Aphid Wasp - Female
Richmond Hill, York Region, Ontario, Canada

Size: ~ 6 mm
Another aphid hunter at my Sedum plants. A data point for Ontario; I hope I placed it correctly (I guess I'm reputable for always placing wasps incorrectly...)

Psenini?
Abdominal petiole looks too long for Pemphredon, but the truth is that it is very, very difficult to make a diagnosis from one image, even though this one is very good!

Thanks Eric
I really admire how you experts always go to great lengths to ID even the difficult wasps. Thank you for looking at my image.
I do have a second image which shows the petiole better (if that helps at all), but did not post it due to low quality. Let me know if there are any other specific characters that I should focus on, and I'll be happy to try and get some images for that. Thanks again!
