Coptodisca lucifluella

Coptodisca lucifluella (Clemens, 1860)

on Carya, Juglans, Pterocarya


Oviposition, by way of an ovipositor, at the underside of a leaf. From here a full depth blotch develops, ± 5 x 7 mm, with dispersed frass. Generally several mines, irregularly distributed, over the leaf. The full grown larva makes a case out of an oval excision at the edge of the mine; in this case it leaves the leaf to pupate elsewhere on the tree.

Carya cordiformis; Juglans regia; Pterocarya fraxinifolia.
