This secretion later forms the oblong-oval crusty ootheca with an average size of 1.03 to 1.32 mm in length.

Even after the hatching and formation of the leaf mine, this process and the ootheca outer wall are intact.

[2][4] The first instar hatched out of the egg mines and starts to feed and move through the mesophyll tissues.

The larval head is chitinous brown and body translucent-greenish, where the alimentary canal is visible in dark green after feeding mesophyll tissues.

[2][6][7] It has observed that Braconid wasps parasitize mature instars and ants attack pupa.
