Waters, 1929583 / 37.070

Morley’s Final Catalogue: Not listed.

Recent Status: Few records in Suffolk.

Life Style: A single brooded species flying during June, July and August. The larvae feed on the seeds of Juncus 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. More Info
The larvae initially feed inside a seed before constructing a silken case inside one. As they grow the case enlarges, is trivalved and splits the original seed which remains as parts attached to the anterior part of the case. The oral opening is set at 15 to 20 degrees to the long axis. More Info

Determination by Genitalia Examination (gen. det.) Required

Case: A good quality photo or specimen of the case and plant/pabulum is required.
