In 3 days ~10%
The Norfolk damselfly, Norfolk coenagrion or dark bluet (Coenagrion armatum) is a species of blue damselfly in the family Coenagrionidae, native to northern Eurasia from the Netherlands and Norway east to Kamchatka. This species acquired its common name from its discovery in 1903 and its presence in a very restricted area of the Norfolk Broads, England.
At first glance, this damselfly may resemble a blue-tailed damselfly or a red-eyed damselfly more than a typical Coenagrion species. Both sexes have a distinctive black abdomen with coloured segments at both the base and the tip. Males have very large appendages that distinguish them from similar species.
It breeds in ponds ditches and slow rivers with open helophyte vegetation (particularly in sparse Phragmites australis, Carex spp., and Equisetum fluviatile) and with oligotrophic water quality. It is abundant in northeastern Europe.
Its breeding biology is poorly known. The eggs are laid in the stems and leaves of aquatic plants. The larvae live among aquatic plants and probably emerge after one year. It was recorded in Britain from late May to late July. The current populations... Wikipedia →

Rare
Under 5% of wildlife watchers report a Norfolk Damselfly sighting in Moscow on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 992nd most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Norfolk Damselfly in Moscow on a given day, so our monthly data shows no clear season.
Only Moscow, in our data
Moscow is the only city on Wallace's Line with enough records to rate Norfolk Damselfly sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Coenagrion
The closest relatives of the Norfolk Damselfly that you can see in Moscow (genus Coenagrion, Northern Bluets) are Azure Damselfly (about 10%) and Variable Bluet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Norfolk Damselfly is recorded against all the insects logged in Moscow (29 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.
