Leaf-mine:
The larva feeds on rose, building successively larger portable cases
from cut-out leaf fragments; September 3mm, October to April 6mm.
In mid-April the third and final, 6 or 7 mm, case is formed. At
first it is spatulate with a bivalved anal opening and serrate dorsal
keel formed from a leaf margin. During May, the case is expanded
dorsally, becoming cylindrical with a trivalved anal opening. The
expansion may conceal the dorsal serration (UKMoths).
The leaf damage and case are also illustrated in British
leafminers.
