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 →

GBIF citizen-science records
It is estimated from how often the Wood Leopard Moth is recorded against all the insects logged in Porto (23 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.
