Staudinger, 1859552 / 37.077

Morley’s Final Catalogue: Not listed.

Recent Status: This species has been recorded at two locations in Suffolk.

Life Style: A double brooded species that flies by night and comes to light. It can be found during May, June, July and August. The larvae feed on the seeds of Juncus bufonius. They use a seed eaten capsule for a case and attach to the end of another seed to feed. They hibernate and continue feeding in spring before pupation. Some may hibernate fully grown.

Identification: This is a small species with greyish buff forewings and pale stripes often obscure. They can be identified by genitalia dissection. More Info
The larvae that use the seed capsule as a case can be identified from making a hole in the end of a seed on the plant rather than the side. This separates them from other Juncus seed feeding species. More Info

Determination by Genitalia Examination (gen. det.) Required

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