Schmidt, Chris, 2005, 2004 moth survey for southwestern Yukon: Dept. of Environment: Whitehorse, Yukon, p. 15-15.
Summary
Introduction: ... As a directed effort to further document moths of limited geographic occurrence, an initial inventory of the southwestern Yukon was conducted in 2004. Survey efforts focused on habitats known to harbor species of limited occurrence, particularly sand dunes and low elevation grasslands / steppe. Alpine tundra was also surveyed, but to a lesser extent owing to the fact that many of the Beringian endemic species have a biennial life cycle and fly only in odd-numbered years (Lafontaine & Wood 1997). Although Yukon's boreal habitats are undoubtedly home to many species not yet documented from this territory, the boreal fauna is generally transcontinental in distribution, and survey work was not explicitly carried out to [...]

Introduction: ... As a directed effort to further document moths of limited geographic occurrence, an initial inventory of the southwestern Yukon was conducted in 2004. Survey efforts focused on habitats known to harbor species of limited occurrence, particularly sand dunes and low elevation grasslands / steppe. Alpine tundra was also surveyed, but to a lesser extent owing to the fact that many of the Beringian endemic species have a biennial life cycle and fly only in odd-numbered years (Lafontaine & Wood 1997). Although Yukon's boreal habitats are undoubtedly home to many species not yet documented from this territory, the boreal fauna is generally transcontinental in distribution, and survey work was not explicitly carried out to sample boreal habitats (although many of the species reported here for the first time from the Yukon are boreal species). One-hundred and twenty-two species were identified from the 2004 survey work, representing 13 families. Ten species are here considered to be of special interest, with a known distribution either entirely restricted to the Yukon, or having geographically disjunct populations in the Yukon. The only lepidoteran species currently thought to be restricted to sand dunes in the Yukon include several species of Gnorimoschema, found only in areas with active dunes. Twenty-seven species are reported for the first time from the Yukon. Owing to the lack of taxonomic information available for many of the lesser-known microlepidoptera, a number of species still await identification, and many of these species will also undoubtedly represent new records for the Yukon; only about 11% of the micro-moths expected to occur in the territory have been documented (Lafontaine & Wood 1997) (Author)
