Uherkovich Ákos- Nógrádi Sára: 1992: Some data to the Trichoptera fauna of Drava River, Hungary Néhány adat a Dráva magyarországi szakaszának trichoptera faunájához
276 UHERKOVICH ÁKOS-NÓGRÁDI SÁRA typephaeopaHag. occurs mostly along large rivers (Danube, Dráva, Fekete-Körös, Rába, Marcal), but it was captured along small streamlets (Iharos and Szemenyecsörnye in County Somogy, South Hungary) or in the Balaton Lake, too (Fig. 4). It is relatively frequent and widely distributed in Szigetköz, NW Hungary, in the branch of Danube. This water, MosoniDuna is relatively unpolluted and flows very slowly. Several specimens were captured at a point of Balaton on the westerns shore of Tihany Penninsula, too. Cyrnus trimaculatus Curt, lives predominantly in small and quick-running streamlets, on the western part of Hungary, in Bakony Mountains and at several sites of the Northern Mountains. Its occurrence in Dráva River is far from other Hungarian localities, this is the only one South Transdanubian locality (Fig. 5). The distribution of Ithytrichia lamellaris Eaton - similarly to other hydroptilids - has only been known for a short time. It is a rare species in general, more Botosaneanu, L, Malicky, H, 1978.

It prefers clean, quickrunning waters (Fig. 6). Ceraclea annulicornis Steph. belongs to the sensitive species, too. Generally it is not common, its number of individuals is low. From all Hungarian localities 1-8 specimens are known, at Szentborbas 141 males and 49 females, altogether 190 adults were captured, thus this biotop seems to be optimum of this species (Fig. 7).
