Morley’s Final Catalogue: By no means frequent with us, feeding on low plants. Observed before 1890 at only Lowestoft (Bd),' Beccles (Crf), and Tuddenham (Wrn). Gorleston in June 1933 (D).
Recent Status: A common species in Suffolk.
Life Style: A single brooded species flying from April to July. The larvae feed from spun leaves on a wide range of mainly herbaceous plants but occasionally on deciduous trees and shrubs. They pupate in a cocoon in the larval habitation.
Identification: A broad winged species that has a slightly deeper suffusion at the wing base and thorax, but lacks any discrete wing markings. A similar species Z. unitana lacks the suffusion and has paler or greyer wings. They can only be separated reliably by the structure of the male aedeagus. Z. unitana has not been recorded in Suffolk.
