Stigmella minusculella mine

Pyrus communis, Luxemburg, Kautenbach

Stigmella embonella mines

Pyrus spinosa, Rhodes (Nepticula embonella); from Klimesch (1978b)

mine

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.
