Természettudományok - Uherkovich, Ákos–Nógrádi, U. Sára: Trichoptera fauna of a typical cultivated region of the Carpathian Basin by light trap examination

TRICHOPTERA OF A CULTIVATED REGION 29 XP cu Fig. 2. Location of Kocsola in the grid map of Hungary (BS85). 2. ábra. Kocsola elhelyezkedése Magyarország hálótérképén (BS85). Discussion The first data from Kocsola were published by Nógrádi et al. (1985). The number of species per year is relative moderate, the summarized number of species within seven years is pretty high. But the composition of species is unvaried excepting of some more interesting species. 5 of total 47 species can be more noteworthy as it follow. Brachycentrus subnubilus Curt, became a rarity in the past decades supposing the more polluted waters. Only one or two specimens were collected in every site (five sites in South and West Transdanubia: Kocsola, Kisdobsza, Kaposfő, Szentlőrinc, Bozsok). Grammotaulius nitidus Müll, is much rarer in South Transdanubia than in the other parts of Hungary. Till recent days it has been known only from Pécs (old data from Fauna Regni Hungáriáé, Mocsäty 1900) and from Tolna (Nógrádi et al. 1985). Phacopteryx brevipennis Curt. Data about the first Hungarian male were published by Nógrádi (1984) from Szőce. Later we and our light traps captured this species at Kőszeg, in the Kőszeg Mountains, Kisdobsza, Darány, Lipótfa and Nagybajom. In the latter site it is pretty frequent. Stenophylax meridiorientalis Mai. is a recently described species (Malicky 1980) which occurs on the southern half of Transdanubia. The northernmost point of ist occurrence is the Bakony Mountains. In the PilisDunazug Mountains (Nógrádi et al. 1989) and in the Northern Mountains (Nógrádi-Uherkovich 1988) Stenophylax vibex Curt, lives. It is very likely that the specimens (two males) captured at Kocsola is immigrated from the Mecsek Mountains. Several limnephilid caddisflies swarm far and wide after their hatching out to have a summer diapause. The distribution and frequency of Colpotaulius (Limnephilus) incisus Curt, has changed in the past years considerably. This species was a relatively rare one before 1985. It hardly had literature data and specimens of collections. During 1982-1984 we collected only very few specimens, also. In 1985 twenty-two, in 1986 fiftyFig. 3.
