With luck
About 10% of wildlife watchers report a Grappletail sighting in Redwood National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 101 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 and July
In those months about 20% of wildlife watchers report a Grappletail in Redwood National Park on a given day, against under 5% in August and October–May, the lowest months. Those are among Redwood National Park's driest months, with about 25 mm of rain a month against 360 mm in January.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Grappletail sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Redwood National Park, in our data
Redwood National Park is the only park on Wallace's Line with enough records to rate Grappletail sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Odonata
The closest relatives of the Grappletail that you can see in Redwood National Park (order Odonata, Dragonflies and Damselflies) are Pacific Forktail (about 10%), Common Green Darner (about 10%) and Cardinal Meadowhawk (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Grappletail is recorded against all the insects logged in Redwood 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.
