With luck
About 10% of wildlife watchers report an Exotic Streaktail sighting in Channel Islands National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 102nd most-seen of the 131 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.
April, June and August
In those months about 10% of wildlife watchers report an Exotic Streaktail in Channel Islands National Park on a given day, against under 5% in May, July and September–March, the lowest months. Those are among Channel Islands National Park's driest months, with almost no rain against 60 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Exotic Streaktail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Channel Islands National Park, in our data
Channel Islands National Park is the only park on Wallace's Line with enough records to rate Exotic Streaktail sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Exotic Streaktail is recorded against all the insects logged in Channel Islands National Park (6 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.
