Thymelicus lineola, known in Europe as the Essex skipper and in North America as the European skipper, is a species of butterfly in the family Hesperiidae. With a wingspan of 2.5 to 2.9 cm (0.98 to 1.14 in), it is very similar in appearance to the small skipper, Thymelicus sylvestris. They can be told apart by the forward-facing flattish part of the antenna tip: in the Essex Skipper this face is black, whereas in the Small Skipper it is orange or brown. In males, there is a difference in the scent mark. In Essex Skipper this is a fine, straight, short dark line on the forewing, parallel to the wing edge; in the Small Skipper males, this line is bolder and bent. This butterfly occurs throughout much of the Palaearctic region. Its range is from southern Scandinavia through Europe to North Africa and east to Central Asia. It was only identified in the UK in 1889, and its range is expanding both in England and in northern Europe. In North America, this butterfly was accidentally introduced in 1910 via London, Ontario and has spread across southern Canada and into several northern US states. In many parts of the Northeastern United States it is the most abundant skipper. Wikipedia →

Rare
Under 5% of wildlife watchers report an Essex Skipper sighting in Kyiv on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 591st 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.
June and July
In those months about 10% of wildlife watchers report an Essex Skipper in Kyiv on a given day, against under 5% in August to May, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Essex Skipper 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 27
Of the 27 cities where we can rate Essex Skipper sightings, Kyiv ranks 22nd at under 5%. The best odds are in Helsinki (Finland, about 20%), Edmonton (Canada, about 10%) and Kharkiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Essex Skipper is recorded against all the insects logged in Kyiv (6 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.
