Mottled Duskywing Great Lakes Plains population
Scientific Name: Erynnis martialis
Taxonomy Group: Arthropods
COSEWIC Range: Ontario, Quebec
COSEWIC Assessment Date and Status Change: November 2012
COSEWIC Status: Endangered
COSEWIC Status Criteria: B2ab(i,ii,iii,iv,v)
COSEWIC Reason for Designation: The population has disappeared from Quebec and now occupies a few, isolated locations in southern Ontario that continue to decline in number. Population numbers are also declining. The species is primarily threatened by habitat fragmentation, but also by habitat loss and degradation through, for example, development, natural succession, fire suppression, and extensive deer browsing.
COSEWIC History of Status Designation: Designated Endangered in November 2012.
SARA Status: No schedule, No Status

PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.

COSEWIC Status Reports
Mottled Duskywing (Erynnis martialis) is a butterfly in the skipper family (Hesperiidae). It is a medium-sized (wingspan 23-29 mm) dark grey skipper with a very mottled appearance and a characteristic purplish hue. Yellow-brown spots create the mottled hindwing pattern, which distinguishes the Mottled Duskywing from other duskywing butterflies.
Mottled Duskywing is taxonomically distinct with no known subspecies. It is also genetically distinct from its closest relatives. The Mottled Duskywing is a butterfly representative of some of the rarest ecosystems in Canada, such as oak woodlands, pine woodlands, tall grass prairies and alvars with dry or sandy soils and early successional habitat. The Mottled Duskywing is experiencing declines similar to other butterfly species that occupy similar habitats such as the Karner Blue, Frosted Elfin, and Eastern Persius Duskywing, all assessed as extirpated in Canada.
The population has disappeared from Quebec and now occupies a few, isolated locations in southern Ontario that continue to decline in number. Population numbers are also declining. The species is primarily threatened by habitat fragmentation, but also by habitat loss and degradation through, for example, development, natural succession, fire suppression, and extensive deer browsing.
COSEWIC Annual Reports
Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to “assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species”.
COSEWIC held two Wildlife Species Assessment Meetings in this reporting year (October, 2012 to September 2013) from November 25 to November 30, 2012 and from April 28 to May 3, 2013. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 73 wildlife species.
The wildlife species assessment results for the 2012-2013 reporting period include the following:
Special Concern: 19
Data Deficient: 4
Not at Risk: 1
Of the 73 wildlife species examined, COSEWIC reviewed the classification of 50 species that had been previously assessed. The review of classification for 26 of those species resulted in a confirmation of the same status as the previous assessment.
The Government of Canada is committed to preventing the disappearance of wildlife species at risk from our lands. As part of its strategy for realizing that commitment, on June 5, 2003, the Government of Canada proclaimed the Species at Risk Act (SARA). Attached to the Act is Schedule 1, the list of the species provided for under SARA, also called the List of Wildlife Species at Risk. Endangered or Threatened species on Schedule 1 benefit from the protection of prohibitions and recovery planning under SARA. Special Concern species benefit from its management planning. Schedule 1 has grown from the original 233 to 518 wildlife species at risk.

The status of wildlife species is assessed by an independent panel of expert Canadian scientists, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).
149 terrestrial species were assessed as at-risk by COSEWIC between 2009 and 2016 and are eligible for listing under the Species at Risk Act (SARA) to be considered by the Governor-in-Council (GIC) on the recommendation of the Minister of the Environment: 86 species would be new additions, 54 currently listed species would be reclassified and 9 species would be updated to reflect changes in their recognized designatable units. A three-year listing plan has been developed to address all 149 terrestrial species and listing decisions for most species are anticipated by the end of 2018.
Making amendments to Schedule 1 of SARA is a two-step process. The first step is for the GIC to propose an amendment through an order in council published in the Canada Gazette, Part I, for a 30-day public comment period. The second step is for the GIC to make a final decision on whether or not to make amendments to Schedule 1 of SARA, taking into consideration comments received during the 30-day public comment period. The amendments are made through an order in council published in the Canada Gazette, Part II. Both orders are accompanied by a Regulatory Impact Analysis Statement (RIAS) which presents the implications of listing the species or changing their status.
Publishing this plan on the Species at Risk Public Registry is intended to provide transparency about the Government of Canada’s plan to make listing decisions under the Species at Risk Act.
NOTE: The information presented below is intended to provide openness and transparency with respect to when terrestrial species might be considered for listing under Schedule 1 of the Species at Risk Act. It is intended to assist anyone who may wish to provide comments on such listing considerations. Given any number of factors can affect the timing of a listing decision; the Plan is subject to change. Accordingly, the Plan will be periodically updated.
