Plant Parasites of Europe

leafminers, galls and fungi

Leucoptera sinuella

Leucoptera sinuella (Reutti, 1853)

scotch bent-wing

Leucoptera sinuella mine

Populus x canescens, Nieuwendam

Leucoptera sinuella eggs

egg shells


Eggs are deposited on the upperside of the leaf, mostly in groups of 5-10, less often singly, generally along a vein; the empty shells are flat and shining. The snow-white larvae form large, upper-surface blotches in which a considerable larvae may be present, also because mines may coalesce. Pupation is external; exit slit in upper epidermis.

host plants

Salicaceae, oligophagous

Populus alba, balsamifera, canadensis, x canescens, carolinensis, gileadensis, nigra, tremula; Salix aurita, caprea, cinerea, x fragilis, purpurea.

The relation with Salix seems mainly to occur in Central Europe.


Larvae in June and September; hibernation as pupa (Emmet, 1985a; van Frankenhuyzen & Freriks, 1970a).


BE recorded (Phegea, 2009).

NE recorded (Kuchlein & de Vos, 1999a;, 2009).

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

Almost all Europe, except Ireland, the Balkan Peninsula and the Mediterranean Islands (Fauna Europaea, 2009).



Described by Patočka (2000a), Patočka & Turčáni (2005a). Pupation is solitary under a conspicuous white spinning in the shape of an H (van Frankenhuyzen & Freriks, 1970a).


Paraleucoptera sinuella; Cemiostoma, Leucoptera susinella (Herrich-Schäffer, 1855).


Counting the empty egg shells easily shows the size of the litter. It appears that litter size is less on small leaves, compared with large ones (Kagata & Ohgushi, 2001a).
