Rare
Under 5% of wildlife watchers report a Red Megacerus sighting in Chicago on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 637th most-seen of the 978 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 Red Megacerus in Chicago on a given day, so our monthly data shows no clear season.
Among the best
Of the 5 cities where we can rate Red Megacerus sightings, Chicago ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Detroit (United States, under 5%), Washington (United States, under 5%) and Montreal (Canada, under 5%).
Same family: Chrysomelidae
The closest relatives of the Red Megacerus that you can see in Chicago (family Chrysomelidae, Leaf Beetles) are Spotted Cucumber Beetle (about 10%), Swamp Milkweed Leaf Beetle (about 10%) and Dogbane Leaf Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red Megacerus is recorded against all the insects logged in Chicago (10 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.
