Kovács, L.: Data to the knowledge of Hungarian Macrolepidoptera VI. Data with respect to migrating and spreading species

The light trap at Kunfehértó captured the first dolabraria specimens in the sixth year of its operation, in 1967. The first exemplar was caught on 13 May, indubitably representing the first generation. As for a time no more appeared, it was regarded as an "Irrgast". In July, however, also the second generation appeared, represented by 7 specimens between 2—29 July. From then on, the fact of occupation could no more be doubted. In 1968, the first brood appeared already on 11 May, again a single representative. Thesecond brood was essentially weaker in this year, with merely 3 exemplars representing it between 28 June —11 July. In 1969, individual numbers have unexpectedly increased. The first brood flew between 6—25 May in this year, represented by 4 cf and 59- The second generation was on the wing between 6 July —14 August, represented by 22 cf and 4 Ç. In 1970, individual numbers increased still further: of the first brood 18 cf and 1 9 were captured between 26 April —18 May, of the second one 52 cf 6 9 between 12 July —41 August. The rocketing increase of dolabraria suggests that it found favourable conditions in its newly occupied locality. The starting point of the spreading of the dolabraria population, settled in the environs of Kunfehértó, cannot safely be established yet. The nearest known locali­ties, Hőgyész in the west and Tass in the north, are about at equal distances from Kunfehértó. Since, however, a dolabraria specimen was captured in 1967 also at Tolna by the light trap situated there since seven years, and another one in the next year, and as Tolna lies in about the midpoint of the distance between Hőgyész and Kunfehértó, it seems more probable, for the time being, that the immigration happened from the west. The examples discussed above prove convincingly that the data deriving from regularly conducted mass surveys, and collatable both territorially and temporally, have a fundamental importance in the study of problems connected with the move­ments of Lepidoptera. The limited scope at our disposal naturally precludes even an approximately full exposition of the possibilities at hand. And if the study of problems connected with the movements of Lepidoptera could be made in an international cooperation, regardless of state borders, the possibility of comparisons at a higher level could also be opened, with results of universal validity.
