Caterpillar
Pale yellowish green; head capsule pale brown; prothoracic plate very pale brown.
Cocoon/pupa
Pupa yellowish brown laying in a tough, white sliken cocoon, head upwards.
Bionomics
The larva makes a gallery of up to 25 cm in the pitch of the stem, preferably in larger, thicker stems. On the outside there is no indication of their presence. When cutting an infected stem open in the lower half, one can notice the gallery that had been cut across. The gallery and frass are even more visible when splitting the stem in 2.
Before pupation the larva makes an exit hole leaving a thin piece of round or oval brown bark. The pupa does not protrude the exit hole before emergence.
The species hibernates in the adult stage.
Flight periods
One generation a year: from late August, and after hibernation untill April.
Habitat
Dry situations, waste ground where a lot of the foodplant is growing. According to literature It avoids stands of the foodplant in damp areas, but in Belgium larvae were found at river banks and in wet forests.
