Always mercury vapour bulbs with an output of 125 Watts were used in the first half of the nights (ÁBRAHÁM, UHERKOVICH 2000). During the active period of the caddisflies (from May until November) several adults of these insects were collected and preserved. Sometimes small portable light traps fitted with "blacklight tube" were also used by L. Ábrahám, of which caddisflies were also elaborated. The results of some daytime sweepings along the small brooks running at the northern foot of the mountains were unimportant. Notwithstanding, two species were collected by this way only. During these two years 50 species were pointed out on the basis of 3043 adults. Earlier - in the 70s - two other species (Hydropsyche ornatula McL. and Micropterna lateralis (Steph.)) were collected. The forests of the northern slope proved to be the most fruitful area from the point of view of caddisflies, under the Tenkes (409 m) and Csukma (348 m) summit, and in some cases many caddisflies swarmed along the slopes of Szársomlyó Hill. From time to time we visited the small brooks bordering the mountains at its northern foot, here further species were collected. These small water courses are polluted, thus there are only a few species living in them. The data of collecting sites are given in Table 1.
