A fairly common species in Belgium, with the bulk of observations in the northern part of the country.
The initial mine is a very thin corridor with a central reddish brown frass line. Later, it feeds externally and creates small fleck mines or windows, which is very obvious and typical for the species.

The young larva mines the leaf of Artemisia vulgaris.
The adults are active in late afternoon sunshine and later come occasionally to light.
The adults have been observed from late May till August.
