Recent Status: A reasonably common species in Britain possibly under-recorded in Suffolk owing to identification constraints.
Life Style: A single brooded species flying during June and July and coming to light. The larvae feed on the seeds of Juncus species preferring J. acutiflorus and J. articulatus. They hibernate fully fed in the larval case where they pupate in the year following oviposition.
Identification: A small stripy species that can be identified by genitalia dissection. The larvae feed inside a seed until the third instar when they construct a silken case within a seed pod which is excised and remains around the case to be moved between seeds for feeding. More Info
