With luck
About 10% of wildlife watchers report a Two-Lined Hooktip sighting in Great Bear Rainforest on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 83rd most-seen of the 235 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Two-Lined Hooktip in Great Bear Rainforest on a given day, against under 5% in July to May, 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 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Two-Lined Hooktip sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Two-Lined Hooktip sightings, Great Bear Rainforest has the highest daily chance: about 10%. Next come Acadia National Park (United States, about 10%).
Same family: Drepanidae
The closest relatives of the Two-Lined Hooktip that you can see in Great Bear Rainforest (family Drepanidae, Hooktip and False Owlet Moths) are Lettered Habrosyne Moth (about 10%) and Tufted Thyatirine Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Two-Lined Hooktip is recorded against all the insects logged in Great Bear Rainforest (27 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.
