If it would be
Phasia obesa in England, consider
Phasia aeneoventris in Quebec. They key out together in Sun and Marshall (2003) distinguished by distribution.
The revision depends on seeing sternite VII. For
aeneoventris: "Sternite VII (sheath) longer than sternite VI, tapered, pointed apically, not bent; apex straight; sternite VII with linear wrinkles ventrally. Ovipositor bent upward."

Sorry,
aeneoventris is the West Nearctic species that keys out with
obesa. In Quebec compare
Phasia robertsonii instead: "Sternite VII (sheath) longer than sternite VI, tapered, narrow apically, slightly bent, apex directed dorsally, sternite VII with linear wrinkles ventrally. Ovipositor bent upward."
