Carpinus betulus, Cadzand: aberrant mine

mine

Oviposition at the underside of the leaf, in a vein axil. Mine a slender, gradually widening corridor; the last section is clearly wider than the larva. In the first section the vaguely delimited frass line almost fills the corridor. Later the frass lies in irregular arcs and clouds, filling about one third of the width of the corridor. The trajectory of the mine is not angular, independent of the leaf venation. Pupation external, exit slit in the upper epidermis.

host plants

Betulaceae, oligophagous

Carpinus betulus; Corylus avellana, maxima.
