A very rare and declining species in the southern part of Belgium, not seen for a while.
Native
Wingspan c. 19–30 mm. The antennae of the male is more tapered than the blunt-ended antennae of Adscita statices.
The larva begins by making a tiny full depth corridor. When the larva becomes bigger it starts living free. A number of times it makes a transverse slit in the lower epidermis, then it eats away the leaf tissue, penetrating into the mine with the frontal part of its . This is resulting in a number of fleck mines, without frass, with the opening in the form of a large, lateral slit. The larva mines till just before the pupation, that takes place externally.
The moths are active during the day.
The adults fly mainly during June.
The polyphagous larva feeds on different species of Centaurea and on Cirsium.
It inhabits calcareous soils and grasslands.
