 Before 1995, "P. fuscatus" was the only species of "Polistes" in Michigan.In the spring of 1995, one single founder colony of "P. dominula" was discovered nesting in the "Polistes" nestbox at the Oakland University Preserve in Rochester, Michigan.In 2002, about one-third of the "P. dominula" colonies at the preserve were removed because of the concern about losing the resident population of "P. fuscatus".
