very rare and local species in Belgium.
larva lives on Scutellaria
First mining, later in a loose spinning in a shoot or between two
leaves. It is not known how the winter is passed, but most probably in
the adult stage, because the usual food plant is often flooded during
winter and would not produce sufficient growth in early spring to
adults fly at least in two generations per year;
onwards from late May till July and again from August to early
September.They are active during the day flying over the food plant and
later come to light.
imago very similar to Prochoreutis myllerana, subtle differences can be looked up in
Diakonoff, Microlepidoptera Palaearctica, Vol. 7. Mines are similat to P. myllerana, but
the larvae are distinguishable.
