With luck
About 10% of wildlife watchers report a Labrador Tea Leaf Miner sighting in Great Bear Rainforest on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 42nd most-seen of the 235 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Labrador Tea Leaf Miner in Great Bear Rainforest on a given day, against under 5% in May, July and October–February, the lowest months. That is one of Great Bear Rainforest's driest months, with about 150 mm of rain against 480 mm in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Labrador Tea Leaf Miner sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Great Bear Rainforest, in our data
Great Bear Rainforest is the only park on Wallace's Line with enough records to rate Labrador Tea Leaf Miner sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Gracillariidae

GBIF citizen-science records
It is estimated from how often the Labrador Tea Leaf Miner is recorded against all the insects logged in Great Bear Rainforest (30 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.
