Food Plant: Larix decidua (Larch)

Mine: July to October, feeding again from April to May.

Notes: Larva mines leaves for the first two instars, until the case is formed. Spring feeding is from the case in which it over winters. The full-grown case is shown and is unvalved, 5mm long. The larvae can cause damage to larches in some years, by blanching the leaves (even causing death of the tree).
