Food Plant: Fraxinus excelsior (Ash)

Egg: laid on a twig

Mine: October - June

Notes: In October mines the leaf . The larva is yellowish, with a black prothoracic and anal plate (as shown). It then mines the bark of a twig and overwinters in this. In spring it bores out the terminal shoot - causing it to droop. A very common miner in much of the UK.
