Distributional notes. This fly is uncommon in the southern Interior valleys of British Columbia from the Princeton and Ashcroft areas east through the Okanagan to the Columbia Valley at Robson; it is recorded in the far north at Atlin. Based on records in adjacent jurisdictions, the species is likely widespread over much of the province’s Interior. There are two occurrences in the south-central Yukon (LaForce and Ethel lakes); almost certainly the species ranges throughout the southern Yukon and probably across much of boreal Canada.
