Confusion Species: Incurvaria masculella

ID pointers: Easily confused with I. masculella – The males of this species have simple antennae – An attractively marked little moth. The yellowish marking on the costa is closer to the wing tip. If present on masculella it is closer to the head than the opposing tornal spot.

Distribution: (Last record: 22/02/2025 at Longdendale, Wildboar Clough ) - Uncertain due to few records – One in 1971 then two in 2024 – likely to be found in localised colonies on the upland moors where there are Bilberry and Cloudberry growing.

Flight Period: June / July / - One generation in June – July

Mine Period: July / August / - The larvae feed on bilberry and cloudberry, and at first they mine the leaves creating a small blotch mine elongated to form a linear mine, then cut out a portable case and dropping to the ground. Here they feed on dead leaves.
