Plant Parasites of Europe

leafminers, galls and fungi

Caryocolum marmorea

Caryocolum marmorea (Haworth, 1828)

beautiful groundling


In Cerastium the young larva makes an irregular, semitransparent, upper-surface corridor, running usually from the leaf tip to the base along the midrib or the leaf margin. The oldest part of the mine is filled with greenish brown frass. From the leaf the larva bores itself into the stem. It is not known whether the larva behaves similarly in Silene. The older larva feeds on the leaves from a silken tube or between spun leaves.
