Bionomics
At first, the caterpillar is living in a seed till it is about 1 mm. Then it makes a silken case upon which frass and plant rests and other things are constructed. Finally, the caterpillar disconnects itself from the seed and goes eating other seeds. Fully developed cases are greyish and 7–8 mm long. The caterpillars overwinter in the case.
Flight periods
The adults fly from the end June till the end of September.
