Scientific Name: Cicindela patruela
Taxonomy Group: Arthropods
COSEWIC Range: Ontario, Quebec
COSEWIC Assessment Date and Status Change: November 2009
COSEWIC Status: Endangered
COSEWIC Status Criteria: B1ab(iii)+2ab(iii)
COSEWIC Reason for Designation: This showy metallic green beetle inhabits sandy, open forest habitat dominated by pine and/or oak trees. Found in northeastern and northcentral North America, it is globally imperiled reaching its northern limit in southern Ontario where it is currently found at only two localities. The species has disappeared from one well known historic site. Habitat loss resulting from natural succession and increased pedestrian traffic are significant threats.
COSEWIC History of Status Designation: Designated Endangered in November 2009.
SARA Status: Schedule 1, Endangered
Date of Listing (yyyy-mm-dd): 2012-06-20

Northern Barrens Tiger Beetle (previously known as Patterned Green Tiger Beetle) is a member of the family Carabidae, order Coleoptera. Three subspecies of Cicindela patruela have been described, of which only the nominate subspecies patruela is found in Canada. This subspecies is recognized by its dull metallic green colour with a complete white middle band on the wing covers. It is 12–14.5 mm long. (Updated 2017/05/30)
Distribution and Population
The historic range of Northern Barrens Tiger Beetle includes Ontario, Quebec, and 24 states in the north–central and eastern US. Its occurrence is discontinuous and very local throughout its range. In Canada, it is historically known from three locations in Ontario and Quebec. It is believed extirpated at one of these sites, possibly extant at another and currently definitely known at only one. The only confirmed extant site in Canada is at Pinery Provincial Park. (Updated 2017/05/30)
Northern Barrens Tiger Beetle occurs along dry, sandy trails, little–used roads, and other small openings in oak–pine savannahs and mixed woods. Larvae use similar habitat, typically off to the side of paths in more consolidated soil and sparse ground cover of bracken fern, blueberries, grasses, mosses and lichens. Northern Barrens Tiger Beetle is often restricted to small areas within large patches of seemingly suitable habitat. (Updated 2017/05/30)
Northern Barrens Tiger Beetle has a 2–year life cycle. New adults typically emerge in early fall to feed, overwinter in burrows, and emerge the following spring to mate and lay eggs. Post–breeding adults may persist through most of the summer. Eggs hatch in early summer and each larva digs a burrow. Larvae become second or third instars by the autumn, overwinter underground, then continue through the second spring and summer as third instars before pupating in late summer. Adult Northern Barrens Tiger Beetle are active during warm, sunny weather, consuming a wide range of small invertebrates, particularly ants. Larvae are also predators, lying in ambush at the top of their burrows and grabbing passing prey. The adult beetles are preyed upon by robber flies and a variety of generalist predators.

Northern Barrens Tiger Beetle is at the northern limit of its range and has restricted habitat preferences. It is considered moderately to extremely threatened in its global range primarily due to habitat loss and degradation. In Canada, it is threatened by habitat degradation due to natural succession of savannah and woodland habitat to more shaded conditions, particularly as a consequence of lack of natural fire.

The Northern Barrens Tiger Beetle is protected under the federal Species at Risk Act (SARA). More information about SARA, including how it protects individual species, is available in the Species at Risk Act: A Guide.

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 Annual Reports
COSEWIC Annual Report - 2010 (2010-09-03)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”. During the past year, COSEWIC held two Wildlife Species Assessment Meetings and reviewed the status of 79 wildlife species (species, subspecies, populations). During the meeting of November 2009, COSEWIC assessed or reviewed the classification of the status of 28 wildlife species. COSEWIC assessed or reviewed the classification of an additional 51 wildlife species (species, subspecies and populations) during their April 2010 meeting. For species already found on Schedule 1 of SARA, the classification of 32 species was reviewed by COSEWIC and the status of the wildlife species was confirmed to be in the same category (extirpated - no longer found in the wild in Canada but occurring elsewhere, endangered, threatened or of special concern). The wildlife species assessment results for the 2009-2010 reporting period include the following: Extirpated: 6 Endangered: 39 Threatened: 16 Special Concern: 17 Data Deficient: 1 This report transmits to the Minister the status of 46 species newly classified as extirpated, endangered, threatened or of special concern, fulfilling COSEWIC’s obligations under SARA Section 24 and 25. A full detailed summary of the assessment for each species and the reason for the designation can be found in Appendix I of the attached report. Since its inception, COSEWIC has assessed 602 wildlife species in various risk categories, including 262 Endangered, 151 Threatened, 166 Special Concern and 23 Extirpated. In addition, 13 wildlife species have been assessed as Extinct. Also, to date, 46 wildlife species have been identified by COSEWIC as Data Deficient and 166 wildlife species were assessed as Not at Risk. This year has been a particularly productive year for COSEWIC’s Aboriginal Traditional Knowledge (ATK) Subcommittee. In April 2010 COSEWIC approved the Aboriginal Traditional Knowledge Process and Protocol Guidelines, providing clear and agreed principles for the gathering of Aboriginal Traditional Knowledge to carry out COSEWIC functions as required under Section 15(2) of SARA (See Appendix III of the attached report). We are grateful for the rich and enthusiastic contribution made by community elders and experts in helping the ATK Subcommittee prepare the ATK protocols.
