The European hornet (Vespa crabro) is the largest eusocial wasp native to Europe. It is also the only true hornet (genus Vespa) found in North America, having been introduced to the United States and Canada from Europe as early as 1840. Vespines, such as V. crabro, are known for making intricate paper-like nests out of surrounding plant materials and other fibers. Unlike most other vespines, reproductive suppression involves worker policing instead of queen pheromone control, as was previously thought.
This species stings in response to being stepped on or grabbed, but generally avoids conflict. It is also defensive of its nest and can be aggressive around food sources. Care should be taken when they are found in these circumstances, as they may sting without warning. European hornets are largely carnivorous and hunt large insects such as beetles, wasps, large moths, dragonflies, and mantises. They also feed on fallen fruit and other sources of sugary food. Mutual predation between medium-sized hornets and the Asilidae (robber flies) is often reported.
The European hornet is a true hornet (genus Vespa), a group characterized by eusocial species. The genus is in the subfamily... Wikipedia →

Possible
About 20% of wildlife watchers report a European Hornet sighting in Kharkiv on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 24th most-seen of the 289 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July and August
In those months about 40% of wildlife watchers report a European Hornet in Kharkiv on a given day, against under 5% in May and November–March, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most European Hornet sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 53 cities where we can rate European Hornet sightings, Kharkiv ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Turin (Italy, about 20%).
GBIF citizen-science records
It is estimated from how often the European Hornet is recorded against all the insects logged in Kharkiv (33 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.
