(Haworth, 1828)290 / 15.012

Morley’s Final Catalogue: Not listed.

Recent Status: A locally common species.

Life Style: A double brooded species that hibernates. It can be found throughout the year. The larvae feed on Acer species, primarily Acer campestre. They pupate under a membrane on the underside of a leaf.

Identification: Caloptilia species stand erect on their front legs at rest. C. semifascia is a very variably marked species. The forewings and front leg femur and tibia are a general brown colour speckled, spotted and shaded darker. The colour may vary from ochreous cream to dark brown and tinged, orange, red or purple. A common form has a white oblique mark on the costa at one third that bends to go parallel to the costa. The wing is invariably darker in advance of this mark.. Another form has a sharply defined yellow costal blotch in the place of and beyond the white mark. The blotch is square topped distinguishing it from species that have more triangular blotches. The species includes the form hauderi previously with species status.
The larvae mine the underside of the leaf from where the ovum was laid to a small blotch mine. They then roll the leaf from the tip sealing the ends by turning the leaf side lobes or on A. pseudoplatanus form a neat cone. More Info

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