(Haworth, 1828)290 / 15.012
Norfolk status

Now thought to be bivoltine in some counties including Norfolk with two distinct forms for each brood.
The Summer brood showing a triangular costal blotch while the Autumn (hibernating) second brood shows a distinctive angled light streak starting at the leading edge of the forewing.

Leaf-mine: June-July
gallery leading to a squarish blotch, later forming up to 3 leaf tubes/cones.

On Sycamore, the feeding signs can also be confused with those of C. rufipennella and will need rearing to confirm.

Scattered VC27 records. First confirmed VC28 record in 2013 when cones were collected on Silver Maple at Lynford Arboretum and bred through. This is thought to be a new foodplant record for this species. (I. Barton, K. Rosewarne)

[MBGBI Vol2 p268]

Please note:

The rare C. hemidactylella can only be separated as mines from C. semifascia by rearing through.

Morphology and DNA barcodes show that Calybites hauderi does not occur in the British Isles, but are the first brood of bivoltine Caloptilia semifascia. (Langmaid et al. 2011. Nota Lepidopterologica 33, 191-197).

Mine: Moth needs to be reared and, in some cases, possibly dissected.

Recorded in 43 (58%) of 74 10k Squares.
First Recorded in 1874.
Last Recorded in 2021.
