Eumenes crucifera
In 3 days ~10% in a week ~20%
Eumenes crucifera, also known as the cross potter wasp, is a North American species of potter wasp found in Canada, the United States, and Mexico. E. crucifera has a "range of variation mainly in coloration". In part due to this phenotypic variation, there were previously four recognized subspecies, one of which (Eumenes flavitinctus) has been elevated to full species status, and three of which have been eliminated and upmerged back into E. crucifera as of 2018.

Rare
Under 5% of wildlife watchers report a Cross Potter Wasp sighting in Vancouver on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 374th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cross Potter Wasp in Vancouver on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Cross Potter Wasp is recorded against all the insects logged in Vancouver (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
