Rare
Under 5% of wildlife watchers report a Cloudy Masked Bee sighting in Sydney on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 279th most-seen of the 742 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 Cloudy Masked Bee in Sydney on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Cloudy Masked Bee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Cloudy Masked Bee sightings, Sydney has the highest daily chance: under 5%. Next come Brisbane (Australia, under 5%) and Melbourne (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Cloudy Masked Bee is recorded against all the insects logged in Sydney (25 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.
