Rare
Under 5% of wildlife watchers report a Widow Yellowjacket sighting in Baltimore on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 620th most-seen of the 705 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 Widow Yellowjacket in Baltimore on a given day, so our monthly data shows no clear season.

Across all the parks we cover, that three-hour window holds the most Widow Yellowjacket sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Widow Yellowjacket is recorded against all the insects logged in Baltimore (5 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.
