Anchomenus dorsalis
In 3 days ~10% in a week ~20%
Anchomenus dorsalis is a species of ground beetle in the subfamily Platyninae. It is found in Europe, North Africa, West and Central Asia. This beetle is bright green-blue and red-brown in color. The adults are 5.6–7.7 mm long, with females larger than males.
This beetle forms aggregations of several individuals, often with beetles of the genus Brachinus. When disturbed it releases a volatile that contains undecane. Its coloration may be aposematic mimicry of the similarly colored Brachinus beetles it lives with, which emit a much more powerful antipredator volatile mix. Wikipedia →

Rare
Under 5% of wildlife watchers report an Anchomenus dorsalis sighting in Moscow on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 286th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Anchomenus dorsalis in Moscow on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Anchomenus dorsalis sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
4th of 6
Of the 6 cities where we can rate Anchomenus dorsalis sightings, Moscow ranks 4th at under 5%. The best odds are in Bucharest (Romania, about 10%), Vienna (Austria, under 5%) and Nizhny Novgorod (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Anchomenus dorsalis is recorded against all the insects logged in Moscow (37 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.
