The green hairstreak (Callophrys rubi) is a small butterfly in the family Lycaenidae. The genus name Callophrys is a Greek word meaning "beautiful eyebrows", while the species Latin name rubi derives from Rubus (bramble), one of the host plants.
Callophrys rubi sibirica (Rühl, 1895) Tien-Shan, Altai, Siberia, Transbaikalia, Far East, Amur (Outer Manchuria), Ussuri and Sakhalin. Callophrys rubi has a wingspan reaching about 26–30 millimetres (1.0–1.2 in) in length. The oversides of the wings are a uniform dull brown, with two paler patches on the male's forewings made up of scent scales. The undersides are a bright green with a thin white line, often reduced to a faint row of dots or even missing altogether. The iridescent green colour of the undersides is a structural colour caused by diffraction and interference of light by microscopic repeating structures forming a diffraction grating in the wing scales.

Rare
Under 5% of wildlife watchers report a Green Hairstreak sighting in Kyiv on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 655th most-seen of the 753 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.
May
In that month about 10% of wildlife watchers report a Green Hairstreak in Kyiv on a given day, against under 5% in June to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Green Hairstreak sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 12
Of the 12 cities where we can rate Green Hairstreak sightings, Kyiv ranks 11th at under 5%. The best odds are in Helsinki (Finland, about 10%), Stockholm (Sweden, about 10%) and London (United Kingdom, about 10%).

GBIF citizen-science records
It is estimated from how often the Green Hairstreak is recorded against all the insects logged in Kyiv (5 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.
