Scientific research for the conservation of the species
The purpose of this study is to determine the distribution, abundance, and habitat associations of the Dusky Dune Moth. Non lethal nighttime light trapping will be undertaken at locations where the species has been observed and on suitable habitat not previously surveyed. This information is necessary to aid in the recovery of the species, including identification of critical habitat. One to four traps, depending upon the size of the sand dunes, will be operated from dusk until dawn for one to three nights. Traps will be checked each morning shortly after dawn. After identification, target and non-target moths will be released in nearby shaded dense vegetation cover. A voucher specimen may be collected from each site. An attempt will be made to identify the host plant species. A clipping of the potential host plant species may be collected for positive identification. There is a small possibility of incidental capture of the diurnal Gold Edged Gem and nocturnal White Flower Moth due to similar habitat preferences. This is an amendment to the permit to add two new locations in Saskatchewan and a new assistant.

Location of Activity (province, territory or ocean):
Because the moths are nocturnal light trapping is the only feasible method to undertake surveys. Moths will be caught in live traps. The traps will be lined with paper egg cartons to provide hiding places. The traps will be set at dusk and checked each morning. Moths will be released in adjacent shrub or grass cover to provide hiding places. If moths are successfully captured in the light trap on the first night then the traps will not be deployed a second night, thus reducing the risk of negatively impacting the local population. Only one voucher specimen will be taken from each site. Worn, and hence older, individuals will be collected preferentially over fresher-looking individuals, and males will be collected preferentially over females. To minimize habitat disturbance, habitat will be approached on foot. Plant clipping will occur only in the circumstance where the plant species cannot be identified in the field. The potential for capture of the Gold Edged Gem and White Flower Moth is deemed limited due to the former’s diurnal habit and the latter’s geographic separation.
