Rare
Under 5% of wildlife watchers report a Rose Sawfly sighting in Chicago on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 751st 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 Rose Sawfly in Chicago on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Rose Sawfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
20th of 20
Of the 20 cities where we can rate Rose Sawfly sightings, Chicago ranks 20th at under 5%. The best odds are in Tehran (Iran, about 20%), Barcelona (Spain, about 10%) and Valencia (Spain, about 10%).
Same order: Hymenoptera
The closest relatives of the Rose Sawfly that you can see in Chicago (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Common Eastern Bumble Bee (about 30%), Brown-Belted Bumble Bee (about 20%) and Two-Spotted Bumble Bee (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rose Sawfly is recorded against all the insects logged in Chicago (8 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.
