mine
Oviposition at the leaf underside, generally in the axil of the midrib and a thick lateral vein. The very first part of the mine is so strongly contorted that sometimes a tiny secondary blotch originates, filled with black frass. Then follows a straight corridor of maximally 15 mm, almost completely filled with frass, mostly closely following a vein. Just before the larva is about to leave the mine (through an exit hole in the leaf underside) it turns away from the vein (Langmaid ao, 2007a).
hostplants
Ulmaceae, monophagous
Ulmus glabra, x hollandica, laevis, minor.
phenology
Bivoltine. Larvae in July and September-October (Hering, 1957a); adults in April – May and again in July (Langmaid ao, 2007a). Hibernation as pupa.
BENELUX
BE recorded (Snyers, 2008a).
NE recorded; see below
LUX not recorded (Fauna Europaea, 2007).
distribution within Europe
Germany, Central and Eastern Europe. In 2007 recorded in the UK (Langmaid ao, 2007a), and recognised in the Netherlands.
larva
Dull, transparent yellowish; older larvae live free at the leaf underside, causing window feeding.
pupa
Described by Patočka (1996a), Patočka & Turčáni (2005a). The dark blackish brown pupa lies in a grey-black, ribbed cocoon (Langmaid, Porter & Collins, 2007a).
notes
Bucculatrix albedinella and ulmifoliae were considered synonymous in the Netherlands until now. The publication of the paper by Langmaid ao occasioned a re-inspection of the Dutch material of “B. albedinella”. It consisted for a large part of ulmifoliae.
