Rare
Under 5% of wildlife watchers report an Elm Agromyzid Leafminer sighting in Toronto on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1544th most-seen of the 1689 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 an Elm Agromyzid Leafminer in Toronto on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Elm Agromyzid Leafminer 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 5 cities where we can rate Elm Agromyzid Leafminer sightings, Toronto ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Boston (United States, under 5%), Washington (United States, under 5%) and New York City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Elm Agromyzid Leafminer is recorded against all the insects logged in Toronto (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.
