Coptotriche angusticollella

The adults are a fairly uniform bronzy brown, or golden brown and have a wingspan of about 9 mm.  The larvae, like other Coptotriche species, produce a pale, papery blotch mine on the upperside of the leaves of various rose species. The mine often contorts the leaf causing it to fold upwards and may conceal the mine.
