With luck
About 10% of wildlife watchers report a California Bordered Plant Bug sighting in Yosemite National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 148th most-seen of the 227 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–April, June and September
In those months about 10% of wildlife watchers report a California Bordered Plant Bug in Yosemite National Park on a given day, against under 5% in May, July–August and October–February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most California Bordered Plant Bug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate California Bordered Plant Bug sightings, Yosemite National Park ranks 4th at about 10%. The best odds are in Joshua Tree National Park (United States, about 20%), Channel Islands National Park (United States, about 20%) and Sequoia and Kings Canyon National Parks (United States, about 10%).

GBIF citizen-science records
It is estimated from how often the California Bordered Plant Bug is recorded against all the insects logged in Yosemite National Park (9 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.
