Acer pseudoplatanus, Denmark, September 4 © Simon Haarder

cocoon

prepupa, dissected out of the cocoon

mine

A large, upper-surface (often nearly full depth) blotch, without a hint of a preceding corridor, beginning in the tip of a leaf segment. Frass in loose grains. The larva makes a discoidal cocoon within the mine; the cocoon is not cut loose, but drops with the leaf to the ground. Like in all Heterarthrus species the larva has thoracic feet that are reduced to triangular stumps.
