Specimens in nature




In Belgium larvae are mainly found in stems of Artemisia vulgaris and Humulus lupulus. Copious amounts of frass are ejected. Infected stems of Artemisia vulgaris often break off just above the larval feeding place. The larva hibernates in the stem. Pupation takes place in a cocoon in the larval gallery. The pupa does not protrude the exit hole before emerging.

Flight periods

The adults fly from the end of May till the end of September. Most abundant in the second half of June and the beginning of July. They are active at night and come to light.
