With luck
About 10% of wildlife watchers report a Pistachio-Grass Root Aphid sighting in Sierra Nevada National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 390th most-seen of the 479 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
September and November
In those months about 20% of wildlife watchers report a Pistachio-Grass Root Aphid in Sierra Nevada National Park on a given day, against under 5% in July–August, October and December–May, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Pistachio-Grass Root Aphid sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Sierra Nevada National Park, in our data
Sierra Nevada National Park is the only park on Wallace's Line with enough records to rate Pistachio-Grass Root Aphid sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Pistachio-Grass Root Aphid is recorded against all the insects logged in Sierra Nevada National Park (15 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.
