Museum specimens
Specimens in nature
Caterpillar
Yellowish or greenish; head capsule, first thoracical segment and last abdominal segment blackish.
Mine
A white, elongated blotch mine, continuously enlarged. The inside of the mine is lined with spinning, causing the mine to contract slightly. Frass is ejected through a small whole at the underside of a leaf. The mine of this species could be confused with that of the very rare Coptotriche heinemanni, also occurring on Rubus, but the mine of that species if yellowish-brown.

Cocoon/pupa
No cocoon is formed.
Bionomics
The eggs are oviposited on the upperside of a leaf.
The species hibernates in the larval stage, inside the mine, without making a cocoon, and still feeding during winter whenever the temperature is not too low. Pupation in early spring.

The adults fly in two generations a year: May–June and August.
