Caloptilia hauderi (Rebel, 1906)
The mine begins as a lower-surface corridor then widens into a blotch; here all leaf tissue except the veins is consumed. Later larval stages live free in three, consecutively larger, leaf rolls of downfolded leaf segments.
Acer campestre, pseudoplatanus.
Larvae in May – June (Hering, 1957a).
BE recorded from Belgium by J & W De Prins & Jacobs (2005a), but the identification is disputed by Langmaid ao (2011a) and is retracted by De Prins & Steeman (2011a).
NE not recorded (Fauna Europaea, 2011).
LUX not recorded (Fauna Europaea, 2011).
distribution within Europe
From Czechia to Italy, and from Britain to Romania (Fauna Europaea, 2011).
Body yellow, head yellowish white (Hering, 1957a).
Calybites, Gracillaria hauderi; Caloptilia, Gracillaria, pyrenaeella (Chrétien, 1908).
C. hauderi was considered a British species, among others by Emmet ao (1985a). However, recently it was discovered by Langmaid ao (2011a) that Caloptilia semifascia, another British species, did not have one, but two annual generations, the first one being what till then was believed to be hauderi.
