Opilo mollis is a species of beetles in the subfamily Clerinae. The body is elongated body and measures 9-13 mm in length. It iscovered with light hair.The head is reddish-brow and coarsely punctured. The large compound eyes have lightly notched front edges, the long antennae have flattened basal segments and the maxillary palps have triangular terminal segments.
The pronotum is matte dark brown and has a longitundinal groove that fades toward the back. The punctures on the pronotum are coarse and dense. The elytra are dark chestnut usually with a pattern of three pairs of yellow spots located on the shoulders, middle, and tips of the elytra. The rows of punctures on the elytra aren’t particularly deep and reach about halfway along their length; further back, the punctures become irregular. The tips of the femora are brown as are the tibiae. The underside of the body is dark.
This beetle is a saproxylic species. Both the larvae and the adult insects are predators, specialized in hunting larvae and adult forms of xylophagous and cambium-feeding insects. Their prey includes larvae and pupae of click beetles, weevils, bark beetles, and longhorn beetles. The beetle larvae develop in the feeding sites of cambium- and wood-eating insects on various tree species.
This species has become almost cosmopolitan due to being transported with wood to different parts of the world. Wikipedia →

Rare
Under 5% of wildlife watchers report an Opilo mollis sighting in Vienna on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 955th most-seen of the 1406 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Opilo mollis in Vienna on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Opilo mollis sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 cities where we can rate Opilo mollis sightings, Vienna has the highest daily chance: under 5%. Next come London (United Kingdom, under 5%).
Same family: Cleridae
The closest relatives of the Opilo mollis that you can see in Vienna (family Cleridae, Checkered Beetles) are Bee-Eating Beetle (about 10%) and Clerus mutillarius (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Opilo mollis is recorded against all the insects logged in Vienna (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.
