Bionomics
The larva feeds on the seeds and roots and hibernates full-fed in a cocoon between bark and pith in a last years dead stem of the food plant. The larva prepares an exit hole. The pupa protrudes the stem before emerging.
On warm sunny days the males flies in the afternoon around their food plants, while the females hides at the bases and later come to light.

The adults have usually been observed from end of May till late August in one generation.
