As early as 1980 David B. Weissman began publishing the results of his field and laboratory studies of the Gryllus of the United States and Canada (Weissman et al. 1980). By 2003, David Gray had started his cooperation with Weissman by providing genetic analysis of the living Gryllus made available by Weissman's studies (e.g., Weissman, Walker, and Gray 2009). Weissman and Gray's manuscript regarding the Gryllus of US and Canada was published in Zootaxa on 5 December 2019. [The manuscript will soon be made available.]
