In 3 days ~20% in a week ~30%
Pachyta lamed is a bettle species of the Lepturinae subfamily in long-horned beetle family. This beetle is distributed in Austria, Belarus, Bulgaria, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Italy, Japan, Latvia, Lithuania, Moldova, Mongolia, Norway, Poland, Romania, Russia, Slovakia, Slovenia, Sweden, Switzerland, Ukraine, and in United States, and Canada. Adult beetle feeds on Norway spruce.
The larvae reside within the roots or stumps of dead or decaying coniferous trees, particularly spruce (Picea spp.) and fir (Abies spp.). During the larval stage, which can span many years, the beetles dig into the wood and feed on the decomposing tissues. Wikipedia →

With luck
About 10% of wildlife watchers report a Pachyta lamed sighting in Yellowstone National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 91st most-seen of the 160 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Pachyta lamed in Yellowstone National Park on a given day, against under 5% in October to June, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Pachyta lamed sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Pachyta lamed sightings, Yellowstone National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Jasper National Park (Canada, about 10%) and Banff National Park (Canada, about 10%).
Same family: Cerambycidae
The closest relatives of the Pachyta lamed that you can see in Yellowstone National Park (family Cerambycidae, Longhorn Beetles) are White-Spotted Sawyer (about 20%), Yellow Velvet Beetle (about 10%) and Hairy Pine Borer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pachyta lamed is recorded against all the insects logged in Yellowstone National Park (10 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.
