Smaragdina salicina is a species of short-horned leaf beetles belonging to the family Chrysomelidae, subfamily Cryptocephalinae. This leaf beetle lives in Europe, in the eastern Palearctic realm, and in the Near East. The adults are 4.5–6.5 millimetres (0.18–0.26 in) long. The colours of head and elytra of this beetle are dark blue, while pronotum is reddish and legs are yellowish.
They mainly feed on Salix and Crataegus species, but also on leaves of various other plants (Blackthorn Prunus spinosa, Trifolium species, etc.). At the time of egg-laying they wrap their eggs in an envelope of their own excrement and drop them on the ground from above, manoeuvring with their hind legs. Wikipedia →

Under 5% of wildlife watchers report a Smaragdina salicina sighting in Kyiv on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 527th 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 30%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Smaragdina salicina in Kyiv on a given day, against under 5% in June to March, the lowest months.

GBIF citizen-science records
It is estimated from how often the Smaragdina salicina is recorded against all the insects logged in Kyiv (9 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.
