Egg
at the underside of the leaf. The mine is a not very strongly contorted
corridor, also not limited to a small portion of the leaf, and usually
not forming a secondary blotch. Frass black. The frass line is very
narrow, especially in the first section of the mine. In the second
part the line may be broader, with the frass dispersed or indistinctly
coiled, but always the width of the frass remains less than a third
of the width of the corridor (Bladmineerders van Europa). |
