Rare
Under 5% of wildlife watchers report a Rivulet Nocloa sighting in Joshua Tree National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 147th most-seen of the 190 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.
March and April
In those months about 10% of wildlife watchers report a Rivulet Nocloa in Joshua Tree National Park on a given day, against under 5% in May to February, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Rivulet Nocloa sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Joshua Tree National Park, in our data
Joshua Tree National Park is the only park on Wallace's Line with enough records to rate Rivulet Nocloa sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Rivulet Nocloa that you can see in Joshua Tree National Park (family Noctuidae, Cutworm Moths and Allies) are Ridings' Forester (about 10%), Arizona Bird-Dropping Moth (about 10%) and Red-Lined Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rivulet Nocloa is recorded against all the insects logged in Joshua Tree National Park (8 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.
