Finding the Moth
Larva: mines the stems and leaves with a preference for the lower leaves which it completely hollows out towards the tip. It will readily move from one leaf to another spinning a slight web as it progresses. Later it feeds within the flowers and seedheads.
Adult: has occasionally been found amongst the larval foodplants.
The small size and rather plain grey-brown forewings should help differentiate if from pale or worn specimens of the larger S. artemisiella.
Single brooded with few flight records, those being between mid-May and early June (latest on the 9th in The Burren).
