Természettudományok - Nógrádi U., Sára–Uherkovich, Ákos: The Trichoptera fauna of the Zselic Downs, Hungary

TRICHOPTERA FAUNA OF THE ZSELIC 17 Fig. 2. Collecting sites of Zselic on UTM grid map of Hungary. 2. ábra. A zselici gyűjtőhelyek Magyarország UTM rendszerű hálótérképén. of 59 species. This was one of the richest trap materials for caddisflies in Hungary. Several rare species were captured here, e. g. Limnephilus elegáns Curt., Lasiocephala basalis Kol., Phacopteryx brevipennis Curt, and Hydroptila forcipata Eaton. The two operators, Mrs. Margit Juhász and Mrs. Erzsébet Vajda handled the trap excellently. In the year of 1987 a new trap has been set up in Santos village, on the bank of Surján Stream (Fig. 3). While the previous two traps killed the insect material by chloroform, here it was substituted by ethylenglycole. Although in this liquid the Lepidoptera material suffers heavy damage, the caddisflies are preserved in excellent condition. The trap was in action periodically (May 18-30, June 14-29, July 27-August 5, August 14-31, September 18-28, October 18-28). During these six periods 1411 specimens of 43 species were captured. Because of the light polluted water no rarities were collected. The operators were Mr. Mihály Szentgyörgyi and Mr. Gyula Póczik. At Almamellék-Sasrét a light trap of the Forestry Research Institute was set up years ago to indicate forestry pests. The leader of the trap network, Miss Katalin Leskó has handed over the caddisfly material of the years 1985 and 1986. The material was rather unvaried since 94.19 per cent of it was Ecnomus tenellus Ramb. 1875 specimens of 28 species were captured. Two remakable species are Hydroptila dampfiUlmer and Orthotrichia tragetti Ulmer. At Bőszénfa-Ropolypuszta and Pale lepidopterological light traps functioned years ago. The Trichoptera material was picked out partly and elaborated by Dr. Sándor Újhelyi and the authors. The bulk of these data has been published (Nógrádi et al. 1985). During our night collections mercury vapour bulbs (125 or 250 Watts) were used with a sheet of 7 sq. m. The lamp was fed by a portable Honda generator (E300, EX500). Larger materials were collected by this way at three fish ponds (Csertő, Patosfa and Somogyapáti) and along the Almás Stream at Szulimán and Bükkösd Stream at Szentlőrinc (see Table 1 and Fig. 1). Altogether 16 841 Trichoptera were collected at 37 sites which represent 83 species. List of the material In this section all the species collected in the Zselic Downs are enumerated, with references to literature or locality, date and number of specimens. A short characterization is given at each species. Since the bulk of material was collected by the authors and the light traps, the collector's name is not given. Other collectors are (Á) = Levente Ábrahám, (F) = Sándor Farkas, (U, M) = Ákos Uherkovich and Hans Malicky. The brackets show that a dead specimen was collected (e. g. from spider's web). In case a species was collected five or more times in the same locality within a year, the first and the last date are given with the collective number of specimens. Hyphenated dates may mean that the material was captured during this period (e. g. we got the total material from 1 till 16 July). The system and nomenclature of Botosäneanu and Malicky (1978) is followed.
