Bucculatrix frangutella (Goeze, 1783)
Rhamnus frangula, Ede
Rhamnus frangula, Ommen: a single mine
Rhamnus frangula, Lage Mierde: windown feeding, caused by the free living larvae
Rhamnus frangula, Wolfheze: egg
A narrow corridor, densely wound, amost entirely filled with purplish brown frass. The last 1 to 2 cm of the corridor are free from te spiral, and almost straight. At this point the mine is left, and the larvae continue to live free on the leaf, causing window feeding. The emptly larval chamber, obviously free from frass, is conspicuousy slender. The egg, in the very centre of the spiral, is at the leaf lower side, as is the exit from the mine (Emmet, 1985a). Pupation in a greyish-brown, spindle-shaped, strongly ribbed cocoon.
Mines are found from July to November; according to Emmet (1985a) the larval stage is in June-July. Univoltine, hibernation as pupa (Patočka, 1996a).
BE recorded (De Prins, 1998a).
NE recorded (Microlepidoptera.nl, 2008).
LUX recorded (Ellis: Ahn, Palmberg).
distribution within Europe
Entire Europe, including Portugal and Spain, except the Balkan Peninsula (Baugnée in litt., 2012; Corley ao, 2006a; Fauna Europaea, 2008).
Described by Patočka (1996a), Patočka & Turčáni (2005a).

B. fragulella. Goeze’s original spelling of the specific name is frangutella. Given the name of the host plant, and the small difference between an l and a t in worm lead hand printing this obviously is a typing error and according to the rules of nomenclature frangulella should be the valid name. However, in Lepidoptera tradition it is customary to set side the rules of nomenclature at this point, and to rigidly adhere to the original spelling.
In some shrubs of Rhamnus catharticus the mines are surrounded by unusually large darkened spots.
