Taxonomic Note

The authorship of this has been cited differently in various sources. GBIF lists it as Agonum collare (Say, 1830) with accepted status, while Catalogue of Life lists Agonum collare (Letzner, 1851) as an ambiguous synonym. This discrepancy reflects historical complications in ground beetle and .

Data Deficiency

Available sources provide minimal -specific information for A. collare. Most knowledge about this species is inferred from -level characteristics of Agonum, which contains over 100 species globally. Detailed ecological studies and modern taxonomic revisions are lacking.
