In 3 days ~10% in a week ~30%
Scrobipalpopsis tetradymiella is a moth in the family Gelechiidae. It was described by August Busck in 1903. It is found in North America, where it has been recorded from California, Arizona and Nevada. The wingspan is 15.5–20 mm. The forewings are whitish, evenly and thickly overlaid with gray and fuscous scales giving the species a pepper and salt appearance. Toward the apex, the veins are slightly indicated by nearly unsprinkled whitish thin lines, with their interspaces rather more overlaid with dark scales than the rest of the wing. The hindwings are nearly transparent, light gray with silvery reflections.
The larvae feed on Tetradymia canescens, feeding from within stem galls. Wikipedia →

Rare
Under 5% of wildlife watchers report a Scrobipalpopsis tetradymiella 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 164th 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.
August
In that month about 20% of wildlife watchers report a Scrobipalpopsis tetradymiella in Joshua Tree National Park on a given day, against under 5% in January–July and September–October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Scrobipalpopsis tetradymiella sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
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 Scrobipalpopsis tetradymiella sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Scrobipalpopsis tetradymiella that you can see in Joshua Tree National Park (order Lepidoptera, Butterflies and Moths) are White-Lined Sphinx (about 40%), Painted Lady (about 40%) and California Patch (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scrobipalpopsis tetradymiella 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.
