Morley’s Final Catalogue: Local in salt-marshes, on Juncus compressus. Taken on rushes in salterns at Aldeburgh on 22 June 1904 only (Morley).
Recent Status: One of a number of salt-marsh Coleophora species. Status is uncertain owing to identification constraints. Juncus gerardii and J. compressus are easily confused so the Morley record being on salt-marsh is probably correct.
Life Style: A single brooded species that can be found in June and July. The larvae feed on seeds of Juncus gerardii.
Identification: A greyish ochre species with a pale costa to two thirds. They can be reliably identified by genitalia dissection. More Info The larvae initially feed by boring into J. gerardii seeds and then create a case from one of them in which they pupate. More Info
Determination by Genitalia Examination (gen. det.) Required
Case: A good quality photo or specimen of the case and plant/pabulum is required.
