With luck
About 10% of wildlife watchers report a Rose Sawfly sighting in Detroit on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 156th most-seen of the 268 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June and August–September
In those months about 10% of wildlife watchers report a Rose Sawfly in Detroit on a given day, against under 5% in July and October–May, the lowest months.
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.
5th of 20
Of the 20 cities where we can rate Rose Sawfly sightings, Detroit ranks 5th at about 10%. 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 Detroit (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Common Eastern Bumble Bee (about 30%), Eastern Carpenter Bee (about 20%) and Brown-Belted 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 Detroit (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.
