The fauna of the trichoptera (insecta) of Beyler dam lake (Kastamonu-Devrekani)

In order to determine the taxonomic composition, biodiversity and abundance of the Trichoptera fauna of the Beyler dam lake, 5 stations determined and sampled between June-September of 2016 and 2017. In this study, 24 adults, 673 larvae and 11 pupae were collected. A total of 15 taxa, belonging to 9 genus of 5 families (Glossosomatidae, Psychomyiidae, Hydropsychidae, Limnephilidae, Leptoceridae) were identified. While the highest diversity and abundance of caddisflies were found at the 1st station, the lowest diversity and abundance were found at the 5th station. In addition, the abundance and diversity of Trichoptera taxa were determined to be highest in June and lowest in September. Agapetus nimbulus McLachlan, 1879 (Glossosomatidae) and Anabolia nervosa Curtis, 1834 (Limnephilidae) were new record for the Trichoptera fauna of Turkey. In addition to these, 5 caddisflies species are new record for Kastamonu Trichoptera fauna. As a result of this study, the number of Trichoptera taxa in Turkey reached to 484 and in Kastamonu reached 76.
