Rare
Under 5% of wildlife watchers report a Jewelweed Leaf-Miner Fly sighting in Shenandoah National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 571st most-seen of the 723 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.
June and August–September
In those months about 10% of wildlife watchers report a Jewelweed Leaf-Miner Fly in Shenandoah National Park on a given day, against under 5% in July and October–May, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Jewelweed Leaf-Miner Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 parks where we can rate Jewelweed Leaf-Miner Fly sightings, Shenandoah National Park ranks 2nd at under 5%. The best odds are in Great Smoky Mountains National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Jewelweed Leaf-Miner Fly is recorded against all the insects logged in Shenandoah National Park (7 verified sightings from 2019 to 2026), 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.
