Erasmoneura vulnerata is a species of leafhopper native to North America. The species was found to be in Europe in 2004 where it causes significant economic damage to grapevine yards. E. vulnerata is commonly found on wild and cultivated grapes from both continents. Its Latin name translates to "wounded Erasmoneura" from its original description.
Erasmoneura vulnerata was originally described by A. Fitch in 1851. Upon discovery, Fitch placed the species in the Erythroneura genus as "Erythroneura vulnerata". Over a century after original discovery, D. A. Young named Erasmoneura as a subgenus of Erythroneura. The species in question was then known as Erythroneura Erasmoneura vulnerata. It was not until 2006 that Erasmoneura was elevated to generic status, allowing the previously known Erythroneura vulnerata to be known as Erasmoneura vulnerata. Additionally, it was discovered that Erythroneura gradata was simply a seasonal color variation of E. vulnerata.
Adults have a body size of roughly 2.7-3.2mm long and their body has a yellow stripe that longitudinally divides it. A seasonal color dimorphism occurs, with the summer population possessing... Wikipedia →

Rare
Under 5% of wildlife watchers report a Wounded Leafhopper sighting in Montreal on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 694th most-seen of the 926 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Wounded Leafhopper in Montreal on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Wounded Leafhopper sightings, Montreal ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Wounded Leafhopper is recorded against all the insects logged in Montreal (8 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.
