摘要: This is the 22nd consecutive annual report on interesting irnds and provincial records of Mac-rolepidoptera in Sweden. Due to the limited number of new provincial records and an increasing demand for information on Lepidoptera for faunal conservation purposes, this list also gives a brief summary of the present status for some of the endangered lepidopteran species in Sweden. There is still a most unfortunate lack of information about many of these species. Hopefully, this material will be accumulated by lepidopterologists before these spe-cies have become extinct in Sweden. Presently, the Swedish Threatened Species Unit is compiling current knowledge on red listed species and therefore, there is an increasing need to obtain all available data. After a disobliging spring and early summer, extreme summer warmth arrived at the end of June and remained for more than a month, resulting in the hottest Julyinthesouthemhalf of Swedensince 19l0. However, thenumbersof individualsof most Macrolepidoptera species were distinctly lower than average, presumably due to the cool summer and extremely cold autumn 1993. The most striking find this season was the noctuid moth Xestia atrata, which is new not only to Sweden but also to Europe. This species is previously known from Canada, Alaska and eastem Siberia. Among other interesting records from the Swedish fauna were Acerbia alpina which for the first time was found in numbers, Callimorpha dominula which appears to be colonizing new sites in southemmost Sweden and Xestia borealis which were found on a new, somewhat more southerly habitat. From the end of July until almost the …
