Rare
Under 5% of wildlife watchers report a Witchhazel Leafminer sighting in Boston on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 297th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August and September
In those months about 10% of wildlife watchers report a Witchhazel Leafminer in Boston on a given day, against under 5% in October to July, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Witchhazel Leafminer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Witchhazel Leafminer sightings, Boston has the highest daily chance: under 5%. Next come Washington (United States, under 5%) and New York City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Witchhazel Leafminer is recorded against all the insects logged in Boston (45 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.
