Plant Parasites of Europe

leafminers, galls and fungi

Caloptilia hemidactylella

Caloptilia hemidactylella (Denis & Schiffermüller, 1775)

sycamore slender

Caloptilia hemidactylella

Acer campestre, Amsterdam: mine and three stages of leaf roll, all of the same shoot

Caloptilia hemidactylella young mine

the lower surface mine

Caloptilia hemidactylella leaf roll

final stage leaf roll


The larva makes a relatively long, lower surface gallery, that widens into a blotch of 3-4 mm long, where all leaf tissue is consumed, leaving only the venation. Later larval stages live free, living in three, successively larger, leaf rolls made of downfolded leaf segments.

host plants

Sapindaceae, monophagous

campestre, platanoides, pseudoplatanus, saccharinum.


Larvae in July – August (Emmet ao, 1985a), but, at least in the Netherlands, there probably is another, earlier, larva generation (Corver ao, 2011a).


BE recorded (Phegea, 2011).

NE recorded (Corver ao, 2011a).

LUX recorded (Fauna Europaea, 2011).

distribution within Europe

Europe, except Iceland, Ireland and the Balkan peninsula (Fauna Europaea, 2011).
