A rather rare species in Belgium.
Native
Wingspan: 11–15 mm.
The forewings are metal-golden with sometimes a little purplish shine. Near the apex a little bit darker.
The antennae are prominently thickened from the base till 1/5 or even 1/3.
The eggs are deposited on a flower of the host plant.
At first, the larva feeds from the green seeds. The larvae are full-fed in September. Cases from mid-August.
Pupation in the following spring, still in the case, in the seedhead or on the ground.
The adults are day-active, mainly before noon. They come infrequently to light.
They are on the wing from June till the beginning of August.
Trifolium pratense is the most common foodplant.
