Upis ceramboides
In 3 days ~10% in a week ~20%
Upis ceramboides is a species of beetle, one of many wood-living insects that benefit from forest fires. It often occurs in quantities below the bark on the fire-damaged birches, but can sometimes be seen on other deciduous trees such as willow and aspen. The larvae thrive in the inner bark which is rich in mycelia, and in the sapwood. They develop into pupae during the summer months under the bark, and they develop over two or three years. The following spring they reproduce themselves.
It has over the years have disappeared from southern Sweden and is now only locally in the Norrland coast (Västerbotten and Norrbotten) as well as Canada and Alaska. The reason for the species' decline is probably the lack of fire-damaged forests and birch, and the modern forestry practices. Upis ceramboides is considered "vulnerable" in terms of species survival. In Vindeln municipality it is called köksskörven, because it occurs indoors when burning firewood in winter.
The species' survival at temperatures well below freezing are attributed to the xylomannan non-protein antifreeze molecule (polysaccharide and a fatty acid) as well as the sugar-alcohol, threitol. Other notable freeze-tolerant animals include the fly Polypedilum vanderplanki and the beetle Cucujus clavipes puniceus. Wikipedia →

Rare
Under 5% of wildlife watchers report a Roughened Darkling Beetle sighting in Edmonton on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 230th most-seen of the 390 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.
June
In that month about 10% of wildlife watchers report a Roughened Darkling Beetle in Edmonton on a given day, against under 5% in July to May, the lowest months. That is one of Edmonton's wettest months, with about 85 mm of rain against 20 mm in February.
Yes
Of the 2 cities where we can rate Roughened Darkling Beetle sightings, Edmonton has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Roughened Darkling Beetle is recorded against all the insects logged in Edmonton (9 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.
