Encyclopedia
The Nut Leaf Blister Moth (Phyllonorycter coryli) is a moth
of the Gracillariidae
family. It is found most of Europe
, except the Balkan Peninsula.
The wingspan
is 7-9 mm.
The larva
e feed on Corylus avellana
, Corylus colurna, Corylus maxima and Ostrya carpinifolia
. They mine
the leaves of their host plant. They create an upper-surface silvery tentiform mine. At first, the mine remains quite flat, and has the appearance of a blotch mine. At the end, the leaf is strongly contracted. There may be several mines in a single leaf. The pupa is made in a cocoon in a corner of the mine. The frass
is deposited in the opposite corner.
