Zeuzera pyrina, the leopard moth or wood leopard moth, is a moth of the family Cossidae. It is considered a pest by fruit growers, as the larvae feed on branches of many kinds of fruit trees. Olive trees in particular are very susceptible and can be killed by the larvae burrowing within them.
This species can be found primarily in Europe (excluding Ireland) but also in northern Africa (Algeria, Egypt, Libya, Morocco) and Asia (Taiwan, India, Iran, Iraq, Israel, Japan, Korea, Lebanon, Sri Lanka, Syria, Turkey). It was introduced into the northeastern United States prior to 1879 and has a range including Maine, Pennsylvania, Tennessee and Texas.
These moths are associated with woodland, gardens and orchards. Zeuzera pyrina has a wingspan of 35–60 millimetres (1.4–2.4 in). They are a highly distinctive species. The length of the abdomen of the female is about 45–50 millimetres (1.8–2.0 in). The... Wikipedia →

With luck
About 10% of wildlife watchers report a Wood Leopard Moth sighting in Vienna on a given day, based on 88 verified sightings from GBIF citizen-science data. It is the 190th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Wood Leopard Moth in Vienna on a given day, against under 5% in September to April, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Wood Leopard Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 28 cities where we can rate Wood Leopard Moth sightings, Vienna ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Bucharest (Romania, about 10%) and Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Wood Leopard Moth is recorded against all the insects logged in Vienna (88 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.
