Scaphoideus titanus
In 3 days ~20% in a week ~30%
Scaphoideus titanus, the American grapevine leafhopper, is an insect of the leafhopper family (Cicadellidae) which feeds on various plants of the family Vitaceae. Native to North America, it was accidentally introduced to Europe where it has become a pest by acting as a vector of the grapevine phytoplasma disease flavescence dorée. Mating requires species-specific vibrational patterns that males emit to the females, which are susceptible to reproductive interference, including vibrational mating disruption caused by humans for pest control purposes. Nymphs do not engage in vibrational communication. Wikipedia →

With luck
About 10% of wildlife watchers report an American Grapevine Leafhopper sighting in Kyiv on a given day, based on 31 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.
August
In that month about 20% of wildlife watchers report an American Grapevine Leafhopper in Kyiv on a given day, against under 5% in September to June, the lowest months.
Only Kyiv, in our data
Kyiv is the only city on Wallace's Line with enough records to rate American Grapevine Leafhopper sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the American Grapevine Leafhopper is recorded against all the insects logged in Kyiv (31 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.
