In 3 days ~10% in a week ~30%
Exocentrus lusitanus is a species of longhorn beetles of the subfamily Lamiinae. It was described by Carl Linnaeus in his 1767 12th edition of Systema Naturae. It is known from Europe and western Russia. The beetles inhabit broadleaf trees, particularly lime trees and sometimes hazels. The larvae feed on dead tree material under bark and in branches and twigs. They measure 3.5–6 millimetres (0.14–0.24 in) in length as adults, and can live for approximately two years. Wikipedia →

Rare
Under 5% of wildlife watchers report an Exocentrus lusitanus sighting in Vienna on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 373rd most-seen of the 1406 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.
June to August
In those months about 10% of wildlife watchers report an Exocentrus lusitanus in Vienna on a given day, against under 5% in September to May, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Yes
Of the 2 cities where we can rate Exocentrus lusitanus sightings, Vienna has the highest daily chance: under 5%. Next come Kyiv (Ukraine, under 5%).
GBIF citizen-science records
It is estimated from how often the Exocentrus lusitanus is recorded against all the insects logged in Vienna (70 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.
