The banded demoiselle (Calopteryx splendens) is a species of damselfly belonging to the family Calopterygidae. It is often found along slow-flowing streams and rivers. It is a Eurasian species occurring from the Atlantic coast eastwards to Lake Baikal and northwestern China.
This is a common species throughout much of its range. This is a large damselfly with a total length of up to 48 millimetres (1.9 in) and a hindwing length of up to 36 millimetres (1.4 in). Male and female are variable in color and pattern. The male has translucent wings which each have a broad, dark iridescent blue-black spot (or band) across the outer part. On immature individuals the spot is dark brown. The body can be a metallic blue or bluish green or a combination of both colours, depending on the time of year and location.
The dark wing patch of the male starts at the nodus (the slight dip midway down the upper edge of the wing) but can reach up to the wing-tip in southern races. In the very similar beautiful demoiselle (Calopteryx virgo), the dark patch starts before the nodus.
The female has translucent, pale green iridescent wings with a white patch near the tip (a pseudopterostigma)... Wikipedia →

With luck
About 10% of wildlife watchers report a Banded Demoiselle sighting in Kyiv on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 277th most-seen of the 753 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Banded Demoiselle in Kyiv on a given day, against under 5% in September to April, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Banded Demoiselle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
22nd of 31
Of the 31 cities where we can rate Banded Demoiselle sightings, Kyiv ranks 22nd at about 10%. The best odds are in Turin (Italy, about 30%), Leeds (United Kingdom, about 20%) and Brussels (Belgium, about 20%).
Same order: Odonata
The closest relatives of the Banded Demoiselle that you can see in Kyiv (order Odonata, Dragonflies and Damselflies) are Black-Tailed Skimmer (about 20%), Blue-Tailed Damselfly (about 20%) and Ruddy Darter (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Banded Demoiselle is recorded against all the insects logged in Kyiv (17 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.
