This xerothermic species is very rare and local in Belgium, recently (2012) discovered again after an absence of more than 150 years.
Native
The species hibernates in the egg stage.
The first instars mine in the leaves of the host plant, where they cause a large blotch. Later instars construct a tube from leaves which they spin together.
The adults come to light.
One generation a year: from late May till August.
Oligochagous on Campanulaceae, like: Campanula persicifolia, C. rotundifolia.
It has also been observed once on Scabiosa columbaria.
