We observed Archilestes californicus McLachlan (California Spreadwing), a damselfly in the family Lestidae, for the first time in south coastal British Columbia. Other records of the species in the Pacific Northwest document a gradual northward range expansion over the last twenty years. In light of this history, Archilestes californicus is expected to spread more widely in southern British Columbia. https://doi.org/10.32942/X23M3W Entomology Archilestes Published: 2026-03-30 10:10 Last Updated: 2026-03-30 10:10 CC BY Attribution 4.0 International Data and Code Availability Statement: Open data/code are not available Language: English
