Rare
Under 5% of wildlife watchers report a Spotted Pine Sawyer sighting in Yosemite National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 174th 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 August–September
In those months about 10% of wildlife watchers report a Spotted Pine Sawyer in Yosemite National Park on a given day, against under 5% in July and October–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 noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Spotted Pine Sawyer sightings with a recorded time, and about 8 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 Spotted Pine Sawyer sightings, Yosemite National Park ranks 4th at under 5%. The best odds are in Grand Canyon National Park (United States, about 10%), Rocky Mountain National Park (United States, about 10%) and Jasper National Park (Canada, about 10%).
Same genus: Monochamus
The closest relatives of the Spotted Pine Sawyer that you can see in Yosemite National Park (genus Monochamus, Sawyer Beetles) are White-Spotted Sawyer (about 10%) and Monochamus obtusus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spotted Pine Sawyer is recorded against all the insects logged in Yosemite National Park (6 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.
