Quercus robur, Boswachterij Nuspeet © Hans Jonkman: identification based on the date: September 21

Caloptilia cf rbustella: free living larva

larva

mine

Mine indistinguishable from the one of C. alchimiella.

hostplants

Fagaceae, oligophagous

Fagus sylvatica; Quercus robur.

According to Biesenbaum (2010a) also Castanea sativa.

phenology

Occupied mines in May, then again in August; free living larvae until June, then September – October (Emmet ao, 1985a).

BENELUX

BE recorded (Phegea, 2010).

NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2010).

LUX recorded (Fauna Europaea, 2010).

distribution within Europe

Europe, except the Balkan Peninsula (Fauna Europaea, 2010).

pupa

See Patočka & Zach (1995a) and Patočka & Turčáni (2005a) for differences with C. alchmiella.

notes

Only pupae and adults always enable a certain identification. But mining larvae in May certainly are robustella. Moreover, according to Patočka & Zach (1995a) does alchimiella pupate in a white cocoon, robustella in a yellow-white one.

Seems more than alchimiella to be a species of xerothermic habitats (Kasy, 1979a).
