Cucujus clavipes is known as the flat bark beetle. It is found throughout North America. These are generally found near tree line under bark of dead poplar and ash trees. C. clavipes are described as phloem-feeding and often predators of other small insects, such as wood-boring beetles, and mites. These are usually seen during spring-summer seasons. Having a cold habitat, these beetles must go through several physiological mechanisms to survive; they are recognised for their ability to change their overwintering mechanisms.
C. clavipes can be found in North America [1] over a broad latitudinal range from North Carolina (latitude ~35°N) to the Brooks Range in Alaska (latitude, ~67°30 N) and has also been reported in Alberta [2] and in Ontario, Canada. C. clavipes has two subspecies, C. clavipes clavipes, which resides in the Eastern portion of the North America and C. clavipes puniceus in the West. These are poikilothermic organisms.
The beetles are between 10 and 14 mm in length,. Their body tends to be strongly dorsoventrally flattened and their sides parallel. Their abdomen has 5 visible ventral segments. These have strongly forked median... Wikipedia →

With luck
About 10% of wildlife watchers report a Red Flat Bark Beetle sighting in Sequoia and Kings Canyon National Parks on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 60th most-seen of the 161 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April

GBIF citizen-science records
It is estimated from how often the Red Flat Bark Beetle is recorded against all the insects logged in Sequoia and Kings Canyon National Parks (11 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.
