Crematogaster pilosa

Crematogaster pilosa is truly a habitat specialist. In Ozarks of Missouri, it is rarely found anywhere other than in the vegetationally unique, spring fed, wet meadows. And yet, they occur in and are often abundant in nearly every one of these widely distributed, but sporadic habitat remnants [J. Trager, October 2016]

Identification
A member of the Crematogaster scutellaris group.

Distribution based on Regional Taxon Lists
Nearctic Region: United States.
