Morley’s Final Catalogue: Discovered by the Bishop, who gave me a series, in numbers among Schoenus-rushes at Redgrave in 1932-4 (Waller).
Recent Status: Rare in Suffolk.
Life Style: A single or possibly double brooded species that can be found from June to September. The larvae feed on the seeds of Schoenus nigricans and Juncus bufonius. They pupate in a loose web in the seed head of the foodplant. They pass the winter as a pupa.
Identification: This species is exceedingly similar to the very common G. simpliciella. The only clear difference is that it has the hindwing dorsal cilia white basally. The forewing markings of both species vary and may be reduced but the costal strigulae are less evenly spaced in G. schoenicolella. A genitalia dissection may assist the determination of the species but this too is not easy. More Info The only sure way of recording the species is by rearing through larvae.
