This widespread Eurosiberian species is known as an autumnal, hyporhitral-potamal species in most of its range. Early spring imagoes were reported only from the Iberian Peninsula in Europe, the present data from February is the first non-autumnal report from the Balkans. The single male found above Bašibos shows no notable morphological difference from autumnal specimens previously collected in Macedonia.
