Specimens in nature



The mine is characterised by a narrow gallery, containing linear black frass and later leading to a small clear blotch. Subsequently the larva frequently changes its mine, and sometimes also its leaf, making a series of irregular clear blotches from which all frass is ejected. On the underside of the leaf, the larva also constructs an open network of silken threads which provide a platform from which the larva can eat and rest.
