Caloptilia hemidactylella (Denis & Schiffermüller, 1775)
Acer campestre, Amsterdam: mine and three stages of leaf roll, all of the same shoot
the lower surface mine
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.
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).
