Recorded only once for the Belgian fauna: Beez (NA), before 1906, when a caterpillar was found in the stem of Senecio vernalis. Hitherto probably extinct in our country.
Native
Wingspan about 16 mm.
In springtime the larvae spin the central shoots together and feed on the root-stock which is excavated and were pupation takes place.
Larvae of the summer generation live on the flower-buds and pupate in the flower-shoot.
Two generations a year in May and July–September.
The larva feeds on different species of Senecio.
It occurs in sandy localities and forest edges.
