A common species throughout Belgium, but sometimes confused with the mines of Stigmella centifoliella.
Native
The mine is a long, and gradually widening gallery. The initial gallery is completely filled with frass. Later on the frass pattern can change abruptly from a thick central line into coiled frass, allways leaving clear margins.

It makes a red to red brown cocoon.
It pupates in the cocoon, generally spun on the surface of a leaf or a leaf-stalk.
The adults fly in two generations a year during May and August.
The larva makes a leafmine on Rosa and sometimes also on Sanguisorba.
