Leaf-mine:
Blotch mines reaching the edge of the leaf, initially pale green
turning brownish white, are caused by the larva feeding on the underside
of a leaf (UKMoths).
The case is illustrated in British
leafminers, UKMoths
and Nederlandse
bladmineerders.
Larva:
The larva starts feeding and case making in August, overwinters
half grown, recommences feeding in early March and is full-grown
in May (UKMoths).
The larva is illustrated in Nederlandse
bladmineerders.
Pupa:
Pupation from May to early June is in the case, usually attached
to a hard surface such as a rock or post (UKMoths).
