Abstract


Jentzsch, M., Glinka, T., Link, J., Lehmann, B.: Use of a car-net in the Ziegelroda forestry - results and comments on the method (Arachnida: Araneae, Pseudoscorpiones; Insecta: Ephemeroptera, Odonata, Hemiptera, Coleoptera, Hymenoptera, Lepidoptera, Mecoptera, Diptera). - Hercynia N.F. 50 (2017): 31 – 93.

In the late summer of 2012 and in the early summer of 2013 the invertebrate fauna of the Ziegelrodaer Forst in the south of Saxony-Anhalt was collected by car-net. The recording of data took place three times daily on eleven days and on six different tracks especially in forest- and partially in open grassland-habitats. A total of more than 198 samples were collected. The intention was to make a contribution towards testing the car-net concerning its ability to catch invertebrates. Approximately 65.5% of more than 200.000 captured specimens belong to the order of Diptera, followed by the order of Coleoptera with a percentage of about 17.6%, whereas the third highest amount of about 11.6% was determined by the order of hymenoptera. The fourth and fifth places are taken by the order of Hemiptera at a percentage of round about 1.6% and the class of Arachnida with approximately 0.5%. The share of the remaining groups of species is around 0.6%. Altogether 2.5% of the collected material was classified as undeterminable.

Additional to a huge amount of species included in the Red List of endangered animals of Germany and of Saxony-Anhalt, a total of six new records could be registered for Germany and another 18 records for Saxony-Anhalt. Four species were rediscovered in Saxony-Anhalt. Some species of different taxa are still undescribed and thus new to science. The evaluation of the collected sample material has shown that the car-net method is a valuable addition to common collection methods, it provides large amounts of individuals and species and promises the greatest success in capturing beetles and flies.

Key words: Car net, arthropods, invertebrates, method, red list, Auchenorrhyncha, Coleoptera, Diptera, Heteroptera, Hymenoptera, Saxony-Anhalt.
