Calathus opaculus LeConte, 1854

It is worth drawing attention to the records of this species published by Apigian & Wheelwright (2000) from Kent Island, New Brunswick since this species was not included in Goulet & Bousquet's (2004) compendium of New Brunswick carabid fauna. Apigian and Wheelwright found C. opaculus to be one of the two most abundant species on the island. Found in meadows, old fields, pastures, vacant lots, cultivated fields, lawns, hedges, sand hills, orchards, forest edges, and open forests on open or shaded dry, sandy soil ( Larochelle & Larivière 2003).
