Tachyerges salicis: larvae in the mine

the mine contained several larvae

Tachyerges salicis: oviposition scar??

no oviposition scars could be found on the lateral veins; the interpretation of this scar is unclear

Tachyerges salicis

pupation in cocoons in the mine; the material has been bred, the identification was confirmed by Marc Delbol


Oviposition in the underside of a lateral vein. From here develops a large, full depth transparent light brown blotch that expands irrespective of the leaf venation. Mine mostly in the distal half of the leaf, may eventually occupy half of its surface. The mine often tears in, and the leaf tip is disfigured. The larva eventually pupates in a globular cocoon within the mine (Scherf, 1964a).
