Nephopterix angustella (Hübner, 1796)
on spindle, (sweet chestnut)
The larva bores in the fruits, moving from one fruit to the other. Silk connecting the fruits, bore holes and extruded orange frass betrays its presence. Pupation in an elongated white cocoon among the fruits or on the ground.
Celastraceae, ± monofaag
An observation by Roesler on Castanea sativa probably is exceptional.
Univoltine; hibernation as larva or pupa in the cocoon.
