Euura proxima is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae feed on the leaves of willows (Salix species), creating galls. It was described by Jean Guillaume Audinet-Serville in 1823. The species was placed in the genus Euura in 2014 and was previously known as Nematus proximus and Pontania proxima.
The larvae have a darkened head, typically seen as they increase in maturity. Once they emerge from the gall, they form a cocoon. This cocoon takes on soil particles and leafy matter, having a fibrous texture. Overall, it is described as being cylindrical in shape with a golden brown color, the thickness depending on the developmental stage of the specimen.
The body of adult E. proxima is mostly black with a brown hue, the legs being a lighter, reddish-brown tone. A distinctive feature of this species is its thread like antenna which have shorter antennomeres compared to other similar species. This species is a part of Hymenoptera, which can be identified through multiple facets. For example, Hymenoptera have four membranous wings, mandibulate mouthparts and a true ovipositor. Mandibulate mouthparts are identified by multiple... Wikipedia →

Rare
Under 5% of wildlife watchers report a Willow Redgall Sawfly sighting in Vienna on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1090th 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 20%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Willow Redgall Sawfly in Vienna on a given day, against under 5% in December to October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Willow Redgall Sawfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 18
Of the 18 cities where we can rate Willow Redgall Sawfly sightings, Vienna ranks 16th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Birmingham (United Kingdom, about 10%) and London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Willow Redgall Sawfly is recorded against all the insects logged in Vienna (7 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.
