Lepidoptera were collected, primarily via UV light trap, for three seasons in the boreal mixedwood forest near Lac La Biche, Alberta. A total of 11 111 specimens were collected, representing 41 families and 438 species. A species list with flight times is presented. The total Lepidoptera community was estimated to be 546 ±23.34 species. Abundance and species richness peaked in late July. Thirty-five species constitute new records for Alberta, while one species, Acanthopteroctetes bimaculata, is a new record for Canada, and the first record of the family Acanthopteroctetidae in Canada. Key Words: Moths, butterflies, Lepidoptera, Lac La Biche, Alberta, flight times, Acanthopteroctetes bimaculata, new to Canada.

to 5 October in 1994, and 28 May to 28 August in 1995. Traps were hung at approximately 1.6 m from the ground, and activated from dusk until dawn. These samples were augmented by periodic hand collecting at portable UV lights, and a small amount of net col- lecting of day-flying species. Specimens were identi- fied using a wide array of taxonomic publications, and by comparing to specimens in the Canadian Forest Service’s Northern Forestry Centre Research Collec- tion (NFRC) in Edmonton, Alberta, and the Canadian National Collection (CNC) in Ottawa, Ontario. Vouch- er specimens have been deposited at the NFRC and CNC. To obtain an estimate of the total size of the Lepi- doptera community in the study area, a Chao-1 estimate of diversity (Chao and Lee 1992) was calculated as described by Colwell and Coddington (1994).

Results A total of 11 111 specimens were collected, repre- senting 41 families and 438 species (Table 1). A list of all species collected appears in Table 2. Some species, particularly micro-moths, are identified here merely as morphospecies, reflecting the lack of knowledge of the group, and the difficulty in making species identi- fications. Examples of some of the micro- species collected appear in Figure 2; some of the macro-moths are illustrated in Figures 3 and 4. The Chao-1 calcula- tion estimated the total size of the Lepidoptera com- munity in the study area to be 546 ± 23.34. The 1994 data is examined in detail here, since it FIGURE 1.

In 1994, both abundance (Figure 5) and species richness (Figure 6) peaked dramatically in late July. A major flush of occurred in late July, with the highest species richness occurring older than the planned stand rotation age (60-70 years) throughout July and into early August.
