larva feeding

Egg: underside of leaf

Mine: Sept-April

Notes: Initially makes a narrow gallery mine in late autumn of the first year then overwinters in the mine. In the spring of the second year,in late April or May, it forms a blotch from which it cuts its oval case. It then mines the leaves. In late June to early August it aestivates, before feeding again and then constructing a final case by the following April. The ovum and case-bearing stage are described for the first time by Heckford & Beavan (2018). The final instar larva is shown mining the leaf.
