Members of Psilopa are typically found in saline, alkaline, or mineral-enriched wetland including salt marshes, mineral springs, and evaporative pond margins. The specific microhabitat preferences of P. obscuripes have not been independently documented.
Distribution
Described from North American material; precise type locality and contemporary range boundaries remain insufficiently documented. GBIF records suggest scattered North American occurrences, though verification of identifications is needed.
