Rare
Under 5% of wildlife watchers report a Common Marauder sighting in Chicago on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 884th most-seen of the 978 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Common Marauder in Chicago on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Common Marauder sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Common Marauder sightings, Chicago ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Marauder is recorded against all the insects logged in Chicago (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.
