Stigmella floslactella occurs in Ireland where it is known to feed on various hornbeam and hazel species, including Corylus advenella. It is considered to be an uncommon visitor to Belgium and the Netherlands, where it feed on Carpinus betulus and Corylus avellana. Ecology

The larvae feed on Carpinus betulus, Corylus avellana, Corylus maxima and Ostrya carpinifolia. They mine the leaves of their host plant. The mine consists of a slender, gradually widening corridor. The last section is considerably wider than the larva. The trajectory of the mine is not angular and is independent of the leaf venation. Pupation takes place outside of the mine. References
