Previously known only from old records from 2 Belgian provinces (BR & LG). In 2009 rediscovered in LG where the species is known from a few places and nowadays (2020) rare is, but in some old abondoned zinc mines where zinc violet grows, the species is not uncommon.
At first the larva mines in a petiole of the foodplant and later on it lives between the roots. Pupation between debris on the ground.
The adults are active during the day, especially in the morning and afternoon and are attracked to yellow flowers, e.g. Taraxacum spp, Hieracium spp, Bellis perennis, and Lotus corniculatus.
One generation a year: from mid-April till mid-June.
