A rather common species in Belgium, especially in the northern part.
Native
From autumn till spring the larva lives in a male catkin, causing it to deform somewhat. Later the larva moves to a developing bud. They pupate in a cocoon on the ground.
The adults come to light.
The adults fly in two generations a year from April till early October. The first generation is the most numerous with a peak in May.
It inhabits gardens, parks, woodland, heatland and downland.
