Zeldzame libellen in Nederland in 1998, CWNO-mededeling 2

The submitted Dutch records of a selected number of rare dragonfly species are reviewed annually. Acceptability is judged independently by each of the committee members, based on the documentation available (e.g. descriptions, drawings and pictures). In this report the records of 1998 are presented. Of each accepted record the province, nearby city, date(s), number, sex and observers are given. In addition, not (yet) accepted records and records received without documentation are listed. Highlights of the odonatological year 1998 were undoubtedly the records of the first adult specimens of Gomphus flavipes since 1902. These records made clear that the larva found in 1996, which constituted the first record since 1902, was the forerunner of the return of this species in The Netherlands. Remarkable was the discovery of two populations of Somatochlora arctica on one single day bringing the known number of populations to three. In the dune-area a population of Leucorrhinia pectoralis was found after absence as breeding species for several decades. Also the first records ever for Sympecma fusca for the dune-area were made. In 1998 the third and fourth Dutch records of Anax parthenope were made. One of which constituted the highlight of the day for an excursion of 25 members of the Dutch Society for the Study of Dragonflies (NVL).
