Detailed view
     

Egg. The egg is laid on the underside of a leaf.

Larva. The larva mines the leaves of birch, i.e. Betula pubescens, Betula pendula and Betula nana (Johansson et al. 1990). Following Ellis (2018), the species is said to feed also on Betula humilis and Betula pubescens subsp. carpatica.

Mine. The mine is a long and slender gallery. In the first fourth of its length, it is filled with greenish brown frass, after an abrupt transition, the black frass line is centered in the gallery, leaving clear margins.

Diagnosis:

Externally, the species is very similar to the variable Stigmella confusella (Wood & Walsingham, 1894) and cannot be distinguished from it with certainty. In the -genitalia, the cornuti of the aedeagus are all of equal size in S. confusella, whereas in S. lapponica cornuti of two different sizes are recognizable. The mines of both species are similar too. In S. lapponica however, the first fourth of the mine is completely filled with greenish brown frass, whereas in S. confusella the frass line is black and delicate from the beginning on, leaving clear margins.
