Description of early stages following Klimesch (1978).

Egg. The egg is laid on either side of a leaf.

Larva. The larva is light yellow, with green gut and light brown head capsule. It feeds on Prunus dulcis (Mill.) D. A. Webb exclusively to present knowledge. The mine is a gallery, mostly starting at underside and often associated with a leaf vein. In the early mine, the black broken frass almost fills the gallery. Later, the short gallery is contorted with bulked frass, leaving narrow clear margins. The exit hole of the larva is on the underside. The cocoon is yellowish-white.
