Plant Parasites of Europe

leafminers, galls and fungi

oviposition scar

In cases where the egg is deposited within the plant tissue, this is done either by means of an ovipositor, or by biting a hole in the leaf (mostly a thick vein). This causes a wound reaction of the plant, that may remain long after the mine has been vacated.

Fenusa dohrni: mines

Fenusa dohrni: mines, each one with an oviposition scar.

Orchestes fagi: oviposition scar

Orchestes fagi, a weevil. A female, that has no ovipositor, gnaws a hole in the underside of the midrib, and deposits an egg in the wound.
