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 →

Rare
Under 5% of wildlife watchers report a Red Flat Bark Beetle sighting in Vancouver on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 192nd most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Red Flat Bark Beetle in Vancouver on a given day, against under 5% in June to April, the lowest months. That is one of Vancouver's driest months, with about 60 mm of rain against 210 mm in November.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Red Flat Bark Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 10 cities where we can rate Red Flat Bark Beetle sightings, Vancouver ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Minneapolis [Saint Paul] (United States, under 5%) and Edmonton (Canada, under 5%).
Same order: Coleoptera
The closest relatives of the Red Flat Bark Beetle that you can see in Vancouver (order Coleoptera, Beetles) are Asian Lady Beetle (about 30%), Seven-Spotted Lady Beetle (about 10%) and Twenty-Spotted Lady Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red Flat Bark Beetle is recorded against all the insects logged in Vancouver (27 verified sightings), 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.
