This species is rather widely distributed in western North America from Mexico to British Columbia, with most of the records from California, United States (Whitfield and Oltra-Moscardo 2004, Whitfield 1985). It is only know in Canada from one female specimen (British Columbia, specimen deposited in the CNC), by far the northernmost record, and representing less than 5% of the global range of the species. It has been reared from two species of Bucculatrix (Lepidoptera: Bucculatrigidae) feeding on plants of Artemisia spp., Baccharis pilularis, and Iva axillaris (information summarized in Yu et al. 2012).

Assessment using the prioritization criteria developed by COSEWIC. Existing global conservation status: None (species is not listed on Natureserve nor has it been assigned a Canadian national conservation status rank). Canadian population size and trends: No information on population size is available. Threats: Residential and commercial development – high (the single area where the species occur in Canada is populated); Agriculture and aquaculture – unknown; Human intrusions and disturbance – medium; Natural system modifications – high (alteration of the area would likely extirpate the species from Canada); Invasive and other problematic species and genes – unknown but likely low, unless another wasp species parasitizing the same host would be introduced (and then competing for the same host, an scenario not likely to occur); Climate change and severe weather – unknown but likely low (climate change increasing the temperatures would not affect much the presence of this species in Canada, because it is already distributed in warmer areas). Small extent of occurrence or area of occupancy: Recorded from one locality in Canada. Limiting biological factors: Probably none.
