Morley’s Final Catalogue: A common kind on the same food-plant. Aldeburgh after 1890 (Ctw); Monks Soham garden, in June 1933, and Barnby Broad in August (Mly).
Recent Status: One of the more commonly recorded Elachista species in Suffolk.
Life Style: A single brooded species that comes to light and can be found from May to September. The larvae mine Dactylis glomerata and probably Carex species also. The larvae hibernate.
Identification: This is a larger dark winged species with creamy white markings. The frons is ochreous and the palps cream. There is a fascia at one third that is weak or interrupted centrally, there is a tornal and larger costal spot a little beyond. The costal spot often subtends a fine fascia that at first is angled towards the termen before turning in to meet the tornal spot. The markings of the female are bolder. The markings are variable however and if the head markings are not evident then genitalia dissection is necessary to support a record. More Info
