Orchestes alni: occupied mine on Ulmus minor



Ulmus glabra, Duin en Kruidberg


Ulmus minor, Duin en Kruidberg: mine with cocoon

Orchestes alni mine

Ulmus minor, Castricum; generally, the blotch section is situated in the leaf tip, but this isn’t a fixed rule


Oviposition in the underside of the midrib; here an extensive scar remains visible. Form this point a full depth corridor runs towards the leaf tip, where it widens to a blotch. The apodous larva eventually pupates in a globular cocoon, made inside the mine. Because the mine is made at a time the leaf still is unfolding, the leaf can be strongly disfigured.

host plants

Ulmaceae, monophagous

Ulmus glabra, laevis, minor.

Preference for U. minor (Rheinheimer & Hassler, 2010a).

The reference to Quercus pubescens by Blanes-Dalmau ao is a mistake.

BE recorded (Curculionidae.be).

NE recorded (Heijerman, 1993a).
