The caterpillar is dark yellow to light brown. The thoracic segments are usually broader than the abdominal ones. Its head capsule, first thoracic segment and last abdominal segment are blackish.

The mine consists of an opaque white gallery on the upperside of a leaflet, soon widening into a whitish blotch and most of the time occupying one half of the leaf. But in later stages it covers the whole leaflet and turns a little bit darker. Frass is ejected through a hole in the epidermis.
