Genitalia
Bionomics
The eggs are laid on the flowers of the food plant. The young caterpillar initially lives inside a seed of the host plant and, later on, uses an empty seed to move around and feed on the inside of other seeds.
So, this species is a seed-feeder. The caterpillar leaves its feeding place before wintertime and moves down to hibernate, mostly in leaf litter. There, it pupates in springtime.
Flight periods
The moths fly from late May till the end of July, exceptionally till late August.
