Rare
Under 5% of wildlife watchers report a Chaparral Shieldback 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 159th 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.
June and July
In those months about 10% of wildlife watchers report a Chaparral Shieldback in Yosemite National Park on a given day, against under 5% in August to May, the lowest months. Those are among Yosemite National Park's driest months, with about 25 mm of rain a month against 220 mm in January.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Chaparral Shieldback sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
2nd of 2
Of the 2 parks where we can rate Chaparral Shieldback sightings, Yosemite National Park ranks 2nd at under 5%. The best odds are in Sequoia and Kings Canyon National Parks (United States, about 10%).
Same family: Tettigoniidae
The closest relatives of the Chaparral Shieldback that you can see in Yosemite National Park (family Tettigoniidae, Katydids) are Mormon Cricket (about 10%) and Alpine Shieldback (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chaparral Shieldback 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.
