It is the 434th most-seen of the 1111 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.

Among the best
Of the 4 cities where we can rate Dark-Horned Trembling Woodwasp sightings, Moscow ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, under 5%), Berlin (Germany, under 5%) and Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Dark-Horned Trembling Woodwasp is recorded against all the insects logged in Moscow (20 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.
