncaceae, monofaag

Reports of Carex or Eleocharis are dubious, unless it concerns observations from southern Europe (Schaefer, 1949a).
