Arctopsyche ladogensis Kolenati 1859 .

There is a distinct light stripe along the frontal and coronal sutures of the head continuing mesally on the thoracic nota ( Fig. 2A ). The gular sclerite (ventral apotome) tapers towards the posterior end ( Fig. 2C ). The larvae are retreat-makers and do not construct cases. This species sporadically occurred in assemblages of Trichoptera on water moss but was abundant in samples of shining pondweed Potamogeton lucens L. collected at sampling site 2/1.
