< back | next >
the larvae initially mine the leaves

Food Plant: Fraxinus excelsior (Ash)

Egg: laid on a twig

Mine: October - June

Notes: In October mines the leaf (as shown). The larva is yellowish, with a black prothoracic and anal plate. 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.

National Status: Common
